-
- * src/src_sinc.c
- Fix a read beyond end of coefficent array problem uncovered by gcc-4.8's
- -fsanitize=address feature and reported by Cristian RodrÃguez.

-Install Instructions for libsamplerate
-======================================
-
-The following instructions explain how to install libsamplerate under
-Linux and other Unix like systems including Mac OSX. (For windows,
-see http://www.mega-nerd.com/SRC/win32.html).
-
-Preliminaries
--------------
-1) Included with libsamplerate is a command line program named
- sndfile-resample which uses libnsdile:
-
- http://www.mega-nerd.com/libsndfile/
-
- for file I/O. If you want to use sndfile-resample you need to
- ensure that libsndfile is correctly installed first. If it is, the
- command "pkg-config --cflags --libs sndfile" should print out
- something like this:
-
- -lsndfile
-
- If pkg-config doesn't exist you will need need to install it. If
- pkg-config cannot find libsndfile you may need install it. If you
- install from from a Linux distribution package, make sure you also
- install the libsndfile-devel package which contains the header files.
-
- If libsndfile is installed, you may need to set the PKG_CONFIG_PATH
- environment variable. If libsndfile is installed in /usr/local/lib,
- you will need to set PKG_CONFIG_PATH using:
-
- export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
-
- Pkg-config should now work. If it doesn't you need to fix it if you
- want to use sndfile-resample.
-
-2) The included tests suite for libsamplerate needs libfftw3 which is
- available here:
-
- http://www.fftw.org/
-
- If FFTW3 is not available, libsamplerate should still compile and
- install without problems but the test suite will not be as
- comprehensive as it normally is.
-
-Building
---------
-Building and verifying libsamplerate is a four or five step process.
-
-1) The first step is to run configure
-
- ./configure
-
- which should print out something like the following:
-
- checking build system type...
- ...
- ...
- -=-=-=-=-=-=-=-=-= Configuration Complete =-=-=-=-=-=-=-=-=-=-
-
- Configuration summary :
-
- Version : ..................... X.Y.Z
- Enable debugging : ............ no
-
- Tools :
-
- Compiler is GCC : ............. yes
- GCC major version : ........... 3
-
- Extra tools required for testing and examples :
-
- Use FFTW : .................... yes
- Have libsndfile : ............. yes
-
- Installation directories :
-
- Library directory : ........... /usr/local/lib
- Program directory : ........... /usr/local/bin
- Pkgconfig directory : ......... /usr/local/lib/pkgconfig
-
- Compiling some other packages against libsamplerate may require
- the addition of "/usr/local/lib/pkgconfig" to the
- PKG_CONFIG_PATH environment variable.
-
- There are a number of configure options. See the output of
- configure when run with the --help command line option.
-
-2) If all goes well with the above then compiling the library can be
- done with
-
- make
-
-3) When that has finished, the test suite can be run using:
-
- make check
-
-4) The final step is to install the library. This step needs to be
- carried out as the root user (or with sudo):
-
- make install
-
- This command will by default install the library in the directory
- /usr/local/lib. It can in installed in other location by using the
- --prefix option in step 1).
-
-5) On linux, one more step is required, the registering of the library
- with the system. This is done by running the following command
- (also as the root user):
-
- ldconfig -v
-
-As a final test, you can run
-
- sndfile-resample
-
-to make sure everything is installed correctly.

-# These exist entirely to fool aclocal when bootstrapping libtool.
-#
-# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),
-# which have later been changed to m4_define as they aren't part of the
-# exported API, or moved to Autoconf or Automake where they belong.
-#
-# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
-# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
-# using a macro with the same name in our local m4/libtool.m4 it'll
-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)
-#
-# So we provide this file, which has a silly filename so it's always
-# included after everything else. This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
-#
-# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
-# Yes, that means every name once taken will need to remain here until
-# we give up compatibility with versions before 1.7, at which point

-This is libsamplerate, 0.1.9
-
-libsamplerate (also known as Secret Rabbit Code) is a library for
-perfroming sample rate conversion of audio data.
-
-The src/ directory contains the source code for library itself.
-
-The doc/ directory contains the libsamplerate documentation.
-
-The examples/ directory contains examples of how to write code using
-libsamplerate.
-
-The tests/ directory contains programs which link against
-libsamplerate and test its functionality.
-
-The Win32/ directory contains files and documentation to allow
-libsamplerate to compile under Win32 with the Microsoft Visual C++
-compiler.
-
-Win32
------
-There are detailed instructions for building libsamplerate on Win32
-in the file
-
- doc/win32.html
-
-
-MacOSX
-------
-Building on MacOSX should be the same as building it on any other
-Unix.
-
-
-OTHER PLATFORMS
----------------
-To compile libsamplerate on platforms which have a Bourne Shell compatible
-shell, an ANSI C compiler and a make utility should require no more that
-the following three commands :
- ./configure
- make
- make install
-
-CONTACTS
---------
-
-libsamplerate was written by Erik de Castro Lopo (erikd AT mega-nerd DOT com).
-The libsamplerate home page is at :

-<P>
-The publically callable functions of libsamplerate are all listed in the
-<B><samplerate.h></B> header file.
-In order to use any of the functionality of libsamplerate, you need to add
-</P>
-<PRE>
- #include <samplerate.h>
-</PRE>
-<P>
-to the top of any function that call any of the following functions.
-You will also need to link you binary with the libsamplerate library.
-</P>
-<P>
-The API allows three methods for accessing the capabilies of the library:
-</P>
-<UL>
- <LI>A <A HREF="api_simple.html">simple interface</A> which can sample rate convert
- a single block of samples (one or more channels) in one go.
- The simple API is less capable than the full API.
- <LI>A <A HREF="api_full.html">more fully featured interface</A> which allows time
- varying sample rate conversion on streaming data (again one or more
- channels).
- <LI>A <A HREF="api_callback.html">callback interface</A> which has the same
- functionality as the interface above but allows the details of input and
- output to be separated.
- The output is generated by call a read function and the library calls a user
- supplied callback function to obtain its input.
- This interface is particularly well suited to applications where the output
- sample rate is varied with time.
-</UL>
-
-<P>
-<b>NB :</b> All three access methods are able to process multi channel interleaved
-data.
-</P>
-
-<P>
-The parts of the API which are common to all three interfaces are:
-</P>
-<UL>
- <LI> The <A HREF="api_misc.html#ErrorReporting">error reporting</A> mechanisim.
- <LI> The available <A HREF="api_misc.html#Converters">converter</A> types.
- <LI> The <A HREF="api_misc.html#SRC_DATA">SRC_DATA</A> struct.
-</UL>
-<P>
-All three versions of the API are restricted to operating on buffers of ISO C
-Standard <B>float</B> data.
-However, there are two
- <A HREF="api_misc.html#Aux">auxillary functions</A>
-for converting arrays of float data to and from short data.
-</P>
-
-<P>
-<B>Note:</B> The <B>tests/</B> and <B>examples/</B> directories of the source code
-distribution contain numerous example programs showing the use of the library.

-Most of the API functions either return an integer error (ie <B>src_simple</B>
-and <B>src_process</B>) or return an integer error value via an int pointer
-parameter (<B>src_new</B>).
-These integer error values can be converted into a human readable text strings by

-</P>
-<PRE>
- const char* src_strerror (int error) ;
-</PRE>
-<P>
-which will return an error string for valid error numbers, the string "No Error"
-for an error value of zero or a NULL pointer if no error message has been defined
-for that error value.
-</P>
-
-<A NAME="Converters"></A>
-<H3><BR>Converters</H3>
-<P>
-Secret Rabbit Code has a number of different converters which can be selected
-using the <B>converter_type</B> parameter when calling <B>src_simple</B> or
-<b>src_new</B>.
-Currently, the five converters available are:
-</P>
-<PRE>
- enum
- {
- SRC_SINC_BEST_QUALITY = 0,
- SRC_SINC_MEDIUM_QUALITY = 1,
- SRC_SINC_FASTEST = 2,
- SRC_ZERO_ORDER_HOLD = 3,
- SRC_LINEAR = 4
- } ;
-</PRE>
-<P>
-As new converters are added, they will given a number corresponding to the
-next inetger.
-</P>
-
-<P>
-The details of these converters are as follows:
-</P>
-<UL>
- <LI> <B>SRC_SINC_BEST_QUALITY</B> - This is a bandlimited interpolator derived
- from the mathematical <B>sinc</B> function and this is the highest
- quality sinc based converter, providing a worst case Signal-to-Noise
- Ratio (SNR) of 97 decibels (dB) at a bandwidth of 97%.
- All three SRC_SINC_* converters are based on the techniques of
- <A HREF="http://ccrma-www.stanford.edu/~jos/resample/">Julius O. Smith</A>
- although this code was developed independantly.
- <LI> <B>SRC_SINC_MEDIUM_QUALITY</B> - This is another bandlimited interpolator
- much like the previous one. It has an SNR of 97dB and a bandwidth of 90%.
- The speed of the conversion is much faster than the previous one.
- <LI> <B>SRC_SINC_FASTEST</B> - This is the fastest bandlimited interpolator and
- has an SNR of 97dB and a bandwidth of 80%.
- <LI><B>SRC_ZERO_ORDER_HOLD</B> - A Zero Order Hold converter (interpolated value
- is equal to the last value). The quality is poor but the conversion speed is
- blindlingly fast.
- <li><b>SRC_LINEAR</b> - A linear converter. Again the quality is poor, but the
- conversion speed is blindingly fast.
-</UL>
-<P>
-There are two functions that give either a (text string) name or description
-for each converter:
-</P>
-<PRE>
- const char *src_get_name (int converter_type) ;
- const char *src_get_description (int converter_type) ;
-</PRE>
-<P>
-The name will typically be a short string for use in a dialog box, while the
-description string is longer.
-</P>
-<P>
-Both of these functions return a NULL pointer if there is no converter for the
-given <B>converter_type</B> value.
-Since the converters have consecutive <B>converter_type</B> values, the caller
-is easily able to figure out the number of converters at run time.
-This enables a binary dynamically linked against an old version of the library
-to know about converters from later versions of the library as they become
-available.
-</P>
-
-<A NAME="SRC_DATA"></A>
-<H3><BR>SRC_DATA</H3>
-<P>
-Both the simple and the full featured versions of the API use the <B>SRC_DATA</B>
-struct to pass audio and control data into the sample rate converter.
-This struct is defined as:
-</P>
-<PRE>
- typedef struct
- { float *data_in, *data_out ;
-
- long input_frames, output_frames ;
- long input_frames_used, output_frames_gen ;
-
- int end_of_input ;
-
- double src_ratio ;
- } SRC_DATA ;
-</PRE>
-<P>
-The <B>data_in</B> pointer is used to pass audio data into the converter while the
-<B>data_out</B> pointer supplies the converter with an array to hold the converter's
-output.
-For a converter which has been configured for mulitchannel operation, these pointers
-need to point to a single array of interleaved data.
-</P>
-<P>
-The <B>input_frames</B> and <B>output_frames</B> fields supply the converter with
-the lengths of the arrays (in frames) pointed to by the <B>data_in</B> and
-<b>data_out</B> pointers respectively.
-For monophinc data, these values would indicate the length of the arrays while
-for multi channel data these values would be equal to the the length of the array
-divided by the number of channels.
-</P>
-
-<P>
-The <B>end_of_input</B> field is only used when the sample rate converter is used
-by calling the <B>src_process</B> function.
-In this case it should be set to zero if more buffers are to be passed to the
-converter and 1 if the current buffer is the last.
-</P>
-<P>
-Finally, the <B>src_ratio</B> field specifies the conversion ratio defined as
-the input sample rate divided by the output sample rate.
-For a connected set of buffers, this value can be varies on each call to
-<B>src_process</B> resulting in a time varying sample rate conversion
-process.
-For time varying sample rate conversions, the ratio will be linearly
-interpolated between the <B>src_ratio</B> value of the previous call
-to <B>src_process</B> and the value for the current call.
-</P>
-<P>
-The <B>input_frames_used</B> and <B>output_frames_gen</B> fields are set by the
-converter to inform the caller of the number of frames consumed from the
-<B>data_in</B> array and the number of frames generated in the <B>data_out</B>
-array respectively.
-These values are for the current call to <B>src_process</B> only.

-<P>
-<B>Important Note:</B>
-The simple API is not designed to work on small chunks of a larger piece of
-audio.
-If you attempt to use it this way you are doing it wrong and will not get the
-results you want.
-For processing audio data in chunks you <b>must</b> use the
- <a href="api_full.html">full api</a>
-or the
- <a href="api_callback.html">callback based api</a>.
-</P>
-
-<br/><br/>
-
-<P>
-The simple API consists of a single function :
-</P>
-<PRE>
- int src_simple (SRC_DATA *data, int converter_type, int channels) ;
-</PRE>
-<P>
-The use of this function rather than the more fully featured API requires the caller
-to know the total length of the input data before hand and that all input and output
-data can be held in the system's memory at once.
-It also assumes that there is a single constant ratio between input and output sample
-rates.
-<!--
-If these conditions cannot be met, the full featured API should be used instead.
-In addition, this documentation is complemented by this
-<A HREF="ex_simple.html">example code</A>. -->
-</P>
-
-<P>
-Dealing with the easy stuff first, the <B>converter_type</B> parameter should be
-one of the values defined in <B>samplerate.h</B> and documented
-<A HREF="api_misc.html#Converters">here</A> while the <b>channels</b> parameter
-specifies the number of interleaved channels that the sample rate converter
-is being asked to process (number of input channels and output channels is always
-equal).
-There is no hard upper limit on the number of channels; it is limited purely
-by the amount of memory available.
-</P>
-
-
-<P>
-The first parameter to <B>src_simple</B> is a pointer to an <B>SRC_DATA</B> struct
-(more info <A HREF="api_misc.html#SRC_DATA">here</A>) defined as follows:
-</P>
-<PRE>
- typedef struct

-<H2><BR><B>Q1 : Is it normal for the output of libsamplerate to be louder
- than its input?</B></H2>
-<P>
-The output of libsamplerate will be roughly the same volume as the input.
-However, even if the input is strictly in the range (-1.0, 1.0), it is still
-possible for the output to contain peak values outside this range.
-</P>
-<P>
-Consider four consecutive samples of [0.5 0.999 0.999 0.5].
-If we are up sampling by a factor of two we need to insert samples between
-each of the existing samples.
-Its pretty obvious then, that the sample between the two 0.999 values should
-and will be bigger than 0.999.
-</P>
-<P>
-This means that anyone using libsamplerate should normalize its output before
-doing things like saving the audio to a 16 bit WAV file.
-</P>

-<h2><br><b>Q2 : On Unix/Linux/MacOSX, what is the best way of detecting
- the presence and location of libsamplerate and its header file using
- autoconf?</b></h2>
-
-<p>
-libsamplerate uses the pkg-config (man pkg-config) method of registering itself
-with the host system.
-The best way of detecting its presence is using something like this in configure.ac
-(or configure.in):
-</p>
-
-<pre>
- PKG_CHECK_MODULES(SAMPLERATE, samplerate >= 0.1.3,
- ac_cv_samplerate=1, ac_cv_samplerate=0)
-
- AC_DEFINE_UNQUOTED([HAVE_SAMPLERATE],${ac_cv_samplerate},
- [Set to 1 if you have libsamplerate.])
-
- AC_SUBST(SAMPLERATE_CFLAGS)
- AC_SUBST(SAMPLERATE_LIBS)
-</pre>
-<p>
-This will automatically set the <b>SAMPLERATE_CFLAGS</b> and <b>SAMPLERATE_LIBS</b>
-variables which can be used in Makefile.am or Makefile.in like this:
-</p>
-<pre>
- SAMPLERATE_CFLAGS = @SAMPLERATE_CFLAGS@
- SAMPLERATE_LIBS = @SAMPLERATE_LIBS@
-</pre>
-
-<p>
-If you install libsamplerate from source, you will probably need to set the
-<b>PKG_CONFIG_PATH</b> environment variable's suggested at the end of the
-libsamplerate configure process. For instance on my system I get this:
-</p>
-<pre>
- -=-=-=-=-=-=-=-=-=-= Configuration Complete =-=-=-=-=-=-=-=-=-=-=-
-
- Configuration summary :
-
- Version : ..................... 0.1.3
- Enable debugging : ............ no
-
- Tools :
-
- Compiler is GCC : ............. yes
- GCC major version : ........... 3
-
- Extra tools required for testing and examples :
-
- Have FFTW : ................... yes
- Have libsndfile : ............. yes
- Have libefence : .............. no
-
- Installation directories :

-<H2><BR><B>Q3 : If I upsample and downsample to the original rate, for
- example 44.1->96->44.1, do I get an identical signal as the one before the
- up/down resampling?</B></H2>
-<P>
-The short answer is that for the general case, no, you don't.
-The long answer is that for some signals, with some converters, you will
-get very, very close.
-</P>
-<P>
-In order to resample correctly (ie using the <B>SRC_SINC_*</B> converters),
-filtering needs to be applied, regardless of whether its upsampling or
-downsampling.
-This filter needs to attenuate all frequencies above 0.5 times the minimum of
-the source and destination sample rate (call this fshmin).
-Since the filter needed to achieve full attenuation at this point, it has to
-start rolling off a some frequency below this point.
-It is this rolloff of the very highest frequencies which causes some of the
-loss.
-</P>
-<P>
-The other factor is that the filter itself can introduce transient artifacts
-which causes the output to be different to the input.
-</P>

-<CENTER><P>

-<P>
- When measuring the performance of a Sample Rate Converter, there are three
- factors to consider:
-</P>
-<UL>
- <LI><B>Signal-to-Noise Ratio</B> - a measure of how much noise the sample
- rate conversion process adds to the signal.
- This is measured in decibels (dB) and the higher this value the
- better.
- For most sample rate converters, the SNR will vary depending on
- the input signal and the ratio between input and output sample
- rates.
- The only valid comparison of SNR is between the worst case for
- for each converter.
- <LI><B>Bandwidth</B> - most sample rate converters attenuate high
- frequencies as part of their operation.
- Bandwidth can be measured by finding the frequency where the
- attenuation is 3dB and expressing that as a percentage of the full
- bandwidth at that sampling rate.
- <LI><B>Speed</B> - the faster the better <B>:-)</B>.
-</UL>
-
-<P>
- There are a number of sample rate converters available for downloading
- but I will limit the comparison ot Secret Rabbit Code to the following:
-</P>
-<UL>
- <LI><A HREF="http://www.mega-nerd.com/SRC/download.html">sndfile-resample</A>
- which is a program (which uses libsamplerate) from the <B>examples/</B>
- directory of the Secret Rabbit Code source code distribution.
- <LI><A HREF="http://www-ccrma.stanford.edu/~jos/resample/Available_Software.html">
- Resample</A>
- by Julius O Smiths which seems to have been the first high quality converter
- available as source code.
- <LI><A HREF="http://www.tsp.ece.mcgill.ca/MMSP/Documents/Software/AFsp/ResampAudio.html">ResampAudio</A>
- which is part of
- <A HREF="http://www.tsp.ece.mcgill.ca/MMSP/Documents/Software/AFsp/AFsp.html">
- Audio File Programs and Routines</A>
- by Peter Kabal.
- <LI><A HREF="http://home.sprynet.com/~cbagwell/sox.html">SoX</A> which is maintained
- by Chris Bagwell.
- SoX is also able to perform some low quality sample rate conversions but these
- will not be investigated.
- <LI><A HREF="http://shibatch.sourceforge.net/">Shibatch</A> which seems to be a
- frequency domain sample rate converter.
- Unfortunately, this converter does not handle arbitrary conversion ratios and
- hence could not be properly compared to the other converters.
- <LI><A HREF="http://sr-convert.sourceforge.net/">sr-convert</A> is another
- converter which does not handle arbitrary conversion ratios.
-</UL>
-
-<P>
-It should be noted that the first three converters above are based on the algorithm
-by <A HREF="http://www-ccrma.stanford.edu/~jos/resample/"> Julius O. Smith</A>
-which emulates the conversion of the digital signal to an analogue one and then
-sampling the analogue signal at the new sample rate.
-</P>
-
-<!--+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++-->
-
-<H3><B>Methodology</B></H3>
-<P>
- Measuring the SNR of a converter is relatively straight forward.
- Generate an input signal consisting of a windowed sine wave, sample rate
- convert it and measure the signal-to-noise ratio of the output signal.
- A typical length for the original file is 30000 samples.
-</P>
-<P>
- The bandwidth of a sample rate converter is a little more difficult to measure.
- Currently this is done by generating two short files containing a windowed
- sine wave.
- The frequencies of the sine waves are 0.35 and 0.495 of the sample rate.
- These file are then upsampled by a factor of 2 using the converter under test.
- If the attenutaion of the lower frquency is less than 3dB and higher frequency is
- more than 3dB, it is then possible to iteratively increase the lower frequency
- and decrease the upper frequency keeping the -3dB point bracketed.
- When the distance between the upper and lower frequency is sufficiently small,
- it is possible to obtain a very accurate estimate of the -3dB frequency.
-</P>
-<P>
- The speed of a sample rate converter is easy to measure; simply perform a
- conversion on a large file or a number of smaller files and time the conversion
- process.
-</P>
-
-<P>
- The above measurement techniques are built into a test program which is delivered
- with the Secret Rabbit Code source code distibution.
- This program is able to test the first four of the above converters.
-</P>
-<!--+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++-->
-
-<H3><B>SoX</B></H3>
-<P>
- SoX provides three methods of resampling; a linear interpolator, a polyphase
- resampler and the Julius O. Smith simulated analogue filter method.
-</P>
-
-<H3><B>Shibatch</B></H3>
-<P>
- Shibach

- <B>More Coming Soon.</B>

-<H1><B>Compiling on Win32.</B></H1>
-<P>
-For Win32 there is a Microsoft Visual C++ compatible makefile in the <B>Win32\</B>
-directory and a MSDOS batch file in the top level directory of the distribution.
-</P>
-<P>
-To build the examples programs you will need to download the precompiled
-win32 or win64
- <A HREF="http://www.mega-nerd.com/libsndfile/#Download">libsndfile</A>
-binary and install them.
-
-</P>
-<P>
-Making the libsamplerate DLL on Win32 involves the following:
-</P>
-<OL>
- <LI> Using WinZip in the GUI, open the libsamplerate-0.X.Y.tar.gz file and
- extract the files into a directory. The following example assumes
- <B>C:\</B>.
- <LI> In the directory containing the extracted files, find the file
- <B>Win32\Makefile.msvc</B> and open it in a text editor (ie Notepad or
- similar).
- <LI> Find the line which starts with <B>MSVCDir</B> and modify the directory
- path to point to the location of MSVC++ on your machine. This allows the
- makefile to inform the compiler of the location of the standard header
- files.
- <LI> Copy <B>libsndfile-1.dll</B>, <B>libsndfile-1.lib</B> and
- <B>libsndfile-1.def</B> from the directory libsndfile was installed in
- to the the directory containing libsamplerate.
- <LI> Copy the header file <B>include/sndfile.h</B> from where libsndfile was
- installed to the <B>Win32</B> directory under the libsamplerate
- directory.
- <LI> Open a Command Shell and cd into the libsamplerate-0.X.Y directory.
- <LI> Make sure that the program <B>nmake</B> (which is part of the MSCV++
- package) is in a directory which is part of your <B>PATH</B> variable.
- <LI> Type in the command
- <PRE> C:\libsamplerate-0.X.Y> make
- </PRE>
- and press <return>. You should now see a a large number of compile
- commands as libsamplerate.dll is built.
- <LI> To check that the built DLL has been compiled correctly type in and run the
- command
- <PRE> C:\libsamplerate-0.X.Y> make check
- </PRE>
- which will compile a set of test programs and run them.
- If any of the programs fail the error message will be help in debugging
- the problem.
- (Note that some of the tests require libsndfile or libfftw/librfftw and
- are not able to run on Win32).
-</OL>
-<P>
-At the end of the above procedure, you will find the DLL, <B>libsamplerate.dll</B>, a
-LIB file <B>libsamplerate.lib</B> in the current directory. These two files, along
-with the header file <B>samplerate.h</B> (in the <B>src\</B> directory) are all that
-you need to copy to your project in order to use libsamplerate.
-</P>
-
-<H2><BR>Compile Problems</H2>
-<P>
-If you run into compile problems using the above procedure, you should
- <A HREF="lists.html"> join the main mailing list </A>
-and post your problem and/or questions there.
-Please include any error messages generated during step 6 above.
-</P>
-
-<P>
-If you are using some other method to compile the libsamplerate DLL you are
-probably on your own.
-</P>

-/*============================================================================
-** On Intel Pentium processors (especially PIII and probably P4), converting
-** from float to int is very slow. To meet the C specs, the code produced by
-** most C compilers targeting Pentium needs to change the FPU rounding mode
-** before the float to int conversion is performed.
-**
-** Changing the FPU rounding mode causes the FPU pipeline to be flushed. It
-** is this flushing of the pipeline which is so slow.
-**
-** Fortunately the ISO C99 specifications define the functions lrint, lrintf,
-** llrint and llrintf which fix this problem as a side effect.
-**
-** On Unix-like systems, the configure process should have detected the
-** presence of these functions. If they weren't found we have to replace them
-** here with a standard C cast.
-*/

-** long int lrintf (float x) ;
