Libsndfile is a C library for reading and writing files containing sampled sound
|
|
(such as MS Windows WAV and the Apple/SGI AIFF format) through one standard
|
|
library interface. It is released in source code format under the
|
|
<A HREF="http://www.gnu.org/copyleft/lesser.html">Gnu Lesser General Public License</A>.
|
|
</P>
|
|
<!-- pepper -->
|
|
<P>
|
|
The library was written to compile and run on a Linux system but should compile
|
|
and run on just about any Unix (including MacOS X).
|
|
There are also pre-compiled binaries available for 32 and 64 bit windows.
|
|
</P>
|
|
<P>
|
|
It was designed to handle both little-endian (such as WAV) and big-endian
|
|
(such as AIFF) data, and to compile and run correctly on little-endian (such as Intel
|
|
and DEC/Compaq Alpha) processor systems as well as big-endian processor systems such
|
|
as Motorola 68k, Power PC, MIPS and Sparc.
|
|
Hopefully the design of the library will also make it easy to extend for reading and
|
|
writing new sound file formats.
|
|
</P>
|
|
<!-- pepper -->
|
|
<P>
|
|
It has been compiled and tested (at one time or another) on the following systems:
|
|
</P>
|
|

libsndfile has the following main features :
|
|
</P>
|
|
<UL>
|
|
<lI> Ability to read and write a large number of file formats.
|
|
<LI> A simple, elegant and easy to use Applications Programming Interface.
|
|
<LI> Usable on Unix, Win32, MacOS and others.
|
|
<LI> On the fly format conversion, including endian-ness swapping, type conversion
|
|
and bitwidth scaling.
|
|
<LI> Optional normalisation when reading floating point data from files containing
|
|
integer data.
|
|
<LI> Ability to open files in read/write mode.
|
|
<LI> The ability to write the file header without closing the file (only on files
|
|
open for write or read/write).
|
|
<LI> Ability to query the library about all supported formats and retrieve text
|
|
strings describing each format.
|
|
</UL>
|
|
<P>
|
|
libsndfile has a comprehensive test suite so that each release is as bug free
|
|
as possible.
|
|
When new bugs are found, new tests are added to the test suite to ensure that
|
|
these bugs don't creep back into the code.
|
|
When new features are added, tests are added to the test suite to make sure that
|
|
these features continue to work correctly even when they are old features.
|
|
</P>
|
|
<P>
|
|
The following table lists the file formats and encodings that libsndfile can read
|
|
and write.
|
|
The file formats are arranged across the top and encodings along the left
|
|
edge.

I have decided that I will not be adding support for MPEG Layer 3 (commonly

known as MP3) due to the patent issues surrounding this file format.

<A NAME="History"></A>

<H1><B>History</B></H1>
|

<P>
|
|
My first attempt at reading and writing WAV files was in 1990 or so under Windows
|
|
3.1.
|
|
I started using Linux in early 1995 and contributed some code to the
|
|
<A HREF="http://www.vaxxine.com/ve3wwg/gnuwave.html">wavplay</A>
|
|
program.
|
|
That contributed code would eventually mutate into this library.
|
|
As one of my interests is Digital Signal Processing (DSP) I decided that as well as
|
|
reading data from an audio file in the native format (typically 16 bit short integers)
|
|
it would also be useful to be able to have the library do the conversion to floating
|
|
point numbers for DSP applications.
|
|
It then dawned on me that whatever file format (anything from 8 bit unsigned chars,
|
|
to 32 bit floating point numbers) the library should be able to convert the data to
|
|
whatever format the library user wishes to use it in.
|
|
For example, in a sound playback program, the library caller typically wants the sound
|
|
data in 16 bit short integers to dump into a sound card even though the data in the
|
|
file may be 32 bit floating point numbers (ie Microsoft's WAVE_FORMAT_IEEE_FLOAT
|
|
format).
|
|
Another example would be someone doing speech recognition research who has recorded
|
|
some speech as a 16 bit WAV file but wants to process it as double precision floating
|
|
point numbers.

libsndfile is released under the terms of the GNU Lesser General Public License,
|
|
of which there are two versions;
|
|
<a href="http://www.gnu.org/licenses/old-licenses/lgpl-2.1.html">version 2.1</a>
|
|
and
|
|
<a href="http://www.gnu.org/copyleft/lesser.html">version 3</a>.
|
|
To maximise the compatibility of libsndfile, the user may choose to use libsndfile
|
|
under either of the above two licenses.
|
|
You can also read a simple explanation of the ideas behind the GPL and the LGPL
|
|
<A HREF="http://www.gnu.org/copyleft/copyleft.html">here</A>.
|

|

<P>
|
|
You can use libsndfile with
|
|
<A HREF="http://www.gnu.org/">Free Software</A>,
|
|
<A HREF="http://www.opensource.org/">Open Source</A>,
|
|
proprietary, shareware or other closed source applications as long as libsndfile
|
|
is used as a dynamically loaded library and you abide by a small number of other
|
|
conditions (read the LGPL for more info).
|
|
With applications released under the GNU GPL you can also use libsndfile statically
|
|
linked to your application.
|
|
</P>
|
|
<P>
|
|
I would like to see libsndfile used as widely as possible but I would prefer it
|
|
if you released software that uses libsndfile as
|
|
<A HREF="http://www.gnu.org/">Free Software</A>
|
|
or
|
|
<A HREF="http://www.opensource.org/">Open Source</A>.
|
|
However, if you put in a great deal of effort building a significant application
|
|
which simply uses libsndfile for file I/O, then I have no problem with you releasing
|
|
that as closed source and charging as much money as you want for it as long as you
|
|
abide by <A HREF="http://www.gnu.org/copyleft/lesser.html">the license</A>.
