The libsndfile Modules for GNU Octave
=====================================
These modules are currently known to work with version 3.0 of GNU Octave on
Linux. They have not been tested elsewhere.
Build Requirements
------------------
In order to build these libsndfile related modules for GNU Octave on a Debian
GNU/Linux (or Debian derived) system, you will need (on top of what is normally
required to build libsndfile) the package:
octaveX.Y-headers
where X.Y matches the version number of your installation of GNU Octave.
The configure script in the top level libsndfile directory will detect the
presence and correct versions of the Octave build tools. The building of these
modules will only go ahead if everything is correct.

# libsndfile
libsndfile is a C library for reading and writing files containing sampled audio
data.
## Hacking
The canonical source code repository for libsndfile is at
[https://github.com/erikd/libsndfile/][github].
You can grab the source code using:
$ git clone git://github.com/erikd/libsndfile.git
Building on Linux, OSX and Windows (Using GNU GCC) will require a number of GNU
and other Free and Open Source Software tools including:
* [Autoconf][autoconf]
* [Autogen][autogen]
* [Automake][automake]
* [Libtool][libtool]
* [Pkgconfig][pkgconfig]
* [Python][python]
If you are on Linux, its probably best to install these via your Linux
distribution's package manager.
If you want to compile libsndfile with support for formats like FLAC and
Ogg/Vorbis you will also need to install the following optional libraries:
* [FLAC][flac]
* [libogg][libogg]
* [libvorbis][libvorbis]
Support for these extra libraries is an all or nothing affair. Unless all of
them are installed none of them will be supported.
$ ./autogen.sh
Running `autogen.sh` also installs a git pre-commit hook. The pre-commit hook
is run each time a user tries to commit and checks code about to be committed
against coding guidelines.
Nest step is to run configure, with the following configure options being
recommended for anyone contemplating sending libsndfile patches:
$ ./configure --enable-gcc-werror
Finally libsndfile can be built and tested:
$ make
$ make check
## Submitting Patches.
* Patches should pass all pre-commit hook tests.
* Patches should always be submitted via a either Github "pull request" or a
via emailed patches created using "git format-patch".
* Patches for new features should include tests and documentation.
* Patches to fix bugs should either pass all tests, or modify the tests in some
sane way.
* When a new feature is added for a particular file format and that feature
makes sense for other formats, then it should also be implemented for one
or two of the other formats.

When you configure and compile libsndfile, it uses the /bin/sh shell for a number
of tasks (ie configure script and libtool).
Older versions of OSX (10.2?) shipped a a really crappy Bourne shell as /bin/sh

Dear libsndfile user,
</p>
<!-- pepper -->
<p>
This library was developed on Linux for Linux. I am not a Windows user and
maintaining this library for Windows costs me significant amounts of time above
and beyond the time taken to make it work on Linux and Unix-like systems.
</p>
<!-- pepper -->
<p>
I therefore ask Windows users of libsndfile to donate to ensure that libsndfile's
support for Windows continues. As long as donations continue to flow in at a decent
rate, I will continue to release precompiled Windows binaries in sync with the
Linux/Unix version. If donations are poor, support for windows will fall behind.
</p>
<!-- pepper -->
<p>
You are free to donate any amount you chose.
As a guideline:
</p>
<!-- pepper -->
<ul>
<li>If you are simply a user of libsndfile that would like to ensure that
the development of libsndfile continues, a donation of $10US would be more
than adequate.
</li>
<li>If you are shareware author that distributes libsndfile with your app and
makes more than $1000 a year from your shareware, a one off donation of $50
would be appropriate.
</li>
<li>If your company is a commercial software house that distributes one or more
products that ship with libsndfile, a donation of $100 every second or third
year would be appropriate.
</li>
</ul>
<!-- pepper -->
<p>
Donations can be made in Bitcoin to the Bitcoin address

and run on just about any Unix (including MacOSX).
It can also be compiled and run on Win32 systems using the Microsoft compiler and
MacOS (OS9 and earlier) using the Metrowerks compiler.
There are directions for compiling libsndfile on these platforms in the Win32 and
MacOS directories of the source code distribution.

Date: Tue, 20 Jul 2004 22:49:21 +0100
Hi,
I'm trying to get the source examples in the "Programming Linux Games"
(NoStarch, Loki Software + John R. Hall) which use sndfile.h/libsndfile.
While I can guess some of the newer versions of function calls and
enumerations, there are some which I cannot guess.
Would you be able to translate them to the current version of
enumeration and function calls so that I can update the source?
These are the three currently failing me:
sf_open_read(filename, SF_INFO *sfinfo) (guess: sf_open(filename,SFM_READ, &sfinfo))
SF_FORMAT_PCM (guess: either SF_FORMAT_PCM_U8 or _RAW)
SF_INFO.pcmbitwidth (guess: no idea!)
There are probably more. I'm happy to send you the source files for
sound calls, scan the pages or anything else. Failing that, is there
somewhere with the changes listed so I can try and fix the code for myself?
Thanks
TTFN
Paul

Actually this list:
SF_FORMAT_PCM_U8
SF_FORMAT_PCM_S8
SF_FORMAT_PCM_16
SF_FORMAT_PCM_24
SF_FORMAT_PCM_32
> SF_INFO.pcmbitwidth (guess: no idea!)
WIth the above change, pcmbitwidth becomes redundant.

Version 1.0.0 came out some time ago, but I think this:
http://www.mega-nerd.com/libsndfile/version-1.html
lists most of the changes. You should also look at the API docs:

I know, but the source code explicitly has SF_FORMAT_PCM which given the
code afterwards would equate to one of the above, but given that PCM
files can have a varied bitwidth the author probably wanted to cover all
bases.

But surely the existing code does something like:
sfinfo.format = SF_FORMAT_WAV | SF_FORMAT_PCM;
sfinfo.pcmbitwidth = 16;
which can be directly translated to:
sfinfo.format = SF_FORMAT_WAV | SF_FORMAT_PCM_16;
and the same for pcmbitwitdhs of 24 and 32. For pcmbitwidth of 8
you need to know that WAV files use SF_FORMAT_PCM_U8 and AIFF
files use SF_FORMAT_PCM_S8. Thats all there is to it.

If only!
The actual code is this
int LoadSoundFile(char *filename, sound_p sound)
{
SNDFILE *file;
SF_INFO file_info;
short *buffer_short = NULL;
u_int8_t *buffer_8 = NULL;

sf_close(file);

}
if ((file_info.pcmbitwidth == 8) && (file_info.channels == 1)) {

sound->format = AL_FORMAT_STEREO8;
} else if ((file_info.pcmbitwidth == 16) && (file_info.channels == 1)) {
sound->format = AL_FORMAT_MONO16;
} else if ((file_info.pcmbitwidth == 16) && (file_info.channels == 2)) {
sound->format = AL_FORMAT_STEREO16;
} else {
printf("Unknown sample format in %s.\n", filename);
sf_close(file);
return -1;
}
/* Allocate buffers. */
buffer_short = (short *)malloc(file_info.samples * file_info.channels * sizeof (short));
buffer_8 = (u_int8_t *)malloc(file_info.samples * file_info.channels * file_info.pcmbitwidth / 8);
buffer_16 = (int16_t *)buffer_8;
if (buffer_short == NULL || buffer_8 == NULL) {
printf("Unable to allocate enough memory for '%s'.\n", filename);
goto error_cleanup;
}
/* Read the entire sound file. */
if (sf_readf_short(file,buffer_short,file_info.samples) == (size_t)-1) {
printf("Error while reading samples from '%s'.\n", filename);
goto error_cleanup;
}
<minor snip>
/* Fill in the sound data structure. */
sound->freq = file_info.samplerate;
sound->size = file_info.samples * file_info.channels * file_info.pcmbitwidth / 8;
/* Give our sound data to OpenAL. */
alGenBuffers(1, &sound->name);
if (alGetError() != AL_NO_ERROR) {
printf("Error creating an AL buffer name for %s.\n", filename);
goto error_cleanup;
}

goto error_cleanup;
}
/* Close the file and return success. */
sf_close(file);
free(buffer_short);
free(buffer_8);
return 0;
error_cleanup:
if (file != NULL) fclose(file);
free(buffer_short);
free(buffer_8);
return -1;
}
As you can see, the PCM material in the listing will not currently
compile and for the other sndfile material, it probably won't either.
Any help would be appreciated.

From version 1.0.0 libsndfile has had the ability to read and write files of
greater than 2 Gig in size on most OSes even if sizeof (long) == 4.
OSes which support this feature include Linux (2.4 kernel, glibc6) on x86, PPC and
probably others, Win32, MacOSX, *BSD, Solaris and probably others.

**
** How to use:

**
** - You must edit this file to point to the file you want to convert. Set
** the following line of code (found in the Main() function further below)
** to the name of a .WAV file that exists on your system.
** 186: string sfn = "input.wav";
**
** - From a command prompt type
** csc generate.cs
**
** - Run the resulting executable 'generate.exe'
**
**
** Note: You will obviously need the csc compiler and the .NET runtime. I think
** these are freely available for download from Microsoft's website
** (part of the .NET SDK?).

sndfile-regtest
===============
The 'sndfile-regtest' program is a regression test-suite for libsndile.
This program is intended to allow anyone who has an interest in the
reliability and correctness of libsndfile to do their own regression
testing. From the point of view of the libsndfile developers, this
program now allows for distributed regression testing of libsndfile
which will make libsndfile better.
How Does it Work
----------------
Anyone who wishes to take part in the distributed regression testing of
libsndfile can download the regression test program and install it.
Once installed the user can start collecting files and adding them to
their own personal database. Then, as new versions of libsndfile come
out, the user should test the new library version against their database
of files (instructions below).
Any files which were successfully added to the database in the past but
now fail the check with the new library version represent a regression.
The user should then contact the libsndfile developers so that a copy
of the test file can be made available to the developers.
Requirements
------------
The regression test program uses sqlite3 as the database engine. On
Debian, the required packages are :
sqlite3
libsqlite3-0
libsqlite3-dev
but similar packages should be available on any other Linux style
system.
The regression test currently only compiles under Unix-like systems.
At some time in the future the regression test will distributed along
with the libsndfile source code distribution.
Organization of Files
---------------------
The regession test program keeps its database file in the directory it
is run from. In addition, the database only contains information about
the files, not the files themselves.
This means that database file should probably be kept in the same
directory (or a directory above) the test files.
Setting it Up for the First Time
--------------------------------
The sndfile-regtest program should be on your PATH. You can then cd into
the directory where you intend to keep you test files and
run the command:
sndfile-regtest --create-db
which creates a file named '.sndfile-regtest.db' in the current directory.
Files can then be added to the database using the command:
sndfile-regtest --add-file file1.wav
The --add-file option allows more than one file to be added at a time
using:
sndfile-regtest --add-file file1.wav file2.aif .....
Checking Files
--------------
One or more files that have already been added to the database can be
checked using:
sndfile-regtest --check-file file1.wav file2.aif .....
It is also possible to check all files in the database using:
sndfile-regtest --check-all
Running a Regression Test
-------------------------
Once you have a collection of files and a database it is possible to test
new versions of libsndfile before you install them. If for instance you
have just compiled a new version of libsndfile in the directory
/usr/src/libsndfile-X.Y.Z, then you can use an existing sndfile-regtest
binary with the new libsndfile using something like:
LD_PRELOAD=/usr/src/libsndfile-X.Y.Z/src/.libs/libsndfile.so.X.Y.Z \
sndfile-regtest --check-all
Reporting Regressions
---------------------
Any user who finds a file which was added to the regression database with
an earlier version of libsndfile and then fails the check with a later
version of the library should contact the author (erikd at mega dash nerd
dot com). If possible place the file on a web server and email the author
a link to it.
