Free wav software for linux

Gwav2ogg is a front-end to the ever popular Ogg encoder console application.

Gwav2ogg is written in the GTK toolkit.

I wrote it because I like my audio files in the .ogg format verses the wav format. Please feel free to send me any comments/questions/suggestions/better website.

aifc2wav is an aifc (ima4, sowt or sdx2) to wav translator.

I made this little piece of software, because I wanted to listen to some khoomei music (23 Jul 2005: link appears to be dead), and some of those AIFC files were not handled by sox, nor xmms, nor mplayer. Those files were in AIFC IMA4 format.

How to use it?

Unzip the C file with gunzip.

You will need a C compiler (gcc is fine). Simply compile it (for instance gcc -o aifc2wav aifc2wav-4.c), and you are done.

It handles AIFC IMA4 files, AIFC SOWT files and AIFC SDX2 files, both mono and stereo (not sure for SDX2). The SOWT scheme has not been widely tested, if your file sounds strange, contact me. (Same for SDX2.)

It will produce a WAV file. Why WAV? Because WAV files are handled by almost everyone. If you want raw data, you can skip the 44 bytes long header (something like dd if=INPUT_FILE of=OUTPUT_FILE bs=44 skip=1 under unix). Or use sox, which is a good program.

It is supposed to work on any machine, little/big endian. The only problem that might appear is because of this silly 80 bits extended float used by those silly coders. Who needs that much precision for a frequency? Well, so they did, so they did. I dont know if I handle this correctly or not.

WavTools is a set of WAV file processing programs for Unix.

The tools included are are:

wavcat - Concatenates WAV files, with options to convert stereo to mono.
wavpad - Adds padding to 16 bit 44 kHz WAV files, as required by some CD writing software.
wavinfo - Displays information from the header and chunks of a WAV file.

Edit the Makefile to choose build options and installation
directories.

Type "make" to build the library, programs, and documentation. Type "make install" to install the programs and manual pages.

Wavsilence takes a large WAV file with gaps of silence and create smaller WAV files, containing the data between the gaps. This is done based on length and tolerance parameters, which are used to determine what qualifies as silence. The original way of using it was to split up the chapters of large audio book files.

Development and testing is performed on an x86 machine running RedHat 9, using gcc-3.x. Although testing has not been performed on other platforms, wavsilence should run on any UNIX machine, and possibly on Windows. If you succeed in using wavsilence on another platform, please let me know.

Increasing the sample buffer can *really* increase the throughput of the program. On a dual 933MHz P3 with 256MB RAM and an ATA100 IDE disk, a sample buffer of 64 provides optimal performance (~6MB/s). Id like to hear about performance others are getting.

Enabling the progress display (the -p option) may reduce performance if you have a fast system.

When piping output to a command (the -P option), the throughput is limited to the speed at which the command youre running can take data. If you have the space, it would be faster to let the program create the pieces in separate files (the default behavior) and then
use the "-e" option to exec a program on each file when its done.

JaWavedit is a WAV file editor written in Java. It runs on every operating system that supports Java.
Main features:
- loading/saving of any .wav/.au files
- playing, looping, winding
- display the wave in any zoom
- change frequency, balance and volume while playing
- handle any frequency in 8 and 16 bit
- a fancy and functional look
- speaking 3 languages (English, Deutsch and Francais)
- a module concept, which allows to extend me
- the open standard giving you the oppertunity to write your own modules
- making me just as well a development platform for any kind of audio processing

FLAC is a lossless compression method for audio files. Using it, one is able to reduce the filesize and keep the same audio quality as a regular WAV file (CD quality).

The FLAC format is open source, and can be read without any problem by such applications as Amarok or Kaffeine.

Wav and Flac conversion contains two service menus: one to convert WAV files into FLAC, and one to convert FLAC files into WAV.

You will need the FLAC application to be installed on your system to use these service menus.

GBAconv is a set of tools aimed at GameBoy Advance developers. GBAconv allows you to convert WAV sounds and PCX images into C arrays to be included in GBA programs.

It is composed of two programs:

- pcx2gba: exports a PCX 8-bpp image to 16-bit values C arrays: palette + image data (2 pixels per value)
- wav2gba: exports a WAV 8-bit mono sound to 8-bit signed values array.

There wont be any other releases of GBAconv, as Ive no interest for the GBA platform anymore.

Compiling:

Simply type "make" to compile the program.

It has been successfully compiled on:

- 32-bit x86 Architecture (Ubuntu Linux 5.10, FreeBSD 5.4)

Usage:

pcx2gba input.pcx output.inc array_name (Input File must be 8-bit PCX)
wav2gba input.wav output.inc array_name (Input File must be 8-bit, MONO)
