Open Source C Audio Conversion Software

SoX is the Swiss Army Knife of sound processing utilities. It can convert audio files to other popular audio file types and also apply sound effects and filters during the conversion.

LAME is an educational tool to be used for learning about MP3 encoding. The goal of the LAME project is to improve the psycho acoustics, quality and speed of MP3 encoding. Note: we provide source code only!

The SoX Resampler library `libsoxr' performs one-dimensional sample-rate conversion—it may be used, for example, to resample PCM-encoded audio. It aims to give fast and high quality results for any constant (rational or irrational) resampling ratio. Phase-response, preserved bandwidth, aliasing, and rejection level parameters are all configurable; alternatively, simple `preset' configurations may be selected. An experimental, variable-rate resampling mode of operation is also included.

Create data discs with advanced data settings. Create video and audio discs, Burn will convert if needed. Create DVD-Video discs. Recreate discs. Burn doesn't reinvent the wheel, it uses many powerful open source Unix utilities and is also open source.

The Bauer stereophonic-to-binaural DSP (bs2b) library and plugins is designed to improve headphone listening of stereo audio records. Recommended for headphone prolonged listening to disable superstereo fatigue without essential distortions.

MAD is a high-quality fixed-point MPEG audio decoder with 24-bit output. The implementation is entirely new, based on the ISO/IEC standards, and performs especially well on systems without native floating-point support.

mp3splt is a free utility to split mp3, ogg vorbis and FLAC files without decoding, selecting begin/end time; if file is an album, you can get splitpoints automatically from internet or a local cue, cddb file. It also splits Mp3Wrap and AlbumWrap archives. Supports splitting and trimming by silence detection. For mp3 files, both ID3v1 and ID3v2 are supported using original tags or user defined tags.

FLAC is a free lossless compressed audio format which supports streaming and archival. The FLAC project maintains the format and provides a reference encoder/decoder and input plugins for several popular audio players.

Lossless compressor for multichannel 8,16 and 24 bits audio data, with the ability of password data protection. Being 'lossless' means that no data/quality is lost in the compression - when uncompressed, the data will be identical to the original.

fre:ac is a free audio converter and CD ripper for various formats and encoders. It features MP3, MP4/M4A, WMA, Ogg Vorbis, FLAC, AAC, and Bonk format support, integrates freedb/CDDB, CDText and ID3v2 tagging and is available in several languages.

Multimedia architecture consisting of libraries and applications. Libraries include gavl for low level audio/video support and gmerlin_avdecoder, a multiformat decoding library. Applications include a GUI player with mediatree and a GUI transcoder.

LSP (Linux Studio Plugins) is a collection of open-source plugins currently compatible with LADSPA, LV2 and LinuxVST formats. Standalone plugins for JACK are provided since version 1.0.8. Experimental support of ARMv7 added since version 1.1.4 Experimental support of AArch64 added since version 1.1.9 Decomposition of modules and new UI introduced in 1.2.0 Added CLAP support in 1.2.5 Added VST3 support in 1.2.15 The basic idea is to fill the lack of good and useful plugins under the GNU/Linux platform. After some contributions to other open source projects the decision was made to implement separate and independent plugin distribution.

PlayerPro is a music composer and sound editor ( SoundTracker ) for MOD S3M XM IT UMX . Uses XI, Quicktime or SoundFonts. Currently runs on MacOS and OSX; playback engines also available for Windows and BeOS. Upcoming version 6 will support ALSA (Linux).

A/52 audio encoder. Creates stereo and multi-channel audio streams.

mpg321 is a completely Free drop-in replacement for mpg123. It has been designed to work as a drop-in replacement for mpg123, for the use of front ends, shell scripts, etc. It does all mp3 decoding using the high-quality integer-only MAD library.

mp3wrap is a free indipendent alternative to AlbumWrap. It's a command-line utility that wraps quickly two or more mp3 files in one single large playable mp3, without losing filenames and ID3 informations. To split original files use mp3splt.

Transcoder Audio Edition is an audio converter for Linux which can convert from one audio format into another and can extract audio tracks from video files and convert them into audio formats. It uses GTK+ as GUI toolkit and ffmpeg as backend.

TooLAME is an optimized MPEG Audio Layer 2 encoder.

libTiMidity is a MIDI to WAVE converter library that uses Gravis Ultrasound-compatible patch files to generate digital audio data from General MIDI files. This library based on the TiMidity decoder from SDL_sound library.

Winamp MP3 output plugin based on LAME. Now you can encode your MP3 files directly from Winamp.

Flake is an open-source FLAC audio encoder.

IMYplay is a player for iMelody (IMY) ringtones / files (https://en.wikipedia.org/wiki/IMelody). IMYplay can use the following outputs to produce sound: 1. The Allegro game library (http://alleg.sf.net), 2. SDL (Simple DirectMedia Layer; http://www.libsdl.org), 3. ALSA (Advanced Linux Sound Architecture; http://alsa-project.org), 4. OSS (Open Sound System), 5. Libao (http://xiph.org/ao), 6. PortAudiov19 (http://www.portaudio.com), 7. PulseAudio (http://www.pulseaudio.org), 8. JACK1/JACK2 (http://jackaudio.org), 9. GStreamer (http://gstreamer.freedesktop.org), 10. PC-Speaker (at least Linux and DOS). It can also: - convert IMY ringtones to MIDI files, - convert IMY ringtones to WAV files, - write raw samples to an output file, - execute an external program on each note. See the project homepage https://imyplay.sourceforge.io and the project Wiki in the menu above.

WildMidi is a midi processing library and a midi player using the gus patch set.

Mp3 decoder to convert mp3 files into wav file. Works well on Linux, Windows and Android. Can perform fast fourier transforms on decoded audio data. Under research & development by WeaveBytes

Game audio/data format extraction/conversion/injection tool/media player. Supports over 43 Xbox1/Xbox360/PC formats.
