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!

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 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.

FAAC is an Advanced Audio Coder (MPEG2-AAC, MPEG4-AAC). The goal of FAAC is to explore the possibilities of AAC and exceed the quality of the currently best MP3 encoders.

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.

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.

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.

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.

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.

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

PSID64 is a program that converts PSID and RSID files into C64 executables. This allows users to play PSID and RSID files (originally used by the PlaySID program) on a real Commodore 64 computer or emulator such as VICE.

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

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.

NorQualizer is a smart audio equalizer/normalizer which corrects audio files to get them all similar in terms of bandwidth and volume level. Especially useful for preparing audio CDs with files from different sources.

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.
