Open Source BSD Audio Conversion Software

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.

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.

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.

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.

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.

It can also extract audio from the following video extensions: RM, RV, ASF, DivX, MPG, MKV, MPEG, AVI, MOV, OGM, OGV, QT, VCD, SVCD, M4V, NSV, NUV, PSP, SMK, VOB, FLV, WEBM and WMV. Parallel Processing, a CD ripping function with CDDB support, batch conversion, tag preservation for most supported formats, independent tag reading & writing, service menus for KDE Dolphin/Konqueror, Gnome Nautilus script, and action scripts for Nemo/Thunar are also provided.

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.

MPC Maid ("MM") is a software editor for the Akai MPC 500, MPC 1000, and MPC 2500. It is Mac, PC, and Linux-compliant and makes the edition of MPC programs files easy. It also features a semi-automatic slicing tool to chop loops into slices.

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.

Audio player, transcoder and cd ripper for Mac OS X, Windows, Unix, and Linux. Plays and creates ogg, flac, mp3, aac, m4a, mp4, wav, and aif, and plays wma. 31-band equalizer, repeat loop, variable pitch/tempo, ram or ramdisk preload, more.

Python Audio Tools are a collection of audio handling programs. These include programs for CD extraction, track conversion from one audio format to another, track renaming and retagging, track identification, CD burning from tracks, and more.

EnDiskEx is a command-line tool that bulk extracts instruments, sequences, songs, and banks from Ensoniq-formatted disk images (RAW, GKH, EDE, and EDA) for the EPS/ASR family of samplers. The extracted files are saved as EFE / SMF / TXT files. EnDiskEx is designed to extract Ensoniq banks for re-creation within a different DAW. It will track down the instrument and song files from bank references even if they were saved on another disk. There also exists a disk mapping feature to correct for any errors in this process caused by having relabeled disks, forgotten to label disks, etc. EnDiskEx has been tested and validated against a variety of RAW, GKH, EDE, and EDA images files the dev team has, including but not limited to, the ASR factory disks, the EPS 16+ factory disks, and the EPS (classic) factory disks.

ReZound aims to be a stable, open source, and graphical audio file editor primarily for but not limited to the GNU/Linux operating system.
