Open Source ChromeOS 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.

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.

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.

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.

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.

KurzFiler is a software for editing the files of the Kurzweil sampler series. It is mainly intended for users of these great instruments.

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.

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

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.

This application allows you to convert all Windows Media Player Playlists .wpl inside a choosen directory to m3u <-> Convierte todos los playlists .wpl de Windows Media Player que están dentro de un directorio seleccionado en playlists m3u.

Converts a toc generated by cdrdao (or similar) to a .cue as known from tools like EAC. Works only for CD_DA toc.

ALCHEMIST is a Korg Trinity to Triton PCG and SNG converter. KORGLIB is a set of C libraries to access Trinity, Triton and Z1 PCG/SNG data.

Clean implementation (in ANSI-C) of the Wavelets Transform. It works fairy good as a sparser, which can be combined with a compression algorithm (by using programs like bzip and gzip) to achieve high compression ratios (as good as mp3's).

WavPack is a free, fast, flexible and featureful encoder and decoder for audio streams. Besides lossless, it can perform lossy and hybrid (lossy+correction file) encodings.

Audio a Midi bajo octave. Solo soporta wav, pero pretendo que acepte otros. Quiero prepararlo para polifonía. <p>Audio to Midi converter, under octave, it only supports wav, but I pretend it to accept another files. I want to improve it to polyphonic.

Creates printable covers for your (mp3) CD/DVDs. Creates a LaTeX file with front and back covers listing of artistnames, albumnames and songnames by examining the directory structure and the MP3 tags. The output PS/PDF can then be printed easily.

QAudioCoder is a Qt library for decoding and encoding raw audio samples. The library also provides functionality to directly decode or encode audio files and convert between different formats. Currently only WAVE, MP3 and FLAC formats are supported.

XMedia is an XML framework to manage a large collection of media files like CDR, Images, Video, MP3, etc. XMedia does for media what DocBook does for documentation. See http://xmedia.sourceforge.net/

A sound enhancing plugin. It's primary goal is to enhance sound of mp3 files, especially compressed in not optimal manner. Crystality consists of bandwidth extender(aka exciter), harmonic booster, rather nice echo and an ordinary stereo extender.

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.

Command line tool handling steps to clean, calibrate, process, mix, master and deliver music tracks from recordings. Easy-to-use configuration files drive the complete processes.

".ECW file" or "waveset" refers to a file with an extension of ".ECW" which stores articulation and sample data used by the MIDI synthesizer of sound cards equipped with an ES1370, ES1371, or ES1373 chip. These sound cards include the Ensoniq AudioPCI, the Sound Blaster! AudioPCI, the Sound Blaster! PCI64, the Sound Blaster! PCI128, and the Sound Blaster Live!. This project is a Perl script which can unpack these files into a .WAV sample, and a corresponding .SFZ file (an open format used by various sample engines to describe sample playback.)

mp3 to ogg format converter. This is a suite of programs which will help you to convert your existing mp3 files into ogg. The suite includes a text and a graphical frontend. Requires mpg321, mp3info, oggenc, vorbiscomment (zenity for gui).
