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.

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.

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.

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.

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.

JAAD is an open-source AAC decoder and MP4 demultiplexer library written completely in Java. It is platform-independent and portable.

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.

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.

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

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

Java decoder for FLAC sound files, small but efficient to operate either stand-alone or within javax.sound.sampled SPI environment. This project updates the historic jFLAC package 1.5.2 to enhance features. The package can now convert FLAC to PCM-streams of any format with exception of the sample-rate. The package binary format is in Java 8 for maximum compatibility. The status is: operative and tested.

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

Pure Java MP3 Encoder. Easy-to-use java tool and Ideal solution for a built-in MP3 encoder library. Supported source formats: - WAVE_FORMAT_PCM - WAVE_FORMAT_IEEE_FLOAT 32bit per sample only

Unicode Rewriter is a Java tool which converts ID3 tags of MP3 files into Unicode. The reconverted MP3 files can be processed by iTunes and Rhythmbox.

The Universal Batch Converter is a project to take all the myriad file conversion programs, and provide a powerful but easy to use interface for all types of file conversion.

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.

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.

The Java based Shoutcast-Icecast Stream Grabber supports recording of up to 10 simultaneous streams. It enables you to record a complete song even when you notice in the middle of the song that you like it and supports track separation using meta data.

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.

Implementation of the WSOLA algorithm for time scale modification of audio without artifact introduction (ideally). It allows one to speed/slow audio without altering its pitch.

A utility that can modify wav files to change the playing time of an audio clip, and transpose or scale the pitch of the clip. Great for audio book enthusiasts, and music lovers. Time shifting. DSP. Pitch Scaling.
