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!

microenc is a small Bash shell script for Linux/BSD for encoding directories with audio files to other formats using FFmpeg as encoder.

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. You can submit pull requests via GitHub: https://github.com/knik0/faac https://github.com/knik0/faad2

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.

Tom's Audio Processing plugins is a selection of LADSPA plugins for audio engineering on the Linux platform. Intended for use in a professional DAW environment such as Ardour, it includes high quality reverberation, echo, eq, limiter & more.

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.

This de-esser uses a novel approach called Temporal Sibilance Processing. The idea is to distinguish between fricatives and voiced sections of the speech signal by the number of zero crossings in time. Most of the speech file is left untouched (the samples are directly copied from source to destination). Only fricatives that are long enough and loud enough are filtered. The advantage of this approach over traditional approaches is that the clarity of the remaining speech is completely unaffected.

MP3 Recoder allows users to convert audio files into lower bit rates, saving a marginally lower quality copy on an MP3 player and leaving the original file unchanged. It can create the file name on the MP3 player from the source file to circumvent limitations of MP3 players and to organize the target files. Existing metadata can be used for this purpose (MP3 files: ID3 tags, OGG vorbis: comments). See also the web site (link below).

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.

Mpadec is a high-quality portable MPEG audio decoder library. It supports MPEG-1, MPEG-2 Layer I, Layer II and Layer III audio streams, including free-format streams.

using voip technology and java technology to provide user with free and good quality communication around the world

mp32ogg is a PHP based mp3 to ogg batch (mass) converter, which supports relative quality and copies ID3 tags.

sr-convert is a command-line sample-rate converter for WAV files, which supports a wide variety of sampling rates, and achieves very high sound quality. It runs on Windows (MinGW) and x86 Linux systems, and makes use of SSE instructions if available.

OpenShiiva is a simple yet powerful vob to mp4 converter, featuring an all YUV pipeline, and with high quality in mind. Converts video -and- audio at the same time.

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.

Midi2ogg is a shell-based frontend to TiMidity++ and Oggenc that allows the user to convert a midi or mod file to Ogg Vorbis at the desired quality level with a very simple command syntax.

A Front-End for many common MP3/OGG creation tools. Can be configured to create many variants of quality MP3/OGG files easily and reliably.
