[[Audio::mp3]]

Audio codec 2: 'Audio codec' is part of the LAME project, which is the source code for a fully GPL'd MP3 encoder. The project's goal is to improve the psychoacoustics, noise shaping and speed of MP3.

Av-caster: From the project's README on 29 October 2021: AvCaster is built upon the JUCE framework, utilizing gStreamer as the media backend and libircclient as the chat backend. It is currently capable of recording to file or streaming to an RTMP server with screen capture (full-screen), webcam (full-screen or overlay), and audio (mono or stereo). It is moderately configurable, with preset configurations for streaming via popular servers such as livecoding.tv, and allows custom user-defined configurations to be stored as additional presets. This initial target is GNU/Linux, but it has been designed for portability and includes starter projects for AndroidStudio, CodeBlocks, VisualStudio, and xCode IDEs.

Biblos: 'Biblos' is a powerful indexing tool for managing a cd/mp3 collection as well as local directories. It records full information about each file on the specified media and has a powerful searching tool that can help you find specific files. You can also select a list of files/dirs from the database and Biblos will help you copy them from the source media to the directory choosen.

BurnCDDA: 'burnCDDA' is a console frontend to cdrdao, cdrecord, mpg123, oggdec, mppdec, normalize, and mp3_check. It can be used to create audio CDs from an M3U playlist (the playlist format of XMMS). It supports MP3, OGG Vorbis, Musepack, and WAV files, and it might be the easiest way to copy an audio CD.

Cantus: 'Cantus' is a tool for tagging and renaming MP3 and OGG/Vorbis files. Its features include mass tagging and renaming of MP3s, the ability to generate a tag out of the filename, filter definitions for renaming, recursive actions, CDDB (Freedb) lookup (no CD needed), the ability to copy between ID3V1 and ID3V2 tags, and more.

Cmus: cmus (C* Music Player) is a small, fast and powerful console audio player for Unix-like operating systems. It supports almost all common file formats, SHOUTcast/Icecast streaming, and multiple output plugins. cmus features multiple media library views, a playqueue, a directory browser, powerful filters, and vi-style search and keybindings. The text-only design reduces the resources needed to run the program, making it a strong choice for older or less-powerful computers as well as systems where a graphical environment is not available.

Cutmp3: 'cutmp3' is a small command line MP3 editor. It lets you select sections of an MP3 interactively or via a timetable and save them to separate files without quality loss. Silence and ID3 tag searching are also possible. For playback it uses mpg123. The program works with VBR files and files bigger than 2GB.
