Mp3blaster is an interactive text-based program that plays several audio file types (MP3, Ogg Vorbis, wav, and sid). It is one of the few audio players for the text console that allows full interactive control during playback. One of its key features is the ability to compose a very flexible playlist (while playing!). It plays most MP3 formats and has full mixer support built in.
OpenAL, the Open Audio Library, is a joint effort to create an open, vendor-neutral, cross-platform API for interactive, primarily spatialized audio. Its primary audience is made up of application developers and desktop users that rely on portable standards like OpenGL for games and other multimedia applications.
MoreAmp is an audio player, transcoder, and CD ripper for Mac OS X, Mac OS 9, Windows, Unix, and Linux. It plays and creates ogg, flac, mp3, aac, m4a, mp4, wav, and aif files, and plays wma files. It features a 31-band equalizer, repeat loop, variable pitch/tempo, ram or ramdisk preload, and more.
PhonoRipper is an easy to use, all-in-one GUI tool for creating audio CDs from analog sources like vinyl records. It uses Cdrdao for CD writing and Normalize for volume normalization. Features include a fully buffered WAV file recorder with mixer and VU meter (supporting both ALSA and OSS drivers), automatic detection of track borders, an intuitive drag'n'drop CD writing interface with CD-text support, CDDB queries of CD text data, and a WYSIWYG CD cover editor.
The GNU Compact Disc Input and Control library encapsulates CD-ROM reading and control for applications wishing to be oblivious to the OS- and device-dependent properties of a CD-ROM. It provides an API for access to SCSI-MMC (multimedia commands) and support for CD image types like BIN/CUE, cdrdao's TOC, and Nero's NRG, which gives applications using the library the ability to read disc images as though they were CDs. ISO-9660 filesystem support is included, as are utility programs for displaying CD and CD-ROM drive information, reading the blocks of a CD, and extracting files from an ISO-9660 filesytem image. cdparanoia is also included.
aRts is a framework for developing modular multimedia applications. The sound server, artsd, allows multiple applications to cooperatively process and output sound and music. aRts is designed to provide its filter and synthesis capabilities to other applications using the multimedia communication protocol (MCOP). aRts is also capable of modular realtime synthesis. It can create sounds & music (realtime midi synthesis) using small modules like oscillators for creating waveforms, various filters, mixers, faders, etc.
Festival is a general multi-lingual speech synthesis system developed at CSTR. It offers a full text to speech system with various APIs, as well an environment for development and research of speech synthesis techniques. It is written in C++ with a Scheme-based command interpreter for general control.
