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.
KOssMixer allows a user to control the hardware mixer of a sound card. It self-adjusts to the available mixer controls provided by the user's hardware and driver combination. KOssMixer provides a few unusual features not found in other mixers, including the ability to hide unused mixer controls and to rename controls to reflect their usage rather than be constrained to the generic name provided by the driver.
SDLucid is a C++ wrapper library for the SDL media library. It aims to not only be a wrapper, but to also offer a cleaner interface than the original SDL, as well as increased functionality. This additional functionality includes fonts, PNG loading, graphical primitives, built-in mixing, mod playing, and MP3 decoding. SDLucid follows naming conventions, approximating those of the Standard Template Library.
Mixxx is software for DJs that provides everything needed to create live mixes. It allows you to beatmatch songs and crossfade them together, like you would with turntables and a mixer. It runs without any extra hardware, and offers a wide range of advanced features including comprehensive MIDI controller and vinyl control support. To obtain the lowest latency and highest responsiveness, it uses hardware video acceleration and takes advantage of multi-core CPUs.
kamix is a mixer for KDE and ALSA, with more features than kmix (or at least with more features than kmix had when kamix was started). It supports channel splitting, levels storing/restoring, sync with external ALSA events, correct handling of "enumerated" elements, and selective item hiding/showing.
