irrKlang is a high level 2D and 3D cross platform sound engine and audio library that plays WAV, MP3, OGG, MOD, XM, IT, S3M, and other file formats. It can be used by C++ and all .NET languages (C#, Visual Basic.NET, etc.). It has all of the features common to low-level audio libraries as well as lots of useful features like a sophisticated streaming engine, extendable audio reading, single and multi-threading modes, 3D audio emulation for low-end hardware, a plugin system, multiple rolloff models, sound effects, and more. All of these can be accessed via an extremely simple API using an object oriented design.
somaplayer is music player for MP3, Ogg, wav, audio CDs, MP3 streams, and Ogg streams. It is able to use the appropriate sound drivers or demons or to stream directly to an Icecast server (Icecast2 or SHOUTcast) or to encode in MP3 and Ogg Vorbis. It also acts as a sound daemon that is able to accept connections from other somaplayers or any other sound player (xmms, mpg123, and others) thanks to a special wrapper.
StreamBOX-LiveCD is a KNOPPIX-based boot CD which is specially designed to stream MP3s. It also includes some programs to stream in the Ogg Vorbis format, to cut audio, to view video and video streams, and to perform other similar tasks. It is intended to be used at smaller radio stations.
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.
Traktor DJ Studio is a powerful and versatile software solution for professional DJ mixing, live remixing, and mix recording using tracks in MP3, WAV, AIFF and CDDA format. It exceeds the possibilities of traditional DJ equipment by implementing a vast range of mixing features that only software can provide. This includes graphic waveform displays, tempo recognition and automatic synchronization, up to 10 cue points and 10 tempo-precise loops per track, and a track database with an ultra-fast search function.
SBAM (Software Based Abled Mixer) is a new approach to computer-based DJing.. This project aims to help DJs concentrate on the important aspects of DJing and to decrease the stress factor. It is intended for the DJs that have no need for beatmixing or other advanced mixing techniques, which means you'll be limited when it comes to creative individual mixing of tracks. Instead, you'll be able to concentrate on finding the right track for the audience.
MP3 STATION is a LIRC-aware, plain-text tool set for managing MP3 playback in a car or home with as little user interaction as possible. It can restart the last playlist at the last played track/frame, transparently load directories, transparently recompile playlists, and keep a repository of all the playlists. It also has two simple clients for communicating with cm3s (a curses console client and a very basic one on a parallel port). All programs run under a non-privileged user account.
