AlsaPlayer – heavily multi-threaded PCM player

AlsaPlayer is a type of PCM player. It is heavily multi-threaded and tries to excercise the ALSA library and driver quite a bit.

It has some very interesting features unique to Linux/Unix players. The goal is to create a fully pluggable framework for playback of all sorts of media with the focus on PCM audio data.

This is free and open source software.

Features include:

• Full speed (pitch) control, positive *and* negative. This is the first Linux and only GPL player that supports this. You can scratch mp3’s and even audio CD’s in realtime.
• Icecast/shoutcast streaming support.
• Interface plugins.
• Completely redefine the user interface.
• Remote control.
• Control alsaplayer from another application.
• Low latency mode.
• On capable soundcards latency can be as low as 1.3ms.
• Playlist/Queue support.
• Plays nice with concurrent audio tools.
• Doesn’t touch the hardware mixer.
• Concurrent visual scopes.
  Open as many scopes as there are.
• Multi-threaded design – this results in efficient/skip free playback. You can also activate real-time scheduling for even better performance..
• Accurate scope/audio syncing.
• Portable.
