A streaming audio player for iOS and OS X.


  • CPU-friendly design (uses 1% of CPU on average when streaming)
  • Multiple protocols supported: ShoutCast, standard HTTP, local files
  • Prepared for tough network conditions: adjustable buffer sizes, stream pre-buffering and restart on failures
  • Metadata support: ShoutCast metadata, IDv2 tags
  • Local disk caching: user only needs to stream a file once and after that it can be played from a local cache
  • Preloading: playback can start immediately without needing to wait for buffering
  • Record: support recording the stream contents to a file
  • Access the PCM audio samples: as an example, a visualizer is included

Is somebody using this in real life?

The short answer is yes! Check out our website for the reference applications.
