It natively supports MP3, WMA and M4A files.

Helium Streamer uses HTML5 audio playback by default, if the browser supports it. If the browser does not support your file format it will reply on an Adobe Flash component.

It is also able to transcode (convert on-the-fly) files from the following formats:

  • FLAC (*.flac) 
  • Ogg Vorbis (*.ogg) 
  • Monkey's Audio (*.ape) 
  • WAVE (*.wave, *.wav) 
  • WacPack (*.wv, *.wvc) 
  • AAC (*.aac) 

Playing these file formats is fully automated and requires no extra configuration.
