- Unlimited number of mono, stereo or multichannel (up to 32 channels) input and output pins.
- From 8 to 32 bits per mono audio sample for any input and output stream.
- Unlimited mixing flexibility: any channel from an input pin can be mixed to any channel of an output pin with user-defined bit depth.
- Dynamic range compression to eliminate volume overflow (more information on Wikipedia).
- Seeking support.
Future Extentions
- Resampling (connections with different audio frequencies will be allowed).
