- A simple build system.
- It should Just Work out of the box, without the need to download and install any dependencies.
- A simple API.
- Supports both playback and capture on all backends.
- Supports playback, capture and full-duplex.
- Data conversion.
- Sample format conversion, with optional dithering.
- Sample rate conversion.
