  The virtual MIME type for decoded mono PCM audio — the intermediate between an
  audio container and a transcription. Bytes are little-endian Float32 samples
  in `[-1, 1]`; a [`ConvertOutput`](https://adk.nht.io/api/@nhtio/adk/batteries/media/contracts/interfaces/ConvertOutput) carrying PCM must set `meta.sampleRate`
  (Hz).
