These will probably make up the "standard" PCM prop names to use. i.e.

  "channels" - The number of channels. Usually 1 or 2.
  "rate" - The sample rate. 44100 or 48000 for example.
  "bitsPerSample" - The bitdepth of one sample for 1 channel of audio.
                    8 for 8-bit, 16 for 16-bit, etc.
  "float" - if true, then the PCM samples are "floats"
