No they aren't. Well, I should say that's not entirely correct. The
simplest 8 bit format is straight 8 bit data. There is the option to
save as u-Law, A-Law, ADPCM, and a host of other formats, but what
Microsoft call PCM is straight out of the ADC.
Calling it PCM is a bit of a misnomer anyway. While it's in the file,
it's 8 bit (parallel) data.

between them. I needed a long, continuous recording.
