Hugh,

In the double speed process, the tape is played back at double speed, but
the recorder also samples at double speed, such that when the recording is
played back at the normal sample rate, the audio plays back at its original
correct speed, so speed and formants are unchanged.

Due to the high speed playback, there is some minor loss of fidelity, and
also some minor EQ issues, but for speech, these are often welcomed
tradeoffs for the reduced transfer time.
