I never understood how high speed duplication worked, or was supposed to
work. Cassette tapes have a very limited frequency response as it is,
thus it seems to me that at higher speeds a lot of the audio content
would be sent to the recording head at higher frequencies than either it
or the tape itself were designed to handle.
