1. The CPC464 and CPC464+ have a cassette player built in. To connect a cassette player to the CPC664, CPC6128 or KC Compact then you must use a lead.
2. It is not known exactly how the amplitude of the sound from the cassette corresponds to the final "0" or "1" measurement.
samp2cdt uses a crude method to perform this conversion.
For a 8-bit signed sample:
* if the amplitude is 0..127, then the final measurement will be "1".
* if the amplitude is -128..0 then the final measurement will be "0".
