Because some of these hearing can last a long
time, and to conserve audio tapes, they record them at half-speed. My
attorney needs to hear this tape and be able to understand it, but at the
current speed, it just sounds like Alvin and the Chipmunks on meth...

Maybe someone at the appeals court can help you. After all they must have
machines that work at half speed so they can listen to the tapes and make
notes from them. It shouldn't me too difficult to connect one of these
machines to a conventional cassette recorder and re-record the tape.

Remember that if you increase the speed of an analogue tape you increase the
pitch. If you re-record this tape digitally and slow it down digitally the
voices will still be high pitched, and may be difficult to recognise, unless
you have a program that can pitch down the voices digitally.

If someone has a 1/4" tape machine they could record the session at one
speed and then replay it at half that speed to give you what you want (eg.
record at 3 3/4"/sec and replay at 1 7/8"/sec).
