Instructions for WAV2HP48,

Send the *.wav file to your calc, (or EMU48), and press 'CONV' to
convert the string into Library Data. Next, enter a binary number, like
#101b, to set the timing. The bigger the binary number, the slower the
speed. Now press 'PLAY'. The sound quality pretty much sucks, but I
like to record myself playing guitar, and then play it through the calc,
(it comes through perfectly distorted).

I use EMU48 to open the *.wav file and 'CONV' it on the computer because
most *.wav files are larger than 128k.
