Well Ive found that AudioTap/WavPrg works a treat for immediately converting T64 files into WAVs
But what do the guys on the Sinclair Newsgroup use? Would be a fag to have to play all the Speccy TAP files in full to convert them into a WAV...
On the Amstrad front I see Kevin Thacker has written a Sample to CDT program, hopefully he might have an idea on a reverse engineering program
