I have quite a bit of software on cassette tapes for 1980s home computers. Does anyone know of a simple method (without having to design and build myself a dual-tone decoder circuit + write suitable PC software) of getting this information onto a PC? I guess the home computer emulator pages on the web must have done this. Maybe I could record it as a WAV file then write a program to decode the WAV? Or would MP3 encoding be capable of compressing and reliable expanding the audio data (MP3 is of course designed to compress music which these squeaks and whistles clearly are not, even if they lie within the audio spectrum!). paul
