I am very excited to hear about the progress that is being made towards Audio loading for the FIGnition. Of course this gets me to start thinking about where I have stored those C15 tapes! and what to use to play and record to them with.
With my Spectrum, I have used a utility called tap2wav, this does what it says on the tin converts tap files to audio wav files, therefore would it be correct to assume that recording the output to a wav file and replaying it from your phone or player would be suitable enough?
The mp3, I have read, are not deep enough to convey data.
The audio files could then just be downloaded and loaded with a homemade lead 3.5mm to RCA
