- Hello:
-
- I am not sure I agree with you. For me your ideia has the same
- problem as tape to tape copy: noise problems. What really is needed
- is decoding the tape, and do a program to save again the thing in the
- tape, generating signal afresh. Someone wishes to comment that?
-
- I am developing now a Spectrum emulation, and I have been developing
- a short program to decode Spectrum's tapes and write the binary contents in
- .TAP files (shorter than .WAV files, of course). It still got its flaws
- (especialy with tape noise), but it's working. I am planing of releasing it
- as GNU or something like that, if there people out there interested in
- 'fidling' with the program... (PC assembler sources).
-
- I have also read here in the conference that a guy wrote one
- utility to save Spectrum's tapes...
