You can do this on a *.tap file. The C2N232 connects directly to the digital read/write lines on the cassette port. When I worked on the tape routines, I typed SAVE and was a bit surprised to see how much the pulse widths varied. The C2N232 will hopefully generate cleaner frequencies. I also wrote a PCM output option for my "c2n" program and tested it by recording the audio to a cassette and loading it with a 1530. One more thing that I seem to remember doing is that I connected the C2N232 to the digital lines from a 1530 to sample the tapes.
