An audio CD has a sampling frequency of 44100 Hz, much more than the bandwidth of a C cassette. 44100 Hz is 22 clock cycles on the PAL C64, 23 on NTSC. It could be possible to use e.g. a 4:5 GCR coding with a bit rate of 22050 Hz, which gives a byte rate of 2205 bytes per second. That is much more than TurboTape can ever achieve. Even 44100 bit/s would be theoretically possible if the "cassette read" input was edge-sensitive on both falling and rising edges. Maybe it is at least on some Commodores.
