For the output section its performance is dictated by many factors of the accompanying cassette recorder such as its input impedance and its input gain section.
For example, many mic inputs are high impedance and high gain and line inputs are low impedance and low gain.
Ahh. Well I didn't have any luck when trying to load WAV samples from a digital recorder. Same ones that I made for CM. So I thought maybe that would help.
It could read the header, I assume ... I would try load"" or load"turtle" ... I would see it print TURTLE M ... then nothing as the WAV file finished. I eventually realised that the last character meant B for BASIC and M for machine code.
So if it could read the filename at the volume I set, then I assume it should've been able to read the rest of the sample. I did try various volume settings on the digital recorder.
Of course, I could be using the entirely wrong command to load - I didn't bother reading the manual.
Okay, command should be okay ... it says I can used LOAD? to also verify checksums, so maybe I'll try that too.
I did make an LPF I'd read about that included a speaker - I might try hooking that up - I'm guessing it was remove 50Hz hum from the tape player or something?
Reading further ... ouch, harsh!
This option should only be used as a desperation measure when you have been foolish enough not to dump two copies when SAVEing and then verify the first one.
