Info about cassettein about epple-ii

It's the duration of the cycle that matters, not the strength. The most accurate way I could come up with is what's documented in that source file... looking for the change in slope between positive/negative to indicate the beginning of a cycle. But it's still hit or miss with analog data. I also did some work on processing cassette input with Apple-II-Cassette-Recover, which tries to build a clean wav file. It looks at the input cycle lengths and decides which of the known expected durations it's closest to. It's still not perfect. I ran many tests of real wav files from cassettes, and some worked, but some didn't.

Eventually I figured out how to process all formats from https://asciiexpress.net/ but I admit my code will probably struggle with a real analogue input.

There's a large collection of analog captures at Brutal Deluxe. I remember trying many of those, and some worked in Epple II, but some didn't. I'd be interested if your code could handle these. Where is your code? In AppleWin?
