Great that you're working on something similar! How are you finding those tools for handling degraded tape waveforms? I keep bouncing back and forth between hacking up my own vs. wanting to find some existing tool that has some clever math formula.

Both those I linked seem to work fine, though the tapes I'm recovering from are mostly in good condition. The Python one is a bit more robust than the one included with ti99sim, but much much slower and picky about DC offset.

(Note that both of these also decode the TI's frame format; but it should be easy to pull out the core waveform decoder of either.)

rewrite it for speed :)
