just had a 3AM fucking brain blast

On the TI-8x line of calculators, you can do link port shit to essentially blit music to the barrel link port. However, the only library for this sounds like dick and is a superslow piece of shit.

I've just had a thought:
The library this dude wrote spaces the note out, waits for it to end and then resets the port.

If you're blitting music to the port rapid-fire, you don't need to reset it except either after the music or during rests. I can push a note with a waveform of 0hz to the link port to reset it, so...

The dude posted his source, so I could theoretically have it set the link port to whatever note and immediately return.

This would make the time between notes upwards of like 8x faster, bringing my sample rate from like 25 to 200 or so. That's almost fast enough for barely-recognizable voice synth! A little fiddling would be needed to get me the rest of the way there, but there's probably optimizations I can do to push the envelope some.

We can hide messages in images via steganography (or ZIP sewing), we can hide messages in sound via either sound-based transmission (like Morse) or waveform-based transmission (think oscilloscope art videos), we can transmit it in videos in like 300 different fucking combined forms...

Encryption isn't the ONLY way, yo. Social engineering and being a cheeky shithead can get it done too.
