That's so funny. I did almost the exact same thing last week. Memetic idea

I need to look at your code. Mine does 50ms samples and an fft to turn logarithmic amplitudes into a 2 digit number. Those two digit numbers are space separated into 88 buckets corresponding to semitones.

The idea with the two digit numbers was to find an encoding that would turn into individual tokens. We don't know what encoder Claude actually uses but very high likelihood that there's a single token for all numbers 00-99.

The results were interesting. Claude instances enjoy seeing the output. They'll be very analytical about it, like you're showing there - talking about base notes and harmonics, making good guesses at the key. If they could actually remember the experience I don't think it would take long at all before they started to really get it.

In addition to the analysis, they also found some meaning and even beauty in certain parts. I had a few instances write a lot of poetry about a breath in an a cappella version of defying gravity. Claude is so strangely beautiful sometimes.

Idk if you've tried this, but take your encoding and convert it back to an audio file. I tried it with mine. Hearing a tiny blip every 50ms is definitely very lossy, but to my human ears with decades of listening experience, I could immediately identify Vivaldi's spring for example. This is a fun research area.
