[60fps] Grzegorz Kwiatek (Greg) - "Misunderstanding" -- Chiptune Visualization / Atari SAP

** PLEASE, WATCH IN HIGH QUALITY FOR PROPER AUDIO! **

So, I decided to take a look at all the separate channels of some chiptune music at once. Thought it might look cool, since those waveforms are usually so pretty.

Here's Greg's "Misunderstanding" once more, but in 60 FPS and with the new TimbreCapture algorithm.

This is my favorite Atari POKEY chiptune, but it has a bug: if it loops, the tempo of the loop is reduced to 1/4, which gives this song a very somber and ominous feel to it.

However, that is not how it was intended to be played, apparently, so true to the name that was nothing but a misunderstanding from my part. I still love that bugged version and to me that'll always be the real version of this song. This video with 7:03 minutes displays the slowdown bug in the second part.

This is a video made with a complete rewrite of my original Python script. I finally got around to implementing my "TimbreCapture" algorithm, which finds the exact waveform shape being repeated for a note (the timbre's minimum waveform) and consistently centers it on screen. This way we can always see the exact shape of the wave being played at any given moment and how it changes.

It's working well so far (misses a few weirder waveforms), but I still need to add a couple more features to it.

Oh, and there's more! I'm also going to be releasing my tool to convert POKEY dumps to MIDI files. These will require a modified version of asapscan from the ASAP library.
