[…]
[4:16 PM] Josh: I’ve been using one cc thread all day and having it spawn others to do things in this general area
[4:16 PM] Josh: originally was having it do sega genesis and snes soundchip emulation as seen [here](https://youtu.be/ANYxysB0HtA) (edited)
[4:17 PM] Josh: and then saw a tweet suggesting the use of supercollider https://supercollider.github.io/

  so asked the main opus to fork and have another pick a different song to cover with it, leading to [this one](https://youtu.be/XlAZThRt-jw) (my fav) (edited)
[…]
[4:22 PM] Josh: asked for three more supercollider covers and looking forward to see if similar or better quality

[5:55 PM] Unnamed: Also did you mean earlier that you were working on a music ai tool?
[…]
  > and also this UI last week (or week before actually I think) for me to give feedback
[6:07 PM] Josh: this (https://audio.fjpaz.net) is basically designed for working w/ AI
[6:08 PM] Josh: the idea is that it’s like gdocs’s comment system

  but for track segments in a WIP
[6:09 PM] Josh: I wanted it to work for human <> human,

  and/or human <> AI, 

  and/or human <> AI <> human
[…]
[6:16 PM] Josh: the reason specifically that I prompted for this to be made was that

  I had given claude (Opus 5.5) some MIDIs and wanted to see how well it could prepare some instrumentation, FX etc

  to see how nice its renditions might sound
[6:16 PM] Josh: and I was quite impressed overall but some tracks had some problems (since it can’t hear; it can only use waveforms and other data to look at / intuit what the vibe would be)

  so I wanted to try marking up the audio directly

  basically similar flow to vibecoding a webapp.. just pointing out the issues for it to look at, take into account and try fixing

### [layers-of-sound](https://fjpaz.net/annotate#layers-of-sound) · text excerpt

I’d like it to annotate not only the layers of time but also the layers of sound. … We can take a couple of cues from SoundCloud. SoundCloud isn’t precise, and it isn’t deep …

And yet something about its simplicity is really clean. Maybe … this can be its own studio for listening <> annotation
