early tests of analog recordings compared to digital ones revealed that music played back on a CD format had much less of a positive impact on depressed patients than the same recording played back on a record.

The bodies in that room would, presumably, also experience that difference-even if we humans can't immediately put a name or metric on exactly what that difference is. MAKE SURE TO CLARIFY HOW MIDI CONTROLLERS WORK [Discrete cosine transform - Wikipedia](https://en.wikipedia.org/wiki/Discrete_cosine_transform) - already on TT Files NOTE: bring up electrostatic speakers NOTE: bring up microphone types: ribbon, etc. bring up MIDI and how it corresponds to music production bring up audio trackers and how they're basically drag/drop interface along a chronological sequencing - i.e., each sound effect/loop is essentially atomized, then put together to make the song MUSIC HAS A PSYCHOLOGICAL EFFECT technically, ALL the music that will ever be popular has been made - the only difference is that they permute some things to make it "new": - change the tempo, usually faster - change out instruments - play multiple harmonies together ## 0commentary [Underwater ears everywhere | Hacker News](https://news.ycombinator.com/item?id=36750716) [2023-07-15 underwater ears everywhere](https://computer.rip/2023-07-15-underwater-ears-everywhere.html) [Audio Sparklines | Hacker News](https://news.ycombinator.com/item?id=30027405) [Audio Sparklines · Melatonin](https://melatonin.dev/blog/audio-sparklines/) ## audio codecs and protocols [Lyra audio codec enables high-quality voice calls at 3 kbps bitrate | Hacker News](https://news.ycombinator.com/item?id=26300229) [Lyra audio codec enables high-quality voice calls at 3 kbps bitrate -
