That's necessarily going to be aspirational in at least some respects, though—it's limited by the hardware.

- spicybright 5y agoI wonder if there's a way for computers to self-measure round trip. Even if you have to plug an aux cord between the speaker + mic jacks.
- moonchild 5y agoPeople have done experiments using high-speed cameras and such.
- mjn 5y agoMy first paper as an undergrad measured MIDI round-trip by tapping the input and output MIDI wires and then looking at how the signals were offset: https://www.kmjn.org/publications/MIDI_ICMC04-abstract.html https://www.kmjn.org/publications/MIDI_ICMC04-abstract.html For keyboard input, one paper (whose citation I can't seem to find) used a clicky mechanical keyboard, pointed a mic at the computer, and measured the offset between each corresponding pair of keyboard click and sound output.
