> many require high framerate / low latency.

But that's the thing, unless you are _recording_ audio, you can cache and pre-generate the visualisation before hand. FFTs even on 24 192khz 24bit tracks isn't that taxing.

Even visualisations don't have to be that low latency. So long as the audio tracks are in sync you'll mostly be fine.

For waveforms you can literally side scroll the visualisation. You're not going to be pushing more than 60-75hz which gives you 13ms per frame at worst.
