Need to have an option which downloads all waveform at once instead of downloading at playback
It resolve double data useage if already have wavform for that song
Reducing data usage if using mobile data or hotspot
There’s is no waveform extraction on mobile data.
The only use case where batch creating the waveforms should have an advantage that I can think of would be for offline cached songs. Assuming that you are in reach of a charger when you offline cache, creating the waveforms then instead of when you actually use symfonium out in the wild might save a bit of battery. I don’t know if that would be significant tho.
How long are the waveforms taking to come up? Mine usually appear within a few seconds, the exception being when a song has not downloaded into the playback cache. I would imagine that isn’t avoidable, how can it analyze a file that it hasn’t finished downloading yet?
