Couldn't find any.

Description

Vocals waveform didn't stretch/compress when the song tempo/bpm changes midway, making them impossible to use.

Before, audio waveforms being shorter than they should, turning almost useless

After, audio waveforms getting stretched to match the current tempo

This is an awesome fix, and a one-line banger no less!

I just wonder if there's also a way to prevent the slight shifting around of the waveforms with some more changes?

[Hundrec]

I tested this out with Monster and could see the waveforms squash and stretch a bit when there were 2 or more time changes near each other. (scrolling through Section 57)

This is definitely an improvement, but I'd like to know whether there's a more precise formula that could make the waveforms a more similar width across many BPMs?

If not, that's fine! I like this change a lot.

[gamerbross]

i think adding something like that would require a way to render the waveform with different widths, which i have no idea how to, i just messed with the existing things and got this

(really dumb image example)

Thanks for the response!

I'll get this change in since it's a huge improvement anyway :)
