@Garzas looks like you are rolling back kalium to a previous commitish.

This means that the PR's target branch (develop) is using a newer version of Kalium, and the changes in this PR will rollback Kalium to an older version.

Wav will be bigger in size than m4a, maybe it's not as big as to become a problem, but maybe we could think of compressing it not when recording or right after, but when sending - it won't be as problematic to the user as now. Also, maybe applying effect takes longer for wav than for m4a because of bigger file size, but I have no idea, just would be good to verify it. 😄
Anyway, well done!

Amazing work done here 👏🏻

Generation of the file with effects is now super fast as compared to before 🏃🏻‍♂️

Tested on Android + iOS + Mac wrapper and everything is as it should be, awesome!

The previous issue with m4a file was due to having to decode from m4a to wav and then from wav to m4a back again thus leaving us with a bit of delay when generating the file with effects, my personal opinion is that wav will still be faster than what/how we were doing before, but it would be good if we could run performance checks on both types 👌🏻
