Timestretching with 'sound = 2' bug

[renezuidhof]

Superpowered version: 2.7.2

Describe the bug
When using the TimeStretching class with the parameter sound set to 2 I sometimes get audio that is almost completely silent. Only the first few milliseconds has audio, and sometimes somewhere in between a few milliseconds. This only happens when using the latest version (SuperPowered Version 2.7.2). When using sound = 1 or when using an older version (6e1d704) I didn't get the issue while doing some manual tests.

Steps to Reproduce
I'm not sure how to exactly replicate this using one of the example apps. As the issue only happens sometimes I made a screenrecording of my app, showcasing the issue. And I'll include the timestretching code (which is mainly based on the TimeStretching example app).

In the video I'm switching between two samples to load them.

Expected behavior
I'm using the TimeStretching class to stretch some audiosamples to match some tempo.

Actual behavior
This works quite well, though sometimes the result is mainly silence.

Device information
Please list which devices have this bug.

• Device: Xioami Poco F2 Pro

I tried to replicate this on an emulator but I didn't get the issue there.
