Clipping/Popping sound during playback on device #2

Open Voqera opened 3 months ago

When testing on a device (iPhone 14 Pro) I'm getting audible clipping or popping sounds. This makes the playback a poor experience.

This doesn't appear to be an issue when playing back on the simulator.

I've tried passing a reduced volume into the player and using a proxy API for OpenAI, adjusting those variables doesn't impact the issue when played back on the device.

Anecdotally, the overall volume does seem to be louder than I would expect for the device volume and the player volume levels

Appears to be localized to the .aac format. Using .mp3 does not have this issue.
