Toggling mute without hitching in UE5.3

[mxbi]

Hi! Thank you for such an awesome plugin.

I want to implement push-to-talk functionality and so want to frequently mute and unmute a recording.
I initially used Start Capture and Stop Capture, but that caused hitching as described in https://github.com/gtreshchev/RuntimeSpeechRecognizer/wiki/6.-Minimizing-freezes#capturable-sound-wave.

Following that, I tried using Toggle Mute to improve performance, but the hitching persists. Looking at the source, it looks like for UE5.3, this is aliased back to Start/Stop Capture:

https://github.com/gtreshchev/RuntimeAudioImporter/blob/main/Source/RuntimeAudioImporter/Private/Sound/CapturableSoundWave.cpp#L172-L184

Is there any recommended way to do this for UE5.3+?

Hi, thanks for the feedback :)

The ToggleMute function used to work in earlier engine versions, but starting from version 5.3, it no longer functions correctly and leads to crashes, especially on Windows (I assume this issue may occur on other platforms as well). To avoid crashes and make sure it always works correctly, I modified it to essentially be implemented as the StartCapture<->EndCapture starting from version 5.3.

For now, I'm not sure if it's possible to solve this in-place, so unfortunately it's on hold for now.
