Add option to wait for audio (Sampler)

[NuclearMeltdown]

Hi, I'd like to suggest an option for the sampler to wait for an actual audio signal to start recording. If you're expecting someone to say something, it can be quite difficult to time the start of the recording properly. Clip audio would fix not being able to press quickly enough, but it's a fixed length, so not ideal. An option for the sampler to listen to the audio signal while holding down the button and automatically starting to record once it detects a certain level of audio would be nice, if possible.

Thanks!

Hey @NuclearMeltdown 👋 I experimented with this a few years back in the form of a GatedAudioRecord; audio would only start recording when it was actually received, i.e. the first silence was ignored. I could certainly look into adding this back in as an "experimental" feature.

This would be absolutely phenomenal if you wouldn't mind making it a feature!
