Flickering on microphone effets

[BaptisteHudyma]

The sound reactive animations are fickering noticibly.

This is because:

• the mic data is set on interrupts
• the animations are running on another thread
• The mic data is cleared on read

All those parameters interacting together produces the flickering effects in my opinion.

Potential fixes:

• Do not clear the data after reading (potential for data smearing)
• Keep the last value after computation on valid data and return it instead (again, potential data smearing)
