Q: What is denormalization?
A: In short, when the sound doesn’t play, the plugin starts to use several times more CPU power. It’s related with processing of very small numbers very very close to zero (less than -600 dBFS).
Q: Molot 0.3 didn’t have such problems, so why they were added to version 0.3.1?
A: This bug is related with combination of new limiter code and auto-off feature.
Q: What is auto-off feature?
A: When there’s no input signal, the signal processing code is bypassed. If it happens, version string on GUI becomes gray.
