  • Question regarding the Gate output on the sound detector breakout board.

    How short of a duration sound event (of adequate amplitude) will trigger the Gate output to go HIGH?

    Then, how long will the Gate output remain HIGH after the sound event is over?

    I’m trying to detect each tone in something like a fast-busy signal you might experience in telephony. So would a tone sequence that is say a repeating pattern of 100ms of sound followed by 100ms of silence followed by 100ms of sound … show up as essentially a 50% duty cycle square wave on the Gate output? Or does the Gate output remain HIGH for a duration after the sound has stopped that would prevent rapidly repeating tones with an On/Off pattern from being detected as individual sound events?

No public wish lists :(
