- amelius 6y agoYou could ramp up/down the voltage gradually. Anyway the thing is connected to an ADC. The computer can sense when the switch is turned on/off, and turn off (or flush) the audio pipeline at the appropriate times.
- formerly_proven 6y agoHow does the ADC distinguish the transient from switching the bias voltage from an intentional signal? (Yes, if you see the entire waveform, this is quite easy, but because of the low frequency, this would incur another ~20-50 ms in latency, which is unacceptable). Ramping the bias voltage requires additional components (cheapest way these days would probably be a separate DAC integrated into the audio codec, but then you are back to not having a physical kill switch) and also incurs extra delay for turning off and on (probably 100-200 ms).
