Thread: Microphone VOX

    Microphone VOX

    Hey all,

    I'm looking to implement basic VOX for the microphone on a Teensy 4.1 with Audio Shield (Rev D). I can see that you can adjust the gain and the level of the input, however, has anyone taken a look at this previously and implemented it already? It feels like I'm probably not the only one that's thought about doing this, however, I can't see anything obvious when searching through the forums.

    Any steers would be greatly appreciated.

    As a starter for 10, I've essentially used the guts of the AudioAnalyzePeak object to check, when transmitting, that the peak of the audio block exceeds a specific threshold. This works, however, it doesn't feel like the neatest solution so I would be interested to understand other approaches.
