  • When using this module, I am seeing a (1.5Vpp) pulse every 13.6ms (73.5Hz). This pulse appears to only occurs if there isn’t enough sound going into the mic. Could this be some kind of oscillation from the op amp? With this periodic pulse, I am having a difficulty determining when there is actual sound coming in or not.
    Also, if I don’t put the mic right next to the sound source, I get almost no (usable) output…

No public wish lists :(
