Administrators Andres Ramos Posted March 5, 2022 Administrators Share Posted March 5, 2022 Today I tried to implement stages from my SkySound receiver in my microphone circuit. Specifically a self adjusting load for the electret condenser microphone and the SSM 2167 noise gating circuit. I got interesting results. Basically the noise from the microphone and environment provides the same pk modulation as with the LED in the SkySound Receiver. But you get the "real" microphone voices on top. Here some examples. Gained with noise gating A sequence gained with noise gating. At the end the last Utterance was repeated and processed: Noise Sequence with NG.mp3 "Wir sind die Toms" : Wir sind die Toms von Sättingen.mp3 "Mach mein"s: Mach meins -NG.mp3 Here voices gained without noise gating: "Andrés, werden uns beteiligen" (poor quality): Andres -NG.mp3 "Am Fenster sitzen wir": Ein Zerrbild wir sind.mp3 "Hab ihn unterbrochen". This voice was gained from a radio football broadcast in the background Hab ihn unterbrochen.mp3 Apart from the fact that the noise gating adds croaky and hissing voices like I know from other devices, the quality of the voices seems not to be different from normal microphone spirit voices. So I think noise gating is a nice idea and implementing it into the microphone offers some interesting use cases with different backgrund sound levels that could be adjusted to slightly touch the noise trigger threshold but basically one could do without the noise gating as well I think. I will do more tests tomorrow. Uns darf keiner mehr jagen.mp3 Er besitzt einen neueren - NG.mp3 1 Quote Link to comment Share on other sites More sharing options...
