Lower the mic sound quality OR simulate the noisy intercom sound

[KrustyFM 1]

Hi everybody,

in lack of a "soundcard" forum, I try to explain my request here . Please feel free to correct me.

Since I plan to build my own simpit one thing bothers me: The too good sound quality using a microphone for e.g. "intercom" (two hedsets). Voices from the radio using e.g. pilots edge sound like the guy sits right next to you, it's a to clear sound .

Out of the box and using the standard Windows settings real life radio and intercom just not sounds like the real thing. Windows 10 even can just raise the quality for its mic input but lowering it is not provided. I recall that Win95 had an option to set the sound quality to "telephone" which would be great here now.

Does anyone know a little trick (software, settings etc.) to lower the sound quality just for the microphone and imcoming radio chatter?

Appreciate any help :).

Kind regards.
