Audio Processing - Zoom Room

Dear Zoom Community,

Good day! We would like to ask for a consultation regarding our Zoom Room setup.

For context, we are trying to eliminate or at least minimize cross-talking (a ducking effect) when far-end and local audio are talking simultaneously.

The actual scenario is that the local audio is being suppressed when the far-end and local will talk at the same time (being observed with a third party who is listening for both local and far-end speakers). This audio experience is present when using two distinct DSPs; we remove the audio processing in the microphone and DSP (AEC, AGC EQ, etc.), along with the removal of poly’s “noiseblock ai” to isolate which device is processing the ducking/suppression and we felt like there is processing happening in Zoom Room even though we disable (‘off’) noise suppression.

In the article I read, there is a note there saying “there is a basic noise suppression feature in the background that cannot be disabled.” Is there a way we can set this setting off, and how?

We have two separate systems having different DSPs:

Microphones: Shure MXA920

DSP: Biamp TesiraForte Dan and QSC Core

MTR Codec: Poly G7500 in Zoom Room Environment

Zoom Room Version : 6.4.1

Thanks,
Kinjojo
