Not possible to disable noise reduction

[andriiK]

The microphone is constantly in use. I understand that it is included for noise cancellation. In the settings, I turn off the noise reduction, but it has no effect.

Because the noise reduction is always on, the music that is in the video that is being shown is muted and I can't hear the sound of the video, only the words. It can be disabled only by denying access to the microphone for the "ZOOM" application. But then I can't talk to the participants. Therefore, I have to deny access for the microphone to hear the videos being shown, and when I want to say something, I allow access and it is very inconvenient.

hi andriik,

this may explain what is happening.

The issue with music and singing being suppressed is due to background noise suppression.

According Office Hours Worldwide panelist, mickey macachor:

Zoom's primary use case is for meetings which is primarily human speech. Thus, the noise suppression facilities built into Zoom is designed to consider music as noise. There is a feature in Zoom called "Original Sound" that allows one to defeat the noise suppression though.

According to support article:

“Note: If you enable Original Sound for Musician in a meeting, all noise suppression is disabled. If you disable Original Sound for Musicians, the client reverts to the noise suppression setting that you chose in client settings, meaning it could be Auto / Low / Med / High.

Using original sound for musicians in a meeting – Zoom Support

The problem is that the noise suppression setting is not being disabled by selecting original sound for musicians. 

The workaround is configure your zoom client:

1. first set background noise suppression to low for Zoom optimized audio.
2. second select original sound for musicians.

original sound for musicians options are:

• High-fidelity music mode: This disables echo cancellation & post-processing, while raising audio codec quality to 48Khz, 96Kbps mono/192kbps stereo. Professional audio interface, microphone, and headphones required.
• Echo cancellation: Prevents the creation of echoes between mic and speakers. Disable only recommended when using headphones to isolate audio or when playing instruments.
• Stereo audio: Encodes mic audio in stereo. Requires a stereo-capable microphone or audio interface.
