Great to have Original Audio as an option , but echo Cancellation would be super helpful for using this in Hybrid scenarios

As per https://www.vmix.com/hel...ZoomMeetingSettings.html it says (see last line): Quote:This adjusts the audio sent from vMix to the Zoom Meetings as follows:
Reduces noise suppression
Enables stereo
Increases audio quality (via higher bitrate)
Disables echo cancellation
Note though that if you have multiple Zoom Inputs you can have different choices set for this option. That is, enable it in one Zoom Input and disable it in another Zoom Input, thus not knowing if it is enabled or not.

I would love to see it implemented.
I want the ZOOM participants in worship to hear praise in original sound, but echo cancellation needs to be “on” when the ZOOM participants pray.

In order to use vMix as a Zoom source in hybrid conferences where the sound goes to the PA, we need to be able to play the original sound, but leave the echo cancellation on. Without this, there is no way to use vMix.

Without this, there is no way to use vMix. This is very true. Please take care of it. It will greatly improve the usability of vMix in many scenarios.

Ideally, I would like to be able to switch echo cancellation ON/OFF while the original audio is turned ON.
If that is difficult, I would like to be able to control the original audio ON/OFF from the API.

Hello vMix Team, I'm writing to request an enhancement for the Zoom integration feature in vMix. After reviewing the vMix 29 help documentation, it appears the "Original Sound for Musicians" setting still operates the same way: https://www.vmix.com/help29/ZoomMeetingSettings.htmlSpecifically, it seems we cannot enable "Original Sound" and "Echo Cancellation (EC)" at the same time.My Feature Request:Could you please add an option to toggle Echo Cancellation ON or OFF while Original Sound is enabled? This functionality (EC ON + Original Sound ON) is available in the standard Zoom desktop client. Why this is critical (Use Case): This feature is essential for scenarios like hybrid online church services. We need to send high-quality audio (like live music) from the venue using "Original Sound." At the same time, we need to play remote participants' audio (for prayers or scripture readings) back into the venue's speakers for the local congregation to hear. Without EC enabled, this immediately creates severe echo for the remote participants, making hybrid interaction impossible. I am wondering if this is a limitation of the Zoom SDK. However, based on the Zoom Developer Forum, it seems controlling AEC might be possible. This thread suggests that AEC can be managed via API calls like or Code:stream.enableBackgroundNoiseSuppression()
: https://devforum.zoom.us/t/support-for-echo-cancellation/108253It would be fantastic if the vMix team could investigate combining these API controls with Code:stream.enableOriginalSound()
to implement this requested feature. Thank you for your consideration!
