First off I wanted to express my appreciation for the simplicity of this call in option. I switched from OBS entirely for this feature. I understand there are limitations on call audio quality and it will probably never be perfect. I'm ok with that because of the interactive capabilities between callers and pure ease of this vmix call. I've used desktop cap for skype and facebook but the caller interaction and ease just weren't there and it gave arise to a host of new audio issues like virtual cables and such.

In vmixcall whenever I have someone sing live music the mics seem to auto adjust. It drastically decreases the quality of the call. When the beta vmixcall first came out there was an option when caller logged in that was able to turn off mic auto gain and echo cancellation. When we ran a test at that time the audio improved quite a bit. Still not perfect but it was getting tolerable. Now a couple days after the test when we went live the option to select was no longer available in the beta. Sound audio quality is decreasing again just when the music starts getting good.

My question is this, is there settings to shut off auto gain and the echo cancellation again on my end or the callers?

What settings should I be using to get the best audio for live musicians on both our ends? Some guests just use phone, some have audio I/O and the irig. Even the guests using a decent audio I/O seem to suffer from this issue on live stream.

One last issue is all of a sudden the singing speeds up. The callers feed just increases, i am not even able to tell it was slow or anything it just speeds up out of nowhere. Is that a buffer setting or something?

Thanks for any help in advance

Use beta.vmixcall.com, you can uncheck echo cancellation and check stereo. That should vastly improve quality.

I did miss a line it seems :-)

The echo cancellation option is still there, you might have to use another browser: https://imgur.com/a/Dp1LFfD

How are you evaluating quality? Locally from one computer to another?


I don't use it for music in particular but have used it with video playback. Webrtc is ultimately designed for voice but given high-end hardware on both sides, echo cancellation turned off and a good peer to peer connection, the quality is very good.

In the end, if you want really reliable, good quality music on a live stream, you'll have to pre-record and playback.
