What is a simple way to bring the vMix audio output (128Kb mp3) from one place to another place over the internet?
The latency must be low (1 or 2 seconds max).
I like to do this with only 2 vMix PC's, without external (paid) services.
I did a lot of searching but I found only local network solutions.

You can use vcall to send a blank feed with audio. Even om non-high latency mode it should stay under 500ms in mist bad situations.

The latency is indeed very low, but the 'host a call' CPU usage is very high (20%) on my i7-4790 Win7 64bit system.
Is there a way to disable video and only send audio?
When I disable video source I can't select an audio source.

Is your audio source the same device as your video source (such as a webcam)?

No, it's an external USB sound card.

Just about an free webrtc service can do this. You'll need some virtual audio cables or Voicemeeter to route the sound at each end. Try https://meet.jit.si using Chrome. Note also that Voicemeeter has its own network capability called VBAN. This passes low latency uncompressed audio over IP. You can use that if you need to receive the audio from afar on a system other than your vMix host.

When I disable video source I can't select an audio source. Hallo, That was my question.Only, unfortunately, nobody could give me an answer. I would also welcome this feature very much. Gruss

I like to do things as simple as possible so I have add a feature request for 'Host a call with audio only'.
I don't know if you already did that (I can't find it anyway).

You've been given at least 3 working solutions to send vMix audio only to remote locations
1 is the use of VLC or FFMPEG
2 is by using ISDN-like services (with a free account) which are in general for radio purposes which is by definition what you want to do if you're not sending video. These work in a browser which can be used directly in vMix through the WebBrowser input.
3 is to use a WebRTC service like Michael Graves suggested. Will work thru the WebBrowser input too if you mind setting this up in an external browser
Options 2 and 3 are very easy to use (Option 1 too if you have a little knowledge to start with)
Some of these will work out of the box when EXTERNAL is on in vMix (use vMixAudio device). Others may require the use of a Virtual Audio Cable or NDI Virtual Input.
I think it's worth "at least" giving it a try...

I watched tutorials of those services on youtube, but it's too devious for me (right now).
I have set up a VLC to VLC connection with port forwarding, that works, but this connection has a delay of 8-10 seconds.
Is there a way to decrease the delay?
You also mentioned FFMPEG, how does that work?

with VLC you can get close to realtime (under 1 sec easily). Tweak your settings If you want to try FFMPEG : https://ffmpeg.org/ffmpeg.htmlI still think it's much easier with the services I suggested or with WebRTC. I gave you all the important keywords to help you build your workflow but I can't do it for you.
