Last night i had a live webcast going with 3 other co host from Skype and alot of our viewers was saying that my mic sounded clear but my 3 other co host had a bad echo from each of their mics. how do you get rid of it ?
 
Ok, when you say "they have bad echo" do you mean:

1) They are hearing themselves, delayed, from you when you talk
2) You are hearing yourself, delayed, when they talk
3) The stream contains duplicates of their audio, possibly slightly offset, so that one sounds like a loud echo?

You seem to be using NDI feeds for participants in a Skype conference call, but I wonder if Skype is also sending its audio to your system audio source and that is also being captured?
 
im sorry let me be clear from my end everyone including myself is clear and sounds great. but on youtube my mic is clear but the rest of the guys mics has a echo. i talked to the other guys and they said the same thing everyone is clear and they hear there mics clear also just when we live threw youtube there mics are echo
 
I have the remote viewers to mute their microphones when not speaking,
It helps for them to have headphones on and their mic needs to be close to their mouth.
 
If on the stream there is an echo on all voices but your own, then you are capturing their audio twice somewhere. If you are using Skype to converse, and Skype's NDI feature to capture their voices, then Skype is possibly also sending audio to an audio device that OBS is listening to. Start with a blank scene collection, disable everything in Settings > Audio, and add sources one by one. If you don't get echo, then you previously had an audio device selected that you didn't need, or a duplicate source added.

You may need or want to look at 3rd party software like LoopBack to replace the standard Mac audio configuration panel if you need more control over audio, or you may need to just turn off your default audio output, and use OBS' monitoring feature to hear your Skype participants.
 
I'm having the same issue...an echo on the voice of the guest on skype/NDI. I'm interested to know from @Afig007 if @Narcogen 's last solution solved the problem, or if @Narcogen discovered any other solutions since that October post. I'm in the process of testing that last suggestion and will report back
 
***SOLUTION****
@Narcogen was partially correct in that the audio IS being capture twice to create the echo. The second input is the 'NDI source' in the mixer. What I discovered (...with a whole lot of testing) is that you really only need 'Desktop Audio' open for your Skype audio. Having 'NDI Source' open is redundant and produces the echo. Also part of the confusion may center around the fact that 'NDI Source' doesn't show up in the mixer in the preview screen when you might be more inclined to make this adjustment, only in the live screen.

Either way, just turn down 'NDI Source' and that should solve the problem. It did for me.
 
Actually if you are recording Skype and only want that, use the NDI source and disable the desktop audio.

If you want alerts and want to manage their volume separately from your Skype conversation, have Skype send its audio somewhere else, and use both desktop audio (for alerts) and NDI audio (for Skype).
 
Im having the same issue. Im using skype to live stream with guests on youtube, but everyone in chat says that the guests have an echo. Trevsdad, how do you turn down the NDI audio? I had to turn each guest down in the mixer, but guests say they are too low. I agree, audio is being captured twice, but its a PITA to figure out what and where to turn it down and still have quality sound
 
Not possible to answer without more information. Basically, though, if you have an echo that isn't just being produced by, say, using loudspeakers next to a microphone, the echo isn't caused by something being too loud, it's from audio being directed in a channel that isn't supposed to be there. You can't rectify it by just choosing the perfect volume, you have to find out why the audio is doubled somewhere and eliminate the doubling.

I agree, but I have done everything I know to do. Everyone on panel has also tried using headphones, but the people in chat say that can still hear echo.

I have tried going into tools and changing turning off the NDI output settings off/on (main output and preview output) I have turned desktop auio off, we have tried with headphones only, have tried muting on the skype side just to see if it would pick up from another source, youtube video is muted, etc.


If you was going go live on youtube, using Skype through OBS, what would your settings be? Anyone who does this please help. Its very stressful and ruining my Live streams
 
It's not really useful to say what my settings are unless your setup is the same as mine. I use LoopBack to route my audio upstream of OBS, and I do audioconferencing in Mumble rather than Skype-- my NDI sources are other instances of OBS on my local network, not the Skype app.

Echoes not caused by speakers and mics are caused by duplicate audio streams. Either turn off sources until the echo goes away, or turn off *all* sources and turn them on one at a time until the echo appears to find out which source is causing it.

I think I have to start with this suggestion first.. I have the same issue.. at first we have no problem with our live stream simply because I used window capture instead of adding NDI sources --> in this case, Skype calls. when I decided to include NDI sources (skype conference) in my broadcast because it looks more decent and professional, that is where echoing problems start to bug the streaming. It is our 5th day of broadcast and it's a pity because students are performing live with instruments and vocals only to hear themselves echoing for the duration of the program.


will post update here, in case suggested tweaks solve the problem. TIA.

Como prometí ... Pude eliminar el eco en la llamada de Skype de mis invitados al silenciar el control de volumen de NDI.

Hi, thaks for your answer. I want to know: How can you muting the volume control of NDI? how are the steps?
 
So, muting the volume of the NDI I lose the ability to adjust the volume of individual feeds from Skype. I have the echo even though I do not have any desktop Audio enabled. What's the deal?

Hello. I was able to eliminate the echo by means of muting the individual volumes of the NDI calls.

1. Go to the scene where you have the NDI calls.. in my case, while doing FB live, I have co-hosts. Then look at your mixing console.. the one with individual light indicators.. click the speaker icon of the NDI calls of your guests. This way, duplication of audio will be avoided. That causes the echo: the sound coming from the call itself and another through OBS. Both sound outputs are being broadcasted by OBS. Since skype is your means of communication, you don’t mute that. Instead, mute the audio of NDI in OBS. Worked perfectly for me, I hope for you too.
