Rendezvous Audio filter and music

We are trying to use Randevous to bring in musicians that have to play during a livestream session.  The only issue is that Rendezvous appear to have some audio filter (probably to reduce echo or noise) but this make the sound be like in a phaser or compressor. Is possible to have the original audio without this filter (for example Zoom have this feature called "Original Audio"). 

Thanks

  • There are no options as far as I know. But lets look at what you are trying to do before we try to fix that anyway.

    I know from personal experience that there is variable delay with different guests via Rendezvous. Lets assume you have a click track going from Wirecast to all guests. Lets assume the guests all just clap at that time. You will get varying delay depending on internet performance for each guest.

    I've actually been thinking about this a lot lately, and Rendezvous certainly does look like an interesting possibility for future musical collaboration. But what would that look like?

    First of all, you would need to setup a video/audio delay of Wirecast inputs going out to live PGM. This delay would be the round trip time for the worst case lag on any connected rendezvous guests.

    Then, we would need a method to calibrate RTT delay to rendezvous guests, with guest audio to ONLY include a click or rhythm track from the main wirecast console. Getting the other tracks with varying delay would be impossible to trying play with. But, if the master click/video from Wirecast was sent to each guest with varying delay based on RTT, that could allow the resulting inputs to be in sync, and when combined with a delay for local inputs would allow live produced musical performance.

    It would be a good one for Telestream to look at, but I dont forecast that one being any time soon. Many more Rendezvous things to look at before getting into live music I think.

  • Greg, thanks for your answer, but jamming over Rendevouz is not my scope at this moment (clearly that will be a killer feature btw because all the jamming program sucks). My scope for now is to have a musician connected with Rendevous that can play his own track and instrument and speak to audience, than move to the other musician and so on, they DO NOT PLAY together: I easily and usually do this with Zoom. The issue is that Rendevous change the volume and compression of the audio source and do not keep constant the volume, trying to adapt noise reduction (I think): this will result in the backing track like being in a phaser and the instrument compress the volume and completely mess the input mix. In Zoom for example you have the option to "use original audio" that will disable all the audio filter that Zoom have (you can in Zoom also disable one by one) and this will allow the audio feed coming from the other side to be heard exactly as the mix is (track, instrument and so on) without any change in volume or compression or noise reduction. I know I can bring Zoom into Wirecast, but since Zoom do not support NDI this open up complexity in the video feed and add extra latency for the audio to be matched with the video from Zoom.

    Regarding your issue, I have not seen it... but I am not using it for musical instruments - only people... so I dont see that - it would need more testing or comment from Telestream.

  • There are no filters applied to Rendezvous short of anything you might add to Wirecast Pro Audio Mixer. Its possible Rendezvous encoding is having an impact on the sound given it may be focused on voice.

  • I am having the exact same issue. I am running a magazine show and trying to bring in musicians live on the show using rendezvous but as soon as they start singing with a backing track there is some phasing going on and it sounds as though the backing track is being cancelled out. Works great for voice but not so good for a live singing and performance which is a shame. Would be the perfect tool to use in this current climate but unfortunately its unusable in this way.

  • CraigS Yes, a huge impact.

    Since it's only impacting music perhaps test with a single musician. That will determine if the phasing is in processing a single source.

  • CraigS yes. I did the test with a single musician

  • Ermanno Bonifazi Perhaps do a recording (our MOV preset) of voice, vs single musician plus a comparison of a recording of the source of both. Then fill out the Support Form and when you get a case number send up the recordings. You may want to compare with a Skype or Zoom recording to exemplify a difference. Keep in mind WebRTC is a different technology and may simply not be best suited for music at this point.

  • Ermanno Bonifazi We believe it's a limitation of the WebRTC codec in use. We'll investigate whether alternate codecs might be viable in such circumstances.

    Given that the guitar itself might be heavily processed you may want to post an example of a clean signal for comparison or an acoustic instrument as well.

  • Will do, will ask my friend to do that acoustic too (but is the same). The same kind of audio signal (and setup on his side), in another conferencing application with "original audio option" (that disable all echo cancellation, noise suppression and so on) work perfectly. Thanks btw for the various response. Support responded bask asking to put in a feature request. Happy Easter.

     It is something we can investigate since there may be variables in how we handle the WebRTC codec(s).

    The reason why I ask for an acoustic source is that it's very easy to process an electric guitar which might sound like the problem exhibited. An acoustic guitar (or similar) may make the problems even more obvious.

  • CraigS Yes we will do the test with acoustic too within this week, but I have no issue with that sound setting in other app like Zoom or Skype.

  • CraigS I did the test again with the beta, and posted my finding in the Beta Thread. The behaviour is the same. One source at the time is ok (acoustic, electric even strumming hard) but not when more than more audio are going on at the same time.

  • I'm not totally sure, but it could be related to the desktop or "browser" version of Rendezvous.  I had 2 different guests.  One used the Wirecast app on their phone to connect and the other used their computer's web browser.  Only the one using their browser had the issue (tried both Safari and Google Chrome).  When they dropped and reconnected using the Wirecast app on their phone the issue cleared up.  I tested it myself using another computer...same issue, but my it works perfectly from the app on my phone.

  • Elvis Bowman The App from the phone is not OK for the kind of setup I need. Is not a "normal" guest invite kind of show. We need musician with their gear to be in. And again this work with other platform that do not compress sound or try to reduce echo. In some way Skype that do not have the "original audio" option like Zoom, have similar (but less) issue than Rendezvous.
