Producer/Host audio in Rendezvous

When I'm hosting and producing my own show my guests are complaining that I sound like a chipmunk. They are connected via Rendezvous. I'm currently running the latest version of Wirecast 14.1

 

Is there a workaround Craig?

 

Thanks

Dave

  • Sounds like a sample rate issue but that's just speculative.
    Perhaps it's related to the audio device you're using and its sample rate being speculative as well.
    Try changing the audio source/mic you're using and see if the audio source/mic is related.
    Try calling in from another computer you have access to and hear what it sounds like. If you have another person with you, they could talk.

    Perhaps test in 14.0.4 using all the same equipment to see if it's specific to 14.1 beta.

    All posts about the beta should be in the beta forum so I moved the post.

    For this issue, we'd need complete details so we can attempt to reproduce.

  • Thanks, CraigS  - this issue is only on the Rendezvous platform and not on the main audio output. No issue with the audio device or settings because I use it for all of my calls across multiple platforms. Is there a location within Rendezvous to change the audio sample rate? Also, I've been having the same issue with 14.0.4 so it's not limited to 14.1 Beta

    Thanks

     Settings used in other software may not be relevant to Rendezvous.

    Dave Hatch said:

     No. Since others use this as well it's why we have to look at the device specifically. 

    If you set up the device in a Wirecast shot you may be able to change the settings there and Rendezvous may see it.

    CraigS said:

     Again please do this test if you can. It would provide more first-hand information than relying on guests which leave open variables we can't account for.

  • I had this problem on a live last week. We tried to connect a remote guest via Rendezvous and it work for a while then our output to the remote guest made the presenter turn chipmunk. The audio feed from the guest was fine. If we reset the remote connection this problem fixed itself, then randomly it came back. I tested on a local machine and the chipmunk voice returned. 

    We ended up using Skype and NDI into Wirecast. 

    We did buy the pro version to use rendezvous for remote contributors. 

    I am a bit disappointed as Rendezvous has not worked in previous versions and I hoped that this had been sorted in 14 like most of the reviews said.

    Any help or a resolve would be appreciated.

      james braybrooke Was this in 14.0.4 or the 14.1 beta.

       Please explain exactly what you did to reset the remote connection as it might help us find the cause.

  • Hi Craig, 

    we had to restart the browser then reconnect to the session, it was safari I believe, I also tried in locally on chrome with the same error. Just disconnecting and re-connecting didn't work in solving the 'chipmunk' problem. 

    We was using the latest stable on a window 10 machine, 14.0.4. The computer is a 8 core windows 10 pro machine with 32gb of memory if that's any help. The remote machine was a MacBook Pro and a HP laptop windows 10.

     You mentioned sounding like a chipmunk. What "error" were you seeing. 

    What was your audio source and did you confirm the sample rate?
    Ideally, you should put the source in a shot and then check the Device Properties. 

    If it's not happening every time but it's fixable then we need to find out what changes before and after.

    Please describe as if you wanted someone to do everything the same including the equipment.

     For example. If it's the device that disconnecting and re-connecting won't have an effect.

     Sorry, but the guest would be using the browser. 

    Please explain from the start, step by step. I can't many any assumptions when troubleshooting.

  • 1. set up rendezvous session 

    2. send link to contributor

    3. add contributor into workflow (we had audio from going to ear piece and audio from mixer to microphone (mix minus clean feed)

    Audio from contributor into Wirecast was working fine we had no issue with the incoming audio

    Audio from Wirecast to contributor was sped up and high pitched (sample rate is a good shout but there was no way to check on contributor end). No error messages where displayed.

    'chipmunk' mode was sporadic and could be fixed by contributor restarting their browser and reconnecting, we also got it to happen on one of our local machines when connecting via Rendezvous so ruled out it being a fault on the contributors machine. 

    Does that help?

     I was referencing the Rendezvous dashboard, disconnecting the user and reconnecting to the previous session.

     was using a mixer with USB audio out which connected straight into the Wirecast Computer. This was the only sound source we where sending.

     Making sure there was no third party driver involved. Just standard  USB recognized by the computer using the built-in driver.

      The technicians testing would like to know the specific audio mixer you're using and any sample rate, bit rate, etc. settings. They want to exactly match the settings from the mixer into Rendezvous.

  • CraigS - have the technicians call me and I'd be happy to walk them thru it. LOL

    I was successfully able to recreate my issue with 2 machines here in my home office. I'll do my best to type it out in a cohesive message. But first here are the specs

    Wirecast Machine

    • ThinkPad P53
    • i7 9850H @2.60GHz
    • 32GB Ram
    •  Windows 10 Enterprise
    • Wirecast 14.0.1 and the updated to 14.0.4 (with no changes to the issue)
    • Logitec USB Headset

    Guest Machine

    • ThinkPad T480
    • i7 8650U @1.90GHz
    • 8GB Ram
    • Windows 10 Enterprise
    • Chrome 87.0.4280.141 
    • Firefox 84.0.2
    • Wired Sony earbuds with onboard mic

    Network

    • Both machines are hardwired 1GB network
    • Internet Connections speeds 50Mbps/10Mbps 

     

    I am not using any outboard or special equipment everything is done within the Wirecast/Rendezvous environment

     

    Here are the steps 

    • Start Wirecast and start a new Rendezvous session
    • Send link to other machine and make a successful connection via Chrome and Firefox
    • In the Rendezvous Mixer turn on USB headset to speak with  the guest (the guest hears a very gated and process sounding audio)
    • Turn on and off the USB headset in the Rendezvous mixer to try and clean up the audio. It kind of works.
    • After turning the mic on and off 3 times the audio gets very bad from the Wirecast machine USB mic to the Guest.
    • After another 2 times of turning on and off, the USB  tries and it cleans up to something that is understandable
    • Click the checkbox in Rendezvous Audio to send the output of the document to the guest (so they can hear video playback)
    • After playing back a short 10-second video the guest can hear the audio of the video but when the Wirecast USB headset is turned on again to speak to the guest the audio is inaudible. It sounds like there is some serious audio processing happening, doubling the voice (like a multi-tap guitar effect) and also gating it.

     

    To me, it doesn't sound like a sample rate issue because it's not consistent every time. This happens every 3rd or 4th time after I turn on the USB headset.

    There are no error messages reported nor does Wirecast or Rendezvous crash.  There is not red P located on either machine indicating that it's being routed thru the Wirecast servers via WebRTC

     

    Also to note that the audio from the Guest is clean in Rendezvous and on the Wirecast recordings. It seems this issue is isolated to the rendezvous platform

     

    Thanks

     But you are using a USB headset. Any external audio input or output might be part of the issue.

    I wonder if you can reproduce the issue with a wired headset (computer audio output jack rather than USB) on the Wirecast machine?

    A USB headset is standard equipment these days.

    That can certainly cause an issue. That was the case when I was an Avid engineer at a major broadcast facility. Certain USB Keyboard and Mouse combination caused Mac based Avid's to crash. We found there was some variation in the USB spec used by some keyboards.

    It's not about whether what should or shouldn't happen. It's about understanding the cause so we can fix. In order to confirm the USB headset may be at issue, the "control" would be to test using headphone jack or equivalent to monitor.

     And the bus management USB audio in and out at the same time can be an issue and we need to explore that.

  • CraigS  - thanks for the follow up that makes more sense to me. I'll see if I can find a headset that can connect via headphone jack as the control to see if it eliminates the issues.

     I agree with you to an extent, it is important to understand the cause in order to fix the issue. But I've paid for this software/support and feel like this issue shouldn't be tested by the public. It could have been caught in the QC process of your dev team and flagged. USB keyboards, mice and headsets are all standard equipment for most people these days. All of these devices should be stress-tested in various combinations by your dev teams.

    As was the case with the Avid Mac keyboards sometimes the issue is specific to one make or brand or specific model series or one variant.
