Audio very much messed up on final recording.

So I have purchased Wirecast Pro 14.1.1 three weeks ago and love it.  Some issues back and forth but most I can work around.  So far I have not been able to fix that randomly the sound has a bit of rebotic effect on it. I was lucky once that my guest on rendezvous noticed it and I rebooted the entire system and it was gone.  I have an i7 with 32 gigs of ram on a water cooled system.  But today I did a show with no guests. So I was not able to tell how that audio was sounding.  I have to monitor the board sound because monitor the final sound is always a few seconds behind and sometimes creates double sound.  But this time with no guest I did not notice the issue till the hour show was completed and the host was gone.  Lucky for me, I have backups after backups of all the work I do. So I also recorded the audio on Cubase which is what I use for the timing of the show and commercials.  (I have yet to learn how to do a timed show on wirecast. But I just have not found the right youtube training videos yet)  So because I have a backup of the raw audio from the board I was able to use lightworks to import the saved video from wirecast and then overlay the sound from the board recorded on Cubase and finally nudge it to match the lips of the host.  He has no idea that I failed horribly on producing his show, which is good for me. But I would like to know why it happened and how to ensure it does not continue to happen. 
SAMPLE OF THE ISSUE

https://www.dropbox.com/s/rcguctjrpcnpc6j/MyStream_43.mp4?dl=0 This is the full show as it got it from my storage folder after the show was done.

https://www.dropbox.com/s/pstpfugq01hy52d/Ep%2070%20Church%20Hurt.mp4?dl=0 This was the full show after I used the backup file from cubase that was recorded on the same computer so it is not the audio board, or the USB connection.

Any ideas would be helpful.  Oh and the CPU usage never went over 40% during this show.

     It depends on what the sound source was, what the sample rate was of the source, whether you were hearing it in local monitoring, the live stream, the recording.
     

    It's not clear what Cubase role is in this but that adds further complication because the DAW may be part of the problem.

     Sorry but I not completely understand the intent. Audio from the board will let you know how input is (assuming that's what you're monitoring). Monitoring Wirecast is the ONLY way to know how it's processing the sound. It will be delayed because... it's processing the sound. Monitoring the stream is yet another place that tells you how the encoder/internet/server/CDN is handling Wirecast output. Generally, the most critical point is monitoring Wirecast and using mix minus if the delay bothers the host.

    • CraigS  well the presonus board has a monitor out that can be selective to the sources.  I pipe in the rendesvous sound to a second sound card so I can that to the 11/12 source on the board so it can be monitored real time but not added to the mix.  Since wirecast pull that audio automatically and the background music is coming from Cubase with the timers and that runs through 15/16 on the board and is added to the mix.  So the mix is the mics in the studio, the 15/16 from cubase and that is mixed to one channel on wirecast in the bottom row.  Then each of the rendevous sources comes in and I have a merged shot with all of them so they can interrupt each other and separate shots with the host and each guest to force mute anyone that is not desired to talk.  (rendevous does not offer shortcut keys for muting guests that I could find.)  I have done a number of shows without any issue and after a reboot it all works fine.  But when people are discussing stuff monitoring 2 to 8 seconds behind does not work.  So I monitor the direct sound from the board which is then split 8ways and sent to different headphones for staff in the building to monitor.  We are not streaming it yet. because I read that if you just record you get a better quality than if you stream AND record.  I can always stream later or with OBS after we have a clean recording.

      As far as for the sound source, to be honest I am no expert.  The board says 24bit 196khz on it.  I just watch alot of youtube videos and learn as I go.  I was told wirecast can take sound straight from the presonus board which is why we selected it and that it was a one time cost.  (nice option than the pay monthly services that change all the time what they do)  So I just select the Presonus MAIN L/R has the sound source.  Does that help at all.  how would I found what sample rate is?

      Joseph Boy The complexity of your setups allows for many potential problems.

       Which may indicate a setting is changing and reboot sets it back to a default.

      You're going to have to strip everything down and test each element independently using a new blank document for each test.

      • With a New Blank Document.
      • First test with a single audio source from the board into Wirecast. This confirms the feed into Wirecast is good.
      • Monitor Wirecast directly from the Wirecast computer through headphones. This confirms Wirecast processing is good (no sample rate or similar issues).
      • Test by doing a local MOV recording to disk. This confirms encoder output is good.

     That should have no impact if your setting are good and your CPU is under 60%
