Random audio stutter on audio track 1 - same audio on another track is fine.

Hi,

This is a long shot but I'll ask anyway.

I record DJ sets in OBS from my Pioneer DJ gear. I keep getting random stutters in the mix. They last like a half a beat and they're not very frequent, but in a mix there can be 2 or 3 of them depending on the length of the mix. For the amount of effort I put in, and the amount of money i've spent trying to perfect my audio set up, and just that i'm a perfectionist, i really hate these blips in my videos (I put them on YT).

I run RCA cables out the back of the mixer into the line in port on a GoXLR mini. I used to stream (games and DJ sets) a lot and always split my audio in to separate tracks in OBS. GoXLR gives you 5-6 audio devices to send audio to, so I break it out that way.

I had been capturing the "line-in" audio by simply adding an ASIO input in OBS and capturing the line-in ports, and send it to tracks 1 and 4. 1 for stream and 4 for capturing clean audio if i wanted to use the VOD. Track 4 seems to capture the audio fine, but track 1 had the blips. I thought it was because I was using the ASIO driver to grab the audio.

So instead, in the GoXLR software I tried just sending the "line-in" input audio to the "broadcast stream mix" audio device. I then captured the ASIO line-in on track 4 as before, but just captured "broadcast stream mix" on track 1.

Both ways I get the blips on track 1, but not one track 4, so that seems to rule out ASIO being the cause.

The audio stream is definitely reaching the computer perfectly because on track 4 it's fine. I recorded the same mix in the DJ software to a wav file and that is fine too.

I noticed the "use device timestamps" wasn't checked for the "broadcast stream mix" audio input in OBS. I enabled it and tried again but there were blips still.

My next plan is try record the same device in Audacity at the same time as in OBS to compare. That would at least rule out it being an OBS thing or it might point fingers at the GoXLR doing something wonky.

Does anyone else have any ideas of what I can check?

Thanks.

Hello. Just bumping this.

I have confirmed now that the problem is OBS. I recorded the same "Broadcast Stream Mix" audio device inside of Audacity at the same time as recording in OBS, and there are no blips, so something is happening in OBS to add the blip to audio track 1. Very strange.

The blips are so tiny that I bet anyone who does listen to the mixes I'm recording won't actually notice them, but the perfectionist in me really needs to figure it out.

Thanks

Allo,

Bumping this again.

I recently recorded a mix on a different computer using my other computer which also has a GoXLR connected. Same thing happens on that. Defo an OBS thing.

I tried disabling all the "use device timestamps" I could. I have an ASIO device for the GoXLR Line In using the OBS ASIO plugin that I don't have that option for so I will try a recording with the ASIO plugin removed.

Just to also confirm that recording the same audio device that OBS records ("broadcast stream mix") in Audacity results in a flawless recording. The audio is getting into the computer perfectly, OBS is doing something. Maybe something to keep the audio from going out of sync?
