Question / Help Audio Lag

[ozzbourne]

http://www.twitch.tv/ozzbournetv/b/469383591
This first link is me using Xsplit and the audio is clear and not choppy at all.

This second link is me trying to use OBS, the audio comes late and then speeds up. I have tried a bunch of different settings and nothing seems to be working. I really dont like Xsplit because it is a slow program and dysfunctional most of the time but I am about to just suck it up because OBS isn't working properly. Please help! :(

Bump

 

[dodgepong]

I see you're using the "Force desktop audio to use video timestamps as a base for audio time" setting...does the problem persist if you turn that off?

 

[ozzbourne]

Yes it does :( I have tried everything.

 

[Lain]

If the audio timing is off, first try "Use mic QPC timestamps" in advanced with 700 scene buffering time. If that fails to work, turn that off and use "Mic sync fix hack". One of those usually does the trick in these cases. In the future hopefully this will be fully automatic/fixed and the options won't be necessary

 

[ozzbourne]

Sure will give it a try and let you know c:

 

[ozzbourne]

Neither of those settings fixed it :(

 

[ozzbourne]

About to just say screw it and delete OBS. This is the most frusturating thing.

18:38:23: CFR: no

Turn constant frame rate on and post a new log file that consists of both at least two minutes of streaming and from when you encounter the problem.

18:38:23: Audio Format: 48000hz

18:38:23: MMDeviceAudioSource: Frequency for device 'Speakers (High Definition Audio Device)' is 352800, samples per sec is 44100
18:38:23: MMDeviceAudioSource: Frequency for device 'Microphone (High Definition Audio Device)' is 352800, samples per sec is 44100

Just a shot in the dark, but try running OBS at 44100Hz instead of 48000Hz, since your audio inputs are both running at 44100Hz.

 

[smite]

I'm having this issue too, stereo-mix audio is over 3 seconds delayed behind the video and it is something that suddenly appeared in the last month or so. OBS has been working fine for me for a long time until recently. I haven't changed my settings until I tried to fix this problem, but nothing seems to affect it. It even occurs when recording local video.

Turn constant frame rate on and post a new log file that consists of both at least two minutes of streaming and from when you encounter the problem.

18:38:23: Audio Format: 48000hz

18:38:23: MMDeviceAudioSource: Frequency for device 'Speakers (High Definition Audio Device)' is 352800, samples per sec is 44100
18:38:23: MMDeviceAudioSource: Frequency for device 'Microphone (High Definition Audio Device)' is 352800, samples per sec is 44100

Just a shot in the dark, but try running OBS at 44100Hz instead of 48000Hz, since your audio inputs are both running at 44100Hz.

I had this problem a little while ago and found that this was the problem. As soon as I matched up my audio outputs and the OBS output at either 44100 or 48000 the problem was solved. I recommend trying what this person suggested.

Xsplit license expires in 2 days, hopefully we can fix this pretty quick.

I tried every setting under the sun and none of them worked. But I did a restart and reinstalled my sound drivers and managed to have a normal stream afterwards with no audio delay. I'll post again with an update as to whether the problem remains resolved.

If your mic is after the video, first, turn up your scene buffering time to like 1000 in advanced, and then:

• First try "Mic QPC timestamps" in advanced, this feature is because some microphones delay their audio (or the driver does)
• If that fails, turn that off, see if using a negative "Mic audio offset" in audio settings can help you to manually sync the audio. The max negative is equal to the amount of scene buffering time you're using.
• Optionally, sometimes you have to use "Mic sync fix hack" in advanced in case the mic is "bursting" out its data, but generally it's a last resort and more of a duct-tape solution I implemented for certain computers/devices, should rarely have to actually be used

The audio subsystem is a bit sub-par (currently completely overhauling it in the rewrite as we speak) so mic issues aren't perfect but the tools to fix mic sync are all available if needed.

If it's desktop audio sync, then the only real way to fix that is "sync desktop audio to video timestamps" in advanced. Very rarely some computers will give bad timestamp data for desktop audio (very very rarely) and this option fixes that -- generally I don't recommend it otherwise because it can make desktop audio timing slightly less accurate than if the device was reporting the proper timestamps. This is pretty much always a system issue.

If you get background noise that's usually due to the microphone itself and there's not much you can do about that other than noise gate.

If you get weird buzzing sometimes that can be a motherboard/port thing that means that there's interference with other devices or the motherboard itself on the system.

If you get even more strange static/pops that's almost always definitely due to motherboard/port thing, or USB interference (I have no idea why this happens but it does).

OBS just reads your mic data, it doesn't try to modify it or mangle it, it just reads it.

Still having the same issue, months later. bump

If it's delayed, and you've tried all of the options above, you can manually adjust mic audio time via the "mic time offset" in audio settings. If it's desktop sound you're having issues with (that should -never- be the case) then you need to use "global audio time offset" in advanced. Both of these options can be set with positive numbers if you need the sound to be more forward in time, or negative numbers if you need the sound to be further backward in time, in milliseconds (-1000 for example is backward in time by 1 second).

The amount of negative time offset you are allowed to use is relative to how much "Scene buffering time" you have set in advanced. If you need to set your audio time further backward, increase scene buffering time to compensate.
