One of the main issues that content creators face is that their audio becomes out of sync with the rest of the stream over time on social media networking sites. For instance, your mic audio may initially sync up with your lips, but after a few minutes, there will be a conspicuous offset from the video. Fortunately, most audio sync issues in OBS are caused by a sample rate imbalance. Learn how to fix OBS audio delay by reading today's article.

OBS Audio Delay

Part 1. Reason for OBS Audio Delay

As a general rule, the video takes significantly longer to complete and encrypt within OBS than audio. This can lead to the audio playing ahead of or behind the video on occasion, giving rise to a frustrating delay that makes the watching experience a little inconvenient for some viewers. A computer's inability to complete this process, as with most technical problems, can be attributed to various factors. One area to check for is whether all of the sound devices on your system are set to either 48 or 44.1 kHz, which seem to be the two sample rates that OBS supports. Find out what sample rate you're using in the Audio Settings section of OBS and double-check that everything else matches up in the sound settings panel on your computer.

Part 2. Troubleshoot OBS Audio Delay

1. Check the Sound Setting

This problem can be resolved by making sure every single sound device on your system is set to either 48 kHz or 44.1 kHz, which are the two sample rates that OBS Studio claims to support. Here are the methods to fix it.

Step 1

Select the Settings button in OBS Studio.

Step 2

To open the Audio Settings window, click on Audio. You must first access audio settings to determine the sample rate your sources must be adjusted.

Step 3

Check the chosen sample rate. If you have an old audio device connected, you may need to change this value to 44.1 kHz. Alternatively, it is acceptable to leave the frequency at 48 kHz.

Step 4

Locate the Sound Setting on Windows 10. Hit the Sound Control Panel > Properties. Next, hit the Advanced tab and ensure that all of your devices are set to the same sample rate as you did in Step 3.

Step 5

Finally, choose the highest variant of Hz that corresponds to the sample rate setting on your OBS.

2. Fix the Issue Using the Advanced Audio Properties on Windows

If you are using an external microphone, there may be a lag in the audio when it is being watched on channels. OBS can compensate for this by including a delay during the encoding process. Here is the way to do so to fix OBS audio out of sync.

Step 1

On the OBS Audio mixer, select your audio source by clicking on the gear icon next to it.

Step 2

Hit Advanced Audio Properties. Increase the negative offset of your audio source (500ms = 0.5 seconds). A negative balance will correct the issue with delayed audio.

3. Improve the Audio Delay using Sync Offset on Mac

In some cases, it is a must to add an audio delay to sync the video from a camera with the audio from a mic. It's pretty simple actually to do, but the choice to add an audio delay isn't prominently displayed in OBS. Let us know the methods by following the steps below.

Step 1

Insert an audio source or a microphone into your project.

Step 2

elect an audio source by clicking on the cog next to it in the mixer.

Next, specify the length of time that the audio will be delayed. Enter a delay for the audio source in milliseconds under the audio mixer's Sync Offset (ms) column. One second is equal to 1000 milliseconds. This option may require trial and error before the audio and video are appropriately synced together.

Part 4. FAQs of OBS Audio Delay

1. Is it possible to record the last 5 minutes with OBS?

The estimator can only give you a rough idea of the approximated RAM usage of your default setup. OBS will have to write the buffer to disk if you run out of RAM, which is not the most efficient solution. Five minutes or even a little longer should be no issue for most people in most situations.

2. Is 8GB of RAM sufficient for OBS?

Yes. You will not give the best video content quality with only 8GB of RAM, but this amount of memory should be sufficient to stream some relatively low gameplay quite comfortably.

3. Where can I find recorded videos in OBS?

OBS automatically saves outputs to your Video folder, which is located in the primary documents section of your computer. Clicking on File > Show Recordings will take you directly to this location the fastest. Hit Settings from the drop-down menu at the bottom right, then the Output tab, followed by the Recording tab.
