Part 1. Why Is OBS Audio Out Of Sync?

The main problem of most streamers is when their audio is out-of-sync, it seems okay at the first couple of minutes but begins to have an audio delay that doesn't match the opening of your lips in the next hour. In desperation to fix the uncertainty of the stream, some will go to the advanced audio properties to adjust the sync offset that can only enter a delay for the audio source in a certain amount of time, which is not advisable. Instead, why OBS audio is out of sync is because of the sample rate mismatch.

Part 2. 7 Easy Steps to Fix OBS Audio Delay

The audio delay happens on any occasion; it can be in streaming platforms, recorded presentations, and even live broadcasts. Most of the reason this happens is the connectivity issues, technical difficulties, and faulty programmed applications. For instance, you're using the OBS studio as a platform for your streaming activity, and it happens that every video output you stream has some delay. Good thing that there are perfect ways to prevent these situations using the same platform. Here are the easy-to-follow steps:

Step 3: Choose an Appropriate Sample Rate

Edit the sample rate based on the preferred sample rate of your desktop and recording devices. Suppose your recording device is a bit ancient, and you have an old setup. In that case, it will be better to lower the sample rate from the standard sample rate of 48 kHz and increase its adjustment from 48 kHz if you want to observe your device's preferred sample rate. Because the higher the video's sample rate increases, the closer it will recreate the original audio. Furthermore, you can only change the channels option depending on what tool you use to play the video.

Part 4. FAQs About OBS Audio Delay

What is a sample rate mismatch?

The audio sample rate, expressed in kilohertz, is the speed at which the system takes these measurements. The audio sample rate determines the frequency range you can capture in digital audio—the sample rate changes in your audio preferences in most DAWs. Changing the sample rate affects the quality of your audio. However, sample rate mismatch is an unequal receiving and sending audio sample rate to the source. This incident always happens if the speaker output and the headphone output are not the same sample rate causing an audio delay.

Do I lose the quality of the audio if I adjust the sample rate?

The sample rate is changing if you want to listen to the audio in your video clip and not change it. In using the FVC Video Converter Ultimate, you will only change the audio delay of the video clip to sync its audio. You will not adjust the sample rate anymore and be afraid of losing the audio quality.

What sample rate is preferred if I use low-quality audio output?

The quality of audio depends on the audio output. If your microphone or speaker only supports a low-frequency audio rate, it's better to lower the standard sample rate to 44.1 kHz than to set it to 48 Hz. The sample rate may affect the audio sync delay if there's no equal frequency flow to output and input.


To summarize, the audio delay that always appears in OBS Studio is open in different ways to fix it. We discussed the sample rate mismatch and observed different audio outputs but the best way to show a solution to make the audio out of sync is to use the FVC Video Converter Ultimate. Aside from its feature that can fix audio sync, it has many more features that can help improve your video clip.
