It details noise suppression, noise gate, compressor, and limiter settings, plus monitoring and sync tips, and stresses the importance of test recordings before going live. ### Key Points - **Video goal** [00:01] — The video promises the best OBS audio settings for streaming and recording in 2026, fixing common audio problems. - **Sample rate** [00:05] — Set the sample rate to 48 kHz, which matches Twitch, YouTube, and most capture cards to help prevent audio issues. - **Channels** [00:14] — Set the audio channels to stereo. - **Desktop audio device** [00:17] — Under desktop audio, select your headphones — the audio your audience will hear. - **Microphone device** [00:26] — Under mic/auxiliary audio, set your actual microphone, not the default device — using the wrong device is a common mistake. - **Noise suppression** [00:38] — Add a noise suppression filter: use RNNoise if your PC can handle it (removes hiss/room noise well), or Speex for weaker PCs. - **Noise gate** [00:52] — Set the noise gate background noise and open threshold just below your normal speaking volume, so the mic stays quiet when you're not talking but sounds natural when you are. - **Compressor values** [01:07] — Starting compressor values: threshold -18 dB, ratio 4:1, attack 10 ms, release 100 ms, output gain +2 dB. - **Compressor purpose** [01:19] — Compression makes quiet parts louder and loud parts controlled, so your voice stays even and clear. - **Limiter** [01:24] — Add a limiter with threshold at -1 dB to prevent clipping when you laugh, shout, or get excited on stream. - **Monitoring and sync** [01:45] — In advanced audio properties, set monitoring to off to avoid echo/delay; leave sync offset at 0 ms for most setups. - **Test recording** [02:03] — Always do a test recording before going live or recording: talk normally, get loud for a second, then listen back to confirm consistent levels. ### Conclusion With a 48 kHz stereo setup, the right device selection, the four-filter chain (noise suppression, gate, compressor, limiter), monitoring off, and a quick test recording, you can achieve clean, consistent stream audio in about two minutes. ## Transcript sound [music] clean, this video fixes that. These are the best OBS audio settings for streaming and recording in 2026. Let's get into it. First, [music] go to settings, then audio. Set your sample rate to 48 kHz. This matches Twitch, YouTube, and most capture cards to help prevent audio issues. Then, set your channels to stereo. Now, under desktop audio, select your headphones what your audience is also hearing. Under mic/ axiliary audio, make sure to set your actual microphone and not default. Using the wrong device is one of the most common mistakes. Once that's set, click apply. Now we're setting up filters. This is where your audio really and go to filters. First, we're going to add noise suppression. If your PC can handle it, use RN noise. It removes background hiss and room noise without killing your voice. If your PC is weaker, spex works, too, but RN noise This stops your mic from picking up sound when you're not speaking. Set your background noise. Then set your open threshold just below your normal things quiet when you're not talking, but natural when you are. Now add a at a constant volume so it's not too quiet or too loud. Here are some solid starting values. Threshold at 18 dB, ratio 4:1, attack at 10 ms, release at 100 ms, and output gain at plus 2 dB. In simple terms, compression makes quiet parts loud and loud parts controlled so your voice stays even and clear. The last filter we'll be adding is limiter. Set the threshold to negative 1 dB. This prevents clipping if you laugh, shout, or get excited on stream. So, every mic if you're finding this video helpful so far, be sure to drop a like and helps my channel. All right, now let's get back into the video. Now, click on the gear icon next to your mic and open advanced audio properties. Make sure your mic is set to monitor off unless you know you need monitoring. Monitoring incorrectly can cause echo or delay. If your audio ever feels out of sync, this is also where you can adjust sync offset. For most people, leaving it at 0 m is perfect. Finally, before you go live or record, always do a test recording. Talk normally, get loud for a second, and then listen back to it. If consistent, you're good to go. So, those are the best OBS audio settings for streaming and recording in 2026.
