Optimal OBS Audio Settings for Twitch

Most streamers cannot afford to rent a professional studio each time they go live, so it is not surprising that many encounter sound issues during their streams.

At times, it is too low; at other times, it is too high.

They go through extensive trial and error to determine the best settings and address the issue of low Twitch volume.

If you are facing the same issues, I have a few tips—here are the optimal OBS mic settings.

1. Adjusting the settings on your computer

Before launching OBS and adjusting the settings, let's concentrate on the changes you need to make in your PC settings.

If you haven't yet connected the microphone you intend to use during the stream to your PC, please do so now, and then continue reading.

First, you need to open the Sound settings on your computer.

You should see the microphone listed alongside other devices that your PC is using as a sound source.

Select the microphone, then open Properties.

Tweaking the settings on your computer

A new window should appear, displaying several different tabs. For now, let's concentrate on the Levels.

There isn't a specific rule for selecting the levels of your microphone, but based on my experience, I recommend that anything between 70 and 80 is ideal.

You can now close this tab and open OBS.

2. Audio Filters

You can locate the audio Filters in the Audio mixer.

Noise Suppression

Now, either right-click on the screen or tap the “+” icon to choose Noise suppression.

Noise suppression

This feature allows you to effortlessly eliminate any unwanted background noise, such as traffic sounds or the noise from a fan in your room.

The level of noise suppression is expressed in dB.

To begin, select -10 dB and verify whether the unwanted sounds have been eliminated.

If they are not, lower the level further and conduct constant testing to determine at which point the noise is no longer detected by the mic.

Noise Gate

Now, it is time to add another filter, which is the Noise gate.

This filter has a feature similar to that of noise suppression. It further aids in eliminating unwanted sounds. If an alarm goes off during the stream, the noise gate will ensure it is removed, allowing your audience to watch the stream without distractions.

Noise gate

There are two meters you need to adjust - I will first discuss the Close Threshold.

To set the level, speak very softly into the mic. Ensure that you are using a natural tone while doing so—a tone you would likely use during the stream.

Speak into the microphone and gradually adjust the Close Threshold levels to determine at which setting you can no longer hear your voice.

Now that you’ve established the value for Close Threshold, selecting the value for Open will be straightforward.

This value should be just a few decibels higher. For instance, if the value for Close is -40 dB, the level for Open should be -38 dB.

Compressor

The compressor performs the opposite function of the noise gate and noise suppressor; therefore, it can assist you in addressing the issue of the OBS mic volume being too low.

Compressor

Even if you've already set a relatively high level for your microphone in Windows settings, the sound may still require a slight boost, and the compressor will enhance mic volume in OBS.

Additionally, the issue of audio distortion on Twitch will also be addressed.

There are a few adjustments you need to make here:

Limiter

This is the final component; together with the compressor, it ensures that the microphone sound is never excessively loud.

Limiter

For release time, do not exceed 100 ms.

For Threshold, begin at 0 and continue speaking loudly; this is the only method to establish the correct value.

A Few Additional Tips

Some issues arise from the improper use of equipment, specifically the microphone. Here are a few additional tips:

1. Check which side of the microphone you are using.

Every microphone has two sides, so low sound levels may result from speaking at the wrong angle or into the back of the mic.

2. Check the distance

Unwanted noise can result from not maintaining the proper distance from the mic.

The microphone will capture more background noise if you are positioned too far away from it.

If you are positioned too close to the mic, the audio will become more distorted.
