Introduction

Audio quality is a critical aspect of any content creation, whether you’re streaming on Twitch, recording a YouTube video, or conducting a virtual meeting. OBS Studio, a popular and free broadcasting software, provides powerful tools for improving your audio. In this tutorial, we’ll walk you through the process of applying audio filters in OBS Studio to enhance your audio quality and deliver a more professional and enjoyable experience to your audience.

Step 1: Download and Install OBS Studio

1. If you haven’t already, download and install OBS Studio from the official website (https://obsproject.com/).
2. Launch OBS Studio once the installation is complete.

Step 2: Add Your Audio Source

1. In the OBS Studio main window, locate the “Sources” panel at the bottom.
2. Click the “+” button to add a new source, and choose “Audio Input Capture” or “Audio Output Capture” based on your needs. For most users, “Audio Input Capture” is the appropriate choice.
3. Name your audio source, then click “OK.”
4. In the next window, select the audio device you want to capture. This is usually your microphone or another audio input source.

Step 3: Apply Audio Filters

1. After adding your audio source, right-click on it in the “Sources” panel, and select “Filters.”
2. In the “Filters” window, click the “+” button to add a new audio filter.

Step 4: Configure Audio Filters

Now, let’s explore some common audio filters and how to configure them:

a. Noise Suppression:

• Filter Type: Select “Noise Suppression” from the drop-down menu.
• Configure Strength: Adjust the slider to control the strength of noise suppression. Start with a moderate setting and fine-tune as needed.
• Click “Close” to apply the filter.

b. Noise Gate:

• Filter Type: Choose “Noise Gate” from the drop-down menu.
• Set Threshold: Adjust the slider to set the threshold at which the microphone should start picking up audio. Lower values make the microphone more sensitive.
• Set Attack Time: This controls how quickly the gate opens when you start speaking.
• Set Hold Time: The hold time determines how long the gate stays open after you stop speaking.
• Set Release Time: This controls how quickly the gate closes after you stop speaking.
• Click “Close” to apply the filter.

c. Equalization (EQ):

• Filter Type: Select “VST 2.x Plugin” or “VST 3.x Plugin” if you have a third-party EQ plugin, or choose “Graphic EQ” for basic equalization.
• Configure the EQ settings based on your preferences. For a graphic EQ, click and drag the sliders to adjust frequencies.
• If you’re using a VST plugin, click the “Browse” button to locate and load your plugin.
• Click “Close” to apply the filter.

d. Compressor:

• Filter Type: Choose “Compressor” from the drop-down menu.
• Configure the settings as follows:
  • Threshold: Set the level at which compression starts.
  • Ratio: Determine the compression ratio (e.g., 2:1).
  • Attack Time: Adjust the attack time for how quickly the compressor responds.
  • Release Time: Control how long it takes for the compression to release.
• Click “Close” to apply the filter.

Step 5: Test and Fine-Tune

1. After applying filters, it’s essential to test your audio and make adjustments as needed.
2. Monitor your audio by speaking into your microphone or playing a test audio file while observing the audio levels in OBS Studio.
3. Adjust filter settings as required to achieve the desired audio quality.

Step 6: Save and Stream/Record

1. Once you’re satisfied with your audio quality, you can save your OBS Studio settings as a profile for future use.
2. To stream or record with your improved audio, set up your scenes and sources as usual and click the “Start Streaming” or “Start Recording” buttons.
