Are you tired of background noise ruining your live streams and recordings? Do you want to ensure that your audience focuses on your content rather than the distracting sounds behind you? Look no further! In this article, we’ll dive deep into the world of noise suppression and explore how to add it to OBS (Open Broadcasting Software), a popular platform for live streaming and recording.
What Is Noise Suppression, And Why Do You Need It?
Noise suppression, also known as noise reduction or noise cancellation, is a technique used to minimize or eliminate unwanted background sounds in audio recordings. This can include anything from keyboard typing, mouse clicks, and air conditioning humming to background chatter, traffic noise, and other ambient sounds.
In a live streaming or recording context, noise suppression is essential for several reasons:
- Improved audio quality: By reducing background noise, you can ensure that your audience focuses on your voice, music, or other desired audio elements.
- Enhanced listener experience: A clean and clear audio signal can significantly improve the overall viewing experience, making it more engaging and immersive.
- Professionalism: Noise suppression can help you appear more professional and polished, which is especially important for businesses, educators, and content creators who want to establish credibility.
Hardware Vs. Software Noise Suppression
Before we dive into adding noise suppression to OBS, it’s essential to understand the two primary methods of noise suppression: hardware and software.
Hardware Noise Suppression
Hardware noise suppression involves using specialized equipment, such as:
- Microphones with built-in noise suppression: Some high-end microphones, like the Blue Yeti or Rode NT-USB, have built-in noise suppression capabilities.
- Noise-reducing microphone accessories: Devices like pop filters, windscreens, or shock mounts can help reduce plosives, wind noise, and vibrations.
- External audio processors: Standalone audio processors, like the DBX 286s, can be used to reduce noise and improve audio quality.
Software Noise Suppression
Software noise suppression, on the other hand, relies on algorithms and digital signal processing techniques to reduce noise. This method is typically more accessible and affordable than hardware solutions.
In the context of OBS, we’ll focus on software noise suppression using plugins and filters.
Adding Noise Suppression To OBS
Now that we’ve covered the basics, let’s explore how to add noise suppression to OBS using various plugins and filters.
VST Plugins
OBS supports VST (Virtual Studio Technology) plugins, which can be used to add noise suppression capabilities. Here are a few popular VST plugins for noise suppression:
- Noise Reduction 2: A free VST plugin that offers advanced noise reduction algorithms.
- Noise Gate: A paid VST plugin that allows for customizable noise threshold and attack/release times.
To add a VST plugin to OBS:
- Download and install the VST plugin of your choice.
- Open OBS and navigate to Settings > Audio.
- In the Mic/Auxiliary Audio Device section, select the VST Plugins option.
- Browse to the location where you installed the VST plugin and select it.
- Adjust the plugin’s settings to taste.
OBS Filters
OBS offers built-in filters that can help reduce noise. Here are two filters you can use:
- Noise Gate: A simple filter that allows you to set a noise threshold and attack/release times.
- Expander: A filter that can help reduce background noise by automatically adjusting the volume.
To add an OBS filter:
- Open OBS and navigate to Settings > Audio.
- In the Mic/Auxiliary Audio Device section, select the Filters option.
- Click the + button to add a new filter.
- Select the desired filter (Noise Gate or Expander) and adjust its settings as needed.
Configuring Noise Suppression Settings
Once you’ve added a VST plugin or OBS filter, it’s essential to configure the noise suppression settings to optimize performance.
Threshold And Sensitivity
The threshold and sensitivity settings determine when the noise suppression algorithm kicks in. A lower threshold means the algorithm will activate more easily, while a higher sensitivity setting will allow more subtle noise reduction.
Attack And Release Times
Attack and release times control how quickly the noise suppression algorithm responds to changes in the audio signal. Faster attack times can help reduce sudden noise spikes, while longer release times can help maintain a consistent audio level.
Frequency Response
The frequency response setting determines which frequencies the noise suppression algorithm targets. This can be useful for reducing specific types of noise, such as low rumble or high-pitched squeaks.
Experiment with different settings to find the optimal balance between noise reduction and audio quality.
Troubleshooting Common Issues
When using noise suppression in OBS, you may encounter some common issues:
Audible Artifacts
If you notice audible artifacts, such as robotic or “underwater”-sounding audio, adjust the noise suppression settings to reduce the aggressiveness of the algorithm.
Over-Suppression
If the noise suppression is too aggressive, it may affect the desired audio elements. Try reducing the threshold and sensitivity settings to find a better balance.
Incompatibility With Other Plugins
If you’re using multiple VST plugins or OBS filters, ensure they’re compatible with each other. You may need to reorder the plugin/filter chain or adjust individual settings to achieve optimal performance.
Conclusion
Noise suppression is a critical component of high-quality audio in live streaming and recording. By understanding the different methods of noise suppression and adding it to OBS using VST plugins or built-in filters, you can ensure a more engaging and professional audio experience for your audience. Remember to experiment with different settings and troubleshoot common issues to find the perfect balance for your specific needs.
Happy streaming and recording!
