Understanding Noise Cancellation

Before we dive into the nitty-gritty of applying noise cancellation in OBS, it’s important to have a solid understanding of what noise cancellation actually is and how it works.

Noise cancellation is a technique used to reduce or eliminate unwanted background noise that interferes with the desired audio signal. It is particularly useful in environments where ambient sounds, such as air conditioners, fans, or traffic, can cause distractions and degrade the overall audio quality.

There are two primary types of noise cancellation: passive and active. Passive noise cancellation involves physically blocking out external noise through the use of materials like earplugs or noise-isolating headphones. Active noise cancellation, on the other hand, uses electronic processing to analyze incoming audio and generate an inverted sound wave that cancels out the unwanted noise.

In the context of OBS, we are primarily concerned with active noise cancellation techniques. OBS achieves noise cancellation by applying filters to the audio sources. These filters analyze the audio signal in real-time and suppress or eliminate unwanted background noise, resulting in a cleaner audio output.

OBS offers two main noise cancellation filters: noise gate and noise suppression.

The noise gate filter works by setting a threshold level below which the audio will be muted or reduced. This is useful for cutting off low-level background noise, such as microphone hiss or keyboard clicks, but it can also inadvertently cut off parts of the desired audio signal if not properly configured.

The noise suppression filter, on the other hand, is designed to attenuate or remove constant background noise, such as hums or air conditioner noise. It does this by analyzing the audio signal and reducing the volume of frequencies that match the characteristics of the background noise.

Understanding these filters and when to use them is crucial in achieving optimal noise cancellation results. By intelligently combining these filters and adjusting their settings, you can effectively remove unwanted background noise while preserving the clarity and integrity of your desired audio source.

Now that we have a solid understanding of noise cancellation and how it works, let’s explore the key features of OBS and how we can take advantage of them to apply noise cancellation in our recordings and live streams.
