Noise is an inevitability when recording in an untreated space or with budget equipment. However, there is software that can remove buzz from audio regardless of whether you were successful in removing buzzing from the mic or not. Scroll down to discover the five best software to remove buzz from the audio on Mac and Windows. But first, let's understand what buzz is and is buzz caused.
Part 1: What Is Buzz In Audio?
Well, in technical terms, Buzz is a superposition of the harmonics of the 60Hz (like 120Hz, 180Hz, etc) mains AC frequency on the audio signal. In simple terms, it is caused because of bad wiring, defective equipment, or just a noisy electronic environment. Here are the three prominent reasons why buzz is caused:
- Interchassis currents result from the stray connection in the power supply. The recording instruments might not be adequately connected. Thus, causing the superposition of the harmonics.
- Ground loops, i.e., the difference between the voltage between the interconnected instruments.
- And the prominent one is the electromagnetic coupling, which is the result of poor AC and signal connections.
Now that you understand what buzz is. And the reasons for it to be visible in the audio signals. Let’s discover the tools which can eliminate these noises.
