Part 1: The commonly-seen noise in the audio

Noise is unwanted sound that ruins your audio recording. When you do audio recording, most of the time you can find audio noise. There are 5 common noises :

  1. Hiss

Hiss happens either by an elevated noise floor or analog source material and hiss could happen too because of low-quality recording equipment and environmental factors.

  1. Hum

Hum is a continuous sound with a low-frequency sound of 40-80 Hz, hum can happen when you don't set the sound equipment properly or electromagnetic interference.

  1. Buzz

Buzz can happen because of ground loops, poor wiring, or other electromagnetic interference.

  1. Crackling

Crackling is discontinuous and non-musical sound, crackling can happen because of the explosive aperture of small airways.

  1. Breathing

Breathing can happen when there is a human or animal breathing close to your recorder when you record the audio.
