Noise reduction is an essential part of audio production. It involves using various methods and technologies to reduce unwanted sounds while preserving desired sounds. This process can be applied in post-production sound editing or as a part of a mixing workflow. It can help remove background noise and make recordings clearer, which is essential for achieving great-sounding mixes. Noise reduction can either subtract or attenuate background noise so that the desired sounds stand out more clearly. Techniques vary depending on the desired application and end result; however, those looking to achieve crystal clear sound will find many solutions available through noise reduction in audio production.
