Audio compression is the reduction of the dynamic range of an audio track by attenuating the loudest parts and raising the volume of the quietest parts of the audio signal. This is often used to smooth out instruments that are too loud or too soft or fall outside the recording equipment's dynamic range.What does audio compression do?
Audio compression is the process of reducing the dynamic range of a sound. This compression occurs when the volume level signal exceeds a specified level. In practical terms, when a singer decides to belt out the chorus, instead of jumping for the fader, the compressor does the work for you.How does audio compression work?
The goal in audio compression is to reduce the number of bits required to accurately reproduce an analog sound. The first process we’ll look at is called “lossy.” Lossy compression is a one-way technique that throws away non-critical data to save space.
