What is Parallel Compression?
Parallel compression is an audio processing technique where a compressed version of a signal is blended with the original uncompressed signal. This allows the mix to retain the natural dynamics of the original audio while adding the power and density created by compression.
In this technique, the audio signal is split into two paths. One path remains unchanged, while the other is processed with heavy compression. The compressed signal is then mixed back together with the original signal to achieve a balanced result.
Parallel compression is commonly used in drum mixing, vocal processing, and full mix buses to add punch, sustain, and presence without making the sound overly squashed. It is sometimes referred to as “New York compression” in music production.
