What is parallel compression?

Parallel compression, also known as New York compression, is a technique used in audio production to achieve a more dynamic and powerful sound. This technique involves duplicating an audio signal, applying heavy compression to the duplicate, and blending it back in with the original signal.

The primary benefit of parallel compression is that it allows for the desired level of compression to be applied to a signal without completely squashing the dynamic range. By blending the compressed signal back in with the original, the peaks of the signal are still preserved while the overall sound is fattened and brought forward in the mix.

Parallel compression can be applied to individual tracks such as drums, vocals or guitars, or to entire mixes. It is commonly used in genres such as rock, pop, and electronic music to add depth, punch, and clarity to the sound.

To set up parallel compression, simply duplicate the track you want to compress, add a heavy compressor with a low threshold and high ratio to the duplicated track, and blend it back in with the original using a mixer or fader. Experiment with different settings and blending ratios to achieve the desired effect.
