Compression Fundamentals

Learn how threshold and ratio control a compressor, triggering gain reduction as signals cross set levels and varying from gentle to aggressive attenuation with higher ratios.

Explore how attack and release shape compression in practice, adjusting fast or slow times, threshold, and ratio to control drum transients and achieve natural-sounding gain reduction with make-up gain.

Learn to fatten a light synthesized snare with compression by balancing threshold, attack, and release to shape its transient and body, including sidechain techniques for space.

Apply fast, high-ratio compression on loud leads, setting the threshold to the lowest peak to squash peaks. Use longer attack and release for a natural, ducked feel.

Explore the compressor sidechain and how external signals and sidechain filters, such as high pass, shape gain reduction and create ducking in drum tracks.

Discover parallel compression by blending dry and compressed signals to shape drums. Route to a bus and adjust threshold, ratio, attack, release, and makeup gain to punch up the mix.

Explore how the knee smooths compression around the threshold and how peak versus RMS detection shapes transients, then compare digital, vintage opto, and studio VCA modes on drums.

Explore multi-band compression by splitting the signal into low and high bands with independent thresholds and attack, then use sidechain filtering and dry/wet blends for precise drum shaping.

Learn kick drum compression techniques, using gates to silence the tail, shaping transients with attack and release, and light EQ boosts to emphasize the transient and room noise.

Explore drums bus compression using isotopes neutron, with sidechain to roll off the base frequencies, then apply parallel compression and glue compressor to gel the kick and snare together.

Apply sidechain compression to duck the bass with the kick as the trigger, using peak mode for fast response, and tune threshold, ratio, attack, and release.

Explore how saturation can serve as an alternative to compression, fattening tiny drum sounds by shaping transients with drive, dry/wet, and width for a louder, fuller envelope.

Master channel compression uses multi-band processing to tighten bass, mids, and highs on the master bus. Apply gain boosts on each band with low ratio and attack to preserve transients.

Build confidence in how compression works by revisiting samples and written notes, master all techniques, and use the assessment to test your retention before finishing.
