Attack / Release Time Calculator
BPM-synced compressor attack and release times for every source, with animated GR envelope visualizer.
About the Attack / Release Time Calculator
The Attack / Release Time Calculator is a free interactive tool for music producers who want accurate answers fast. Whether you're searching for compressor attack release calculator BPM, attack release time by source, BPM synced compressor settings, this tool gives you real-time results without leaving your browser — and explains the reasoning behind every value so you know what to do with it.
Every tool on MusicProductionWiki is built around one principle: answer the question and explain the reasoning. The Attack / Release Time Calculator not only calculates — it shows you why those values work, what changes when you adjust them, and what professional producers do differently across genres.
This tool is part of the Dynamics & Compression category. It's embedded directly inside the relevant entries in The Producer's Bible — MPW's comprehensive reference library — where it appears in context alongside the theory that explains why each setting works the way it does.
All tools on MusicProductionWiki are free, require no login, and work in any modern browser on desktop or mobile.
Frequently Asked Questions
How do I calculate compressor attack time from BPM?
Divide 60,000 by your BPM to get the length of one beat in milliseconds. A fast attack for drums at 120 BPM might be 1–5ms. A slow attack that lets the transient through might be 30–80ms. This tool calculates tempo-relative values for any source automatically.
What attack time should I use for drums?
For punchy drums that retain their transient, set attack to 10–30ms. This lets the initial hit pass before compression kicks in. For a more squashed, dense sound, use 1–5ms. The right setting depends on the snare and kick character you are working with.
What release time avoids pumping?
Pumping occurs when the compressor releases too slowly and audibly reacts to the rhythm. Try auto-release if your compressor has it, or set release to recover in less than one beat — at 120 BPM, that is under 500ms. Faster release (100–200ms) works well on drums; slower (300–600ms) suits vocals and buses.
