Free Mac deconvolution. Impulse responses that work anywhere.
Impulser is a free Mac app that exports impulse responses that can be used anywhere. Capture cabinets or rooms, deconvolve the recording, and export standard WAV/AIFF IRs that load in any convolver — with built-in analysis and audition so you hear the result before you commit.
From sweep capture to usable IR
Impulser keeps reference generation, deconvolution, inspection, and audition in one local macOS workflow.
Easy-to-Use Presets
Pick a Guitar, Bass or Room preset and turn a sine-sweep recording into a usable IR in seconds.
Comprehensive Custom Mode
When a capture needs more care, Custom mode exposes detailed DSP controls — switch between ESS and Wiener engines, tune regularization, and refine the result until the IR is right.
IR Analysis
Each selected IR opens in an analysis pane with metrics, waveform, and decay views — helpful feedback to turn the numbers into something actionable.
Seamless Auditioning
Loop a built-in Drum, Bass DI, or Guitar DI source — or your own audio — through any IR and switch between IRs mid-playback. Compare options without breaking the loop.
Import External IRs
Bring in IRs you already own and audition them in the same workspace. The IR Browser keeps session captures and imported files side-by-side, so you can A/B your work against existing references.
Batch Processing
Run a folder of captures against a single reference and export consistently-named WAV or AIFF IRs in one pass.
Free Utility App
Impulser does not need checkout or a trial flow.
