Reference sweep
The exponential sine sweep you played through the system. Use your own file or generate one below.
Drag the handles to trim the sweep region. The start point is copied to every microphone track.
Microphones
Add microphones or drop several files at once. Each mic is named after the first word of its file, and matching L/R files are linked into a stereo pair automatically.
Processing & export
Choose how the impulse responses are cleaned up and delivered.

Sweep generator
Don't have a sweep yet? Generate a high-quality exponential sine sweep to play through your system.
Play this sweep through your system at a steady level, record every microphone, then load the recordings above. Longer sweeps give a better signal-to-noise ratio.
How impulse response deconvolution works
An impulse response (IR) captures how a space, speaker cabinet or microphone colours sound. Instead of firing an impossible perfect impulse, engineers play a controlled exponential sine sweep and record the result. IR Maker recovers the impulse response by deconvolving the recording against the reference sweep using a regularized inverse filter, which stays stable outside the sweep band and rejects out-of-band noise.
The optional noise stage uses phase-preserving spectral subtraction: it estimates the steady hum and room-noise spectrum and removes it from each recording while leaving the phase untouched, so the resulting IR keeps its true transient and stereo image. Results export as individually named WAV files in a ZIP, or as a single multitrack WAV.
100% local & private. All decoding, deconvolution and export happens in your browser. Nothing is uploaded to any server.
Ableton rack export. Choose the Ableton rack format to receive a ready to use Audio Effect Rack (.adg) with one convolution chain per microphone plus a Samples folder. Unzip it, drop the .adg into Live, and blend your mics. The chains use the free Convolution Reverb Pro device, so install that Ableton pack first.
