Convolver
Batch convolution of WAV files
There is no macOS version yet. The Windows version is ready to download.
There is no Linux version yet. The Windows version is ready to download.
The installer is not code-signed yet, so Windows SmartScreen may show a warning. Choose “More info”, then “Run anyway”.
What it does
Applies one impulse response, or inverse filter, to many WAV files at once with exact linear FFT convolution. Use it to turn recorded sweeps into impulse responses, or to render audio through a measured room, loudspeaker or reverb.
Exact, linear convolution
Computed with FFTs and zero-padding, so there is no circular wrap-around and nothing is truncated.
Many files, one pass
Add as many recordings as you like and process them all with a single impulse response.
Levels you control
Keep the relative level between files, or normalize each one on its own.
A manual workflow with your own gear
Generate
LogSweepGenerator creates the sweep and its inverse filter as WAV files.
Play and record
Play the sweep and record the result with your own DAW, interface or portable recorder.
Convolve
Convolver combines the recording with the inverse filter and gives you the impulse response.
Use cases
Room impulse responses
Play the sweep in a room, record it with a measurement microphone in your DAW, and convolve the recording with the inverse filter. The result is the room's impulse response, ready for acoustic analysis or a convolution reverb.
Batch processing
Convolve many takes or microphone positions in one pass. With “Maintain relative level between files” on, the level differences between positions are preserved.
Capturing hardware for convolution
Guitar cabinets, loudspeakers, spring and plate reverbs and other gear, turned into impulse responses for convolution plugins.
Auralization and sound design
Render dry audio through a measured room, loudspeaker or reverb impulse response to hear how it would sound there.
Measuring on location with a portable recorder
Play the sweep WAV from any player and record it on a field recorder. No laptop is needed at the measurement point; process the files later.
