IR Capture Free

IRCapture is an application used to measure impulse responses. You can use IRCapture to measure the room reverberation of acoustical spaces, or to measure digital effects units, speaker cabinets, spring or plate reverbs, etc. The impulse responses from IRCapture can be loaded into our ConvologyXT plug-in to reproduce the measured system.

There is no purchase or registration required.

On MacOS, IRCapture is distributed as a package installer in a DMG file. Open the DMG and then double-click on the PKG file to run the installer. On Windows, IRCapture is distributed as a zip archive containing the application and a PDF manual.

After installing, run the application and select Audio Settings to select the playback and recording devices. After selecting the audio devices, click Start to begin the measurement. The app will play a sinusoid sweep, and will then write the measured impulse response to the file “impulse.wav”. At this point one generally repeats the measurement a few times while tweaking the output and input levels to get a good record level. When the levels are correct you can examine your impulse response in a sound editor, or load directly into Convology XT.
