Impulse Response Utility overview
Impulse Response Utility is a multitrack audio recording and deconvolution application. With this app, you can create impulse response files for the Space Designer convolution-based reverb effect. For information about Space Designer, see Logic Pro Effects. Although Space Designer provides numerous great-sounding halls, delays, and other reverbs, you might want to create an impulse response of your own studio, kitchen, bathroom, or even teapot.
You are not limited to creating impulse responses of rooms and spaces. You can make an impulse response from any device that you can play a broadband sine sweep into and record the results. Two examples are guitar speaker cabinets and hardware processing devices, such as tube equalizers and reverb effects units.
Impulse Response Utility provides all the tools needed to create an impulse response, such as a flexible sweep generator, powerful editing facilities, and one-click creation of Space Designer settings. All you need is your computer, Impulse Response Utility, and an audio interface that is connected to speakers and microphones.
All the parameters and functions that you need to create impulse responses are contained in a single window. The Audition window in Impulse Response Utility allows you to further test your impulse response recordings before creating Space Designer settings.
The Impulse Response Utility interface is divided into four areas:
Hardware I/O Assignment area: Contains pop-up menus that let you choose the audio input and output devices, as well as the sample rate. See Set up audio I/O and monitoring in Impulse Response Utility.
Monitor, Sweep, and Process section: Contains monitoring and sine sweep generation parameters, plus buttons to deconvolve your audio tracks into an impulse response, and audition your impulse response. See Sweep generator in Impulse Response Utility.
Inputs/Track section: Lists all audio tracks used for your impulse response recordings. See Audio track parameters in Impulse Response Utility.
Editing area: Displays audio information for the currently selected audio track. See Edit your impulse response in Impulse Response Utility.
