Assigning Input and Output Hardware

You need to set up the audio input and output device in the Hardware I/O Assignment area before you can use Impulse Response Utility.

Figure. Audio hardware input and output parameters.

The audio input selection determines the audio device used to record audio tracks. The audio output selection determines the audio device used to monitor the recorded signal, and to play back the generated sine sweep.

To select an audio input device
  • In the Audio Input pop-up menu, choose an audio interface driver.

To select an audio output device
  • In the Audio Output pop-up menu, choose an audio interface driver.

Note: Although the Hardware I/O Assignments area also displays the current sample rate, you cannot change the sample rate of your impulse response project in Impulse Response Utility. If you want to record your audio tracks at a different sample rate, you will need to change it in the Audio MIDI Setup utility, or in the software for your audio interface (if applicable). Consult the documentation for your audio interface if you’re unsure.
