Adobe Audition

Objective: Use Audition to create test tones that you can use to check the frequency response of various devices in your studio, such as speakers.Background: Audition can generate tones, noise, and DTMF signals. We’ll use that capability to create a sine-wave test tone that sweeps logarithmically from 20Hz to 20kHz over a 20-second period.
