Delay and echo effects
Adobe Audition has three echo effects with different capabilities. All delay effects store audio in memory and then play it back later. The time that elapses between storing and playing the audio is the delay time.
Delay
The Delay effect simply repeats the audio, with the repeat’s start time specified by the delay amount.
Stereo audio has separate delays for the left and right channels, whereas mono audio has a single set of controls.
Analog Delay
Before digital technology, delay used tape or analog delay chip technology. These produced a grittier, more colored sound compared to digital delay. The Analog Delay in Audition provides a single delay for stereo or mono signals and offers three delay modes:
Tape (slight distortion)
Tape/Tube (crisper version of tape)
Analog (more muffled)
Analog Delay simply repeats the audio with the start time of the repeat specified by the delay amount. Unlike the Delay effect, Analog Delay includes separate controls for Dry and Wet levels instead of a single Mix control.
Choose File > Close All. Don’t save any changes. Choose File > Open, navigate to the Lesson04 folder, and open the file Drums110.wav.
In any Effects Rack insert, click the right arrow, and then choose Delay and Echo > Analog Delay.
Set Dry Out to 60%, Wet Out to 40%, and Delay to 545 ms. Feedback determines the number of repeats as they fade out. Start playback. No Feedback (a setting of 0) produces a single echo, values moving toward 100 produce more echoes, and values above 100 produce “runaway echoes.” (Watch your monitor volume!)
With feedback at 40, set the Trash control (which increases distortion and boosts low frequencies, adding warmth) to 100. Change the different modes (Tape, Tape/Tube, Analog) to hear how each affects the sound. Vary the feedback, being careful to avoid excessive, runaway feedback.
Spread at 0% narrows the echoes to mono and at 200% produces a wide stereo effect. Play with the various controls, and you’ll hear anything from dance mix drum effects to ’50s-style sci-fi movie sounds. Keep Audition open for the next lesson.

Echo
The Echo effect allows for tailoring the echoes’ frequency response by inserting a filter in the delay’s feedback loop, where the output feeds back to the input to create additional echoes. As a result, each successive echo processes each echo’s timbre to a greater degree. For example, if the response is set to be brighter than normal, each echo will be brighter than the previous one.
