Time-Based Effects - Posted on 2017-03-13 by Corrine Selden

Here are a few highlights from what I learned about time-based effects in Chapter 15:

• A delay, when applied to an audio signal, stores the audio signal and plays it back at a given time interval. 
• Feedback is achieved by fedding the delayed signal back into the input of the delay device. 
• You hear phasing with a short delay of 0 to 1 msec with feedback. 
• Chorusing can also be described as Doubling. 
• Flanging occurs when the feedback is turned up, and the delay time set below 30 msec.
• Density, in the context of Reverb, is equal to the intensity of the reverb. 
• Decay typically means the amount of time is takes for the reverberated signal to fall back down. 
• Pre-delay, in the context of Reverb, is the amount of silence before the Reverb kicks in. 
• Spring a type of reverb created within a small metal coil. 
• Time-based effects can add depth and a sense of space. 
• Early reverb was created by sending sound into an echo chamber, and then recording that signal and returning it on a separate channel in the mix. 
• A traditional phaser effect is achieved by using a series of notch filters that sweep the frequency spectrum. 
• A reverb is really a series of delays.
