What's the difference between reverb, echo, and feedback?
http://en.wikipedia.org/wiki/Reverberation
Reverberation is the persistence of sound in a particular space after
the original sound is removed.[1] A reverberation, or reverb, is
created when a sound is produced in an enclosed space causing a large
number of echoes to build up and then slowly decay as the sound is
absorbed by the walls and air.
http://en.wiktionary.org/wiki/echo#Noun
A reflected sound that is heard again by its initial observer.
http://www.thefreedictionary.com/feedback
Sound created when a transducer such as a microphone or electric
guitar picks up sound from a speaker connected to an amplifier and
regenerates it back through the amplifier.
Or, in an electrical circuit, when the voltage or current at a point in
the circuit is "fed back" to a point earlier in the circuit. Depending
on its phase, this can be either negative or positive feedback.
