Assignment 1 Initial Review Delays

Abstract

In many physical acoustic spaces, sound waves will often reflect off surfaces causing a perceived delay to the human ear. These delays have various effects in the physical domain, but are sometimes desired in the digital domain for musical effects, to compliment a post production visual for continuity, or even just to make something sound different and unique. It is important to replicate these delayed sounds in a realistic way and realistic way to let the listener know what is happening, rather than having an unnatural sounding output. By using a mix of acoustical phenomena and digital algorithms, a digital system will be able to take an input signal and replicate some of these sounds caused by a “digital delay”.
