Best for material with clear attack transients, such as drums
40
describe the monophonic Elastic Audio Processor:
Best for mono material, such as vocals and bass guitar
41
describe the varispeed Elastic Audio Processor:
Links time and pitch changes for tape-like speed change effects
42
what is the The X-Form Processor?
Highest quality time compression algorithm | Rendered only
43
describe Real-Time Versus Rendered Processing:
Real-time is immediate, but is demanding on resources Rendered is slower, but reduces processing load
44
how do you Enable Elastic Audio?
