reamplification
Reamplification, also known as reamping, is a post-production audio technique used in music and sound design. It involves sending a recorded audio signal, typically from a digital source like a DAW, back out into an analog amplifier and then re-recording the resulting sound. The primary purpose of reamplification is to impart the sonic characteristics of the analog equipment, such as the warmth, saturation, or distortion of a guitar amplifier or a specific outboard effects unit, onto a previously recorded dry signal.
This process allows engineers to achieve a desired analog tone without needing to have the original instrument
