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 or source present during the initial recording phase. For example, a guitar track recorded with a clean tone can be reamplified through a high-gain tube amp to achieve a distorted sound. Similarly, a vocal can be sent through a vintage compressor or a tape machine to add character and subtle coloration. Reamplification offers a high degree of flexibility, enabling producers to experiment with different amplifier and effects combinations after the original performance has been captured. It requires careful setup to ensure the signal is routed correctly from the playback device to the amplifier and then to the re-recording interface.
