Restoration for Audio

 

Audio restoration is similar to audio enhancement as they both clean up a file using a D.A.W. and professional tools to achieve this goal.

 

One difference is that restoration is often used when taking analog recordings (reel-to-reel, cassette, micro-cassette) and creating a digital file of them.

Analog tape generally has a specific hum to it due to the actual recording process of the machine used to capture the audio.

 

A static-like sound is created by the movement of the tape through the machine.

 

The electricity running through the machine also creates a hum, and this is picked up in the recording.

 

We can reduce the residual noise of the recording device, and restore the original acoustic recording to a clearer sounding digital file.

 

Used less often today, vinyl records produce a unique static that is generated from the mechanics of the record player (i.e.: needle clicks).

 

We can reduce the pops and clicks that come from a vinyl record player and restore the original acoustic recording to a clearer sounding digital file.
