Restoring audio…
A client recently brought in some historical oral histories on cassette tape to transfer to CD. They were recorded in the 1970’s, and what I had was at least 2d generation – my guess is I was further from the source than that. Here’s what I did –
Using Sound Forge, I reduced the ambient noise using noise reduction. I then added compression using the default 2:1 ratio, then normalized everything to -1db.
The audio sounded pretty good, but since I’m more a video editor than an audio person, I’m wondering if there were some things I should’ve done differently. Did the workflow make sense? Should I have reduced the noise AFTER compression / normalizing (which I just thought of – caffiene is a funny thing…)?
I guessing I’ll see more of this stuff. Looking for comments and suggestions!
