Audio Restoration

Recently I completed an audio restoration project on an old 33rpm vinyl recording. Oddly enough it had the same footprint as a 78 but was in fact recorded at 33rpm. This disc dated back to the 1950’s and was recorded in mono directly to vinyl, all in one take. Needless to say in was in poor condition and required some careful considerations in removing noise without introducing a slew of additional artifacts. Here are some samples:

These examples use a DAW plugin from iZotope called Vinyl. I actually think the plugin is used to add noise as an effect but some of the parameters are very useful for removing mechanical wear as well. The next examples show the more common click and pop artifacts you hear when restoring vinyl recordings. Here I used a plugin from Waves called X-Click with great results.

I highly recommend these plugins for their effectiveness while remaining transparent.
