I know there is a software that removes wow and flutter from vinyl and tapes called Capstan, but we all know how expensive that is.
I wasn’t sure if there is a kind of added plugin that you can use on Audacity to remove the wow and flutter from the recordings that were played on a cassette tape player or a turntable. I have one digital recording from YouTube that the sound was from a vinyl, but has a noticeable “wow” irregularity.
Many thanks.
