I am now concerned with repairing a recording I got from an old audiotape, which naturally poses many artifacts to fix.
The artifact that occurs relatively often is a kind of "shaky" audio, which can be clearly seen on the spectral frequency display:
Can Adobe Audition help me to fix this?
No it can't, I'm afraid. This is a specialist job, and the software that does it is fantastically expensive. One of the main players is Celemony's Capstan - and you can rent five days of use of it for a measly $199. This is software that makes Adobe's rental deal seem like an absolute bargain!
Just in case you were wondering, the full unlimited version of Capstan costs... wait for it... $4458.00
