Celemony Capstan Restoration Software

Capstan by Celemony is recording restoration software that digitally corrects wow and flutter in analog recording mediums such as tape, vinyl, cassettes, wax, and shellac. Wow and flutter are caused by mechanical inaccuracies in the medium or player that lead to variable and inconsistent playback speeds. The software uses elements of Celemony's Melodyne DNA algorithm to analyze the musical content and detect pitch anomalies within polyphonic material. It then corrects the anomalies by inverting the velocity curve in problematic sections to remove the effects of wow and flutter. You can operate the software in automatic mode or draw in the correct velocity curves manually to correct the pitch.
