Capstan is used worldwide by classic record labels along with mastering and restoration studios, broadcasters and archivists, to rescue valuable historical recordings.
Based on Celemony’s patented DNA Direct Note Access technology, the software is capable of detecting wow and flutter from the music itself, regardless of the medium (magnetic tape, vinyl, etc.). Compared to other solutions that rely on reading the bias, Capstan even works in sub-optimal situations, such as when the source tape has been copied several times, or digitized at low sampling rates.
Free to current users, the update to Capstan v 1.2 offers an optional High-Resolution Mode that increases the resolution of the audio analysis by a factor of 4. This allows flutter frequencies up to 14 Hz to be eliminated, at the same time increasing still further the accuracy of the processing.
Pricing and availability. Capstan is available now via the Celemony website. For a small or short-term project, users can rent Capstan for five days for US$/€ 199 for five days. A permanent Capstan license costs US$ 4,458/€ 3,790.
