Celemony Capstan Restoration Software, Electronic Download

For over a hundred years, music has been recorded on mechanical mediums. And for over a hundred years, there has been a problem with this: wow and flutter. Who isn't familiar with the wobbling and warbling, the droning and dragging? Mechanical degradation caused by defective devices or sticking tapes, by ageing or defective storage. In the past, it was usually impossible to get rid of wow and flutter.

Countless recordings of renowned orchestras, big bands and rock groups are currently slumbering deep in archives. Yet they are unusable, simply due to wow and flutter. The tapes worthless, the recordings lost to posterity. Until now. For, in Capstan, there is now for the first time a program capable of removing wow and flutter from recorded music. Whether on tape, compact cassette, wax, shellac or vinyl.

Musical intelligence
The Capstan algorithm is capable of recognizing not only the smallest amounts of wow and flutter but also continuous speed variations within the musical material. It allows detailed editing that extends even to letting you draw in the curve by hand. Capstan's detection of notes and their deviations is based on the patented DNA Direct Note Access technology made famous by the program Melodyne, which is used in major studios the world over for the editing of pitch and timing.

What the experts say
Capstan has been used in many renowned projects, restoration- and mastering studios all over the world - with outstanding results.

Precise control
How far Capstan reaches into your music to correct wow and flutter is something you can determine precisely. The correction is effected through pure airspeed and therefore introduces no artifacts.

Capstan detects wow and flutter from the music itself
The medium is irrelevant. In this, Capstan is clearly superior to solutions such as bias tracking: Capstan still works, for example, when the tape has already been copied several times.

Capstan - demo version
An end to wow and flutter. With this demo version, you can test the full range of functions of Capstan but you can neither save nor export the results. And although the demo version analyses the entire audio file, playback stops after seven seconds. To try it out, locate the critical passages in your material and start playback just before them. To get you started, they have prepared a small tutorial including audio illustrations. You will find the tutorial in the user manual. The audio files are installed by the demo installation program. Capstan is for the time being only available in English.
