Antiflutter is a VST plugin to reduce flutter (pitch variations) from analog tapes caused by excentricity or dirt on the capstan axle (or to correct for any periodic pitch variations in audio material).

What makes this plugin different from your normal "vibrato" plugin is:

• Very precise frequency control (down to a ten-thousandth of a Hz).
• Stereo processing.
• Phase of the cyclical pitch change is precisely locked to the VST time position so the correction is reproducible.
