Wow and Flutter: This is the waver in a reproduced tone or group of tones that is caused by irregularities in the tape drive speed during recording, duplication, or playing. For example, a change in the angular velocity of the capstan, or dragging of the tape audio cassette shell. The terms "wow and flutter" are often referred to together, flutter being a higher-rate version of wow. All tape players have an amount of wow and flutter with most manufactures indicated their measured tolerance for their specific players when new, so beware of any claim of no wow and flutter in these units when buying. There are many factors that can increase wow and flutter mainly from age and use, this can be dirty or dry moving parts of the unit, including a dirty capstan, polished capstan, capstan bearings, dirty pinch roller/s, dirty head and dirty motor wheel after a belt change. A Worn belt, belt size, quality and pinch roller issue are also the main factors of wow and flutter. All these potential causes are meticulously checked during my refurbishments. Deformations in the cassette compartment can also be a cause, but this is obviously down to which cassette you use and its quality, I always advise a full REW and FF of an older tape before playing, which can help.
