Measurement of wow and flutter is carried out on audio tape machines, cassette recorders and players, and other analog recording and reproduction devices with rotary components (e.g. movie projectors, turntables (vinyl recording), etc.) This measurement quantifies the amount of 'frequency wobble' (caused by speed fluctuations) present in ...
The terms "wow and flutter" are often referred to together, flutter being a higher-rate version of wow. Scrape flutter—a high-frequency flutter of above 1000 Hz—can sometimes occur from the tape vibrating as it passes over a head, as a result of rapidly interacting stretch in the tape and stiction at the head. It adds a roughness to the ...
Wow and flutter are a change in frequency of an analog device and are the result of mechanical imperfections. Wow is a form of flutter that occurs at a slower rate. Wow and flutter are most noticeable on signals which contain pure tones. For LP records, the quality of the turntable will have a large effect on the level of wow and flutter.
"Wow" is slow speed (a few Hz) variation, caused by longer-term drift of the drive motor speed, whereas "flutter" is faster speed (a few tens of Hz) variations, usually caused by mechanical defects such as out-of-roundness of the capstan of a tape transport mechanism. The measurement is given in % and a lower number is better.
The Nakamichi Dragon is an audio cassette deck that was introduced by Nakamichi in 1982 and marketed until 1994. The Dragon was the first Nakamichi model with bidirectional [a] replay capability and the world's first production tape recorder with an automatic azimuth correction system; this feature, which was invented by Philips engineers and improved by Niro Nakamichi, continuously adjusts ...
The only exception to this for Hanpin-made turntables seems to be the ReLoop RP-7000 and RP-8000 which claim a wow and flutter spec of 0.01% wrms. Possibly the ReLoop turntables have a greatly improved platter design to reduce axial run-out of the platter but no mention of that is made in the product literature.
This effect is called a wow-and-flutter, and a modern, tachometer-regulated cassette deck has a wow-and-flutter of 0.07%. Tachometers are acceptable for high-fidelity sound playback, but not for recording in synchronization with a movie camera. For such purposes, special recorders that record pilottone must be used.
