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 ...
The specification of weighted CCIR-468 quasi-peak noise, and weighted quasi-peak wow and flutter became particularly widely used and attempts were made to find more valid methods for distortion measurement. Measurements based on psychoacoustics, such as the measurement of noise, often use a weighting filter.
A primary design goal was for high fidelity, but having good build quality, control over wow and flutter, and minimized resonance made the equipment particularly suitable for use in nightclubs and other public-address applications. Since its release in 1979, the SL-1200MK2 and its successors were the most common turntables for DJing and scratching.
Pinch wheel or pinch roller is the term for the "rubber" wheel which forms part of the drive mechanism in many forms of tape recorder and player. The magnetic tape is squeezed between the "capstan" (a precision shaft driven at constant speed) and the pinch wheel and so is drawn past whatever combination of record, replay and erase heads the "tape deck" employs.
All of the Hanpin-made turntables seem to have an inordinately high wow and flutter spec, even their own top-of-the-line models, the DJ-5500 and DJ-3560. 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.
The Nakamichi 1000 and 700, made in the mid-1970s, had three heads, a dual capstan drive that reduced wow and flutter, and Dolby-B noise reduction to improve the signal-to-noise ratio. The dual capstan drive ensured superior head-to-tape contact, essentially eliminating reliance on the problematic spring pressure pads built into cassette housings.
Linn presented an important challenge to that by claiming that the source (i.e. the turntable) was the most important part of the system. [1] Ivor Tiefenbrun has talked about how Sondek derives from the term “sound deck” to emphasise the revolutionary concept that the turntable, the “deck”, is responsible for the sound quality. [9]
