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 changes in frequency are caused by irregular tape motion during recording or playback. For example, a change in the angular velocity of the capstan, or dragging of the tape within a reel or audio cassette shell. The terms "wow and flutter" are often referred to together, flutter being a higher-rate version of wow.
In music, a loop is a repeating section of sound material. Short sections can be repeated to create ostinato patterns. Longer sections can also be repeated: for example, a player might loop what they play on an entire verse of a song in order to then play along with it, accompanying themselves.
It was the only source of quality sound used for the distribution of Western music as well as underground local artists. [citation needed] There has recently been a revival of reel-to-reel, with quite a few companies restoring vintage units and some manufacturing new tape. In 2018, the first new reel-to-reel tape player in over 20 years was ...
The frequency range often specified for audio components is between 20 Hz to 20 kHz, which broadly reflects the human hearing range. Well-designed solid-state amplifiers and CD players may have a frequency response that varies by only 0.2 dB between 20 Hz to 20 kHz. [4]
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 ...
Delay is an audio signal processing technique that records an input signal to a storage medium and then plays it back after a period of time. When the delayed playback is mixed with the live audio, it creates an echo-like effect, whereby the original audio is heard followed by the delayed audio. The delayed signal may be played back multiple ...
The speed of each motor is governed by a phase-locked loop; both loops are synchronized with a common crystal oscillator. According to Studer, each capstan was machined to a precision of 1 μm (0.001 mm or 0.000039 inch), to ensure very low wow and flutter.
