Scrape Flutter
High-frequency flutter, above 100 Hz, can sometimes result from tape vibrating as it passes over a head, as a result of rapidly interacting stretching in the tape and stiction at the head. This is termed 'scrape flutter'. It adds a roughness to the sound that is not typical of wow & flutter, and damping devices or heavy rollers sometimes employed on professional tape machines to prevent it. Scrape flutter measurement requires special techniques, often using a 10 kHz tone.

Famous quotes containing the words scrape and/or flutter:

must scrape his knees, and bring
the grip of his hands into play. The cut stone
consoles his groping feet. Wings brush past him.
The poem ascends.”

“Scarlet, and blue, and snowy white,
The guidon flags flutter gaily in the wind.”
