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.
