The Dictabelt,[1] in early years and much less commonly also called a Memobelt, is an analog audio recording medium commercially introduced by the American Dictaphone company in 1947.

[2] The belt is loaded onto a pair of metal cylinders, put under tension, then rotated like a tank tread.

[5] Dictabelts were more convenient and provide better audio quality than the reusable wax cylinders they replaced.

If a belt is stored sharply folded for a long time, it will become permanently creased and unplayable without special treatment.

These recordings were reviewed by the United States House Select Committee on Assassinations (HSCA).
