late 14c., "terror," from Old French tremor "fear, terror, quaking" (13c.), from Latin tremorem (nominative tremor) "a trembling, terror," from tremere (see tremble (v.)). Sense of "an involuntary shaking" first recorded 1610s and probably represents a re-introduction from Latin.

n. 1 A shake, quiver, or vibration. 2 An earthquake. vb. To shake or quiver excessively and rapidly or involuntarily; to tremble.

1. n. an involuntary vibration (as if from illness or fear) [syn: shudder]

2. a small earthquake [syn: earth tremor, microseism]

3. shaking or trembling (usually resulting from weakness or stress or disease)

4. v. shake with seismic vibrations; "The earth was quaking" [syn: quake]

A tremor is an involuntary, somewhat rhythmic, muscle contraction and relaxation involving oscillations or twitching movements of one or more body parts. It is the most common of all involuntary movements and can affect the hands, arms, eyes, face, head, vocal folds, trunk, and legs. Most tremors occur in the hands. In some people, a tremor is a symptom of another neurological disorder. A very common tremor is the teeth chattering, usually induced by cold temperatures or by fear.

Tremor may refer to:

• Tremor, a rhythmic, oscillating shaking movement of the hand, or other parts of the body
• Tremor, or earthquake, the shaking or trembling of the earth
• Tremor (software), the integer-only Vorbis audio decoding library

Tremor is a fictional character from the comic book series, Spawn. He is a former Mafia enforcer and associate of Antonio "Tony Twist" Twistelli, the Don of New York, and is now a vigilante seeking revenge on The Family.

"Tremor" is a song by Belgian DJ duo Dimitri Vegas & Like Mike and Dutch DJ and record producer Martin Garrix.

Tremor by the Xiph.Org Foundation is a fixed-point version of the Vorbis decoder for those platforms without floating point operations.

It is a software library that decodes the Vorbis audio format. It is free software released under the New BSD license. Tremor uses fixed-point and movable-point arithmetic numeric representations in its implementation so that it can be used by small embedded devices, which typically do not have floating-point processors. Thus, Tremor enables small embedded devices to play audio files stored in the Vorbis format. Tremor was originally developed by Xiph.Org as a part of a contract for the Iomega HipZip, but was since opened up to encourage wider use of the Vorbis format. Almost all hardware devices that can play Vorbis, and many software implementations on embedded devices (such as mobile phones) use Tremor or some descendant.

Xiph.Org has expressed interest in modifying Tremor into a floating-point version, which would replace the current floating-point reference decoder, after the release of libogg2.
