Exciter is the tenth studio album by the English electronic music band Depeche Mode, released in the United Kingdom on 14 May 2001 by Mute Records and in the United States on 15 May by Reprise Records. The album was produced by Mark Bell of Björk and LFO fame. The album also launched the Exciter Tour, one of the band's most successful tours.

Exciter debuted at number nine on the UK Albums Chart and at number eight on the Billboard 200, selling 115,000 copies in its first week in the US. It is the only Depeche Mode album to debut higher in the US than in the UK. As of April 2006, Exciter had sold more than 426,000 copies in the US, and was certified Gold by the Recording Industry Association of America (RIAA). The album was also certified Gold in Canada for shipments of 50,000 units. The remastered album was released on "deluxe" vinyl 30 March 2007 in Germany and 1 October 2007 internationally.

The plant that appears on the cover is the agave attenuata, a species of agave sometimes known as the "lion's tail", "swan's neck," or "foxtail" for its development of a curved stem, unusual among agaves. It is used to produce tequila.

Exciter is a Canadian speed metal band from Ottawa, Ontario. They are widely considered to be one of the first speed metal bands and a seminal influence of the thrash metal genre. Exciter have sold nearly 300,000 units in the USA and a total sales close to 500,000 units worldwide. Despite many changes in personnel, the band has managed to keep a small but dedicated following for over 30 years.

An exciter (also called a harmonic exciter or aural exciter) is an audio signal processing technique used to enhance a signal by dynamic equalization, phase manipulation, harmonic synthesis of (usually) high frequency signals, and through the addition of subtle harmonic distortion. Dynamic equalization involves variation of the equalizer characteristics in the time domain as a function of the input. Due to the varying nature, noise is reduced compared to static equalizers. Harmonic synthesis involves the creation of higher order harmonics from the fundamental frequency signals present in the recording. As noise is usually more prevalent at higher frequencies, the harmonics are derived from a purer frequency band resulting in clearer highs. Exciters are also used to synthesize harmonics of low frequency signals to simulate deep bass in smaller speakers.

Originally made in valve ( tube) based equipment, they are now implemented as part of a digital signal processor, often trying to emulate analogue Exciters. Exciters are mostly found as plug-ins for sound editing software and in sound enhancement processors.

Exciter is the fifth studio album by the Canadian speed metal band Exciter, released through the Canadian label Maze Music in 1988. The album was re-released in 1995 Magnetic Air Records and again by Megaforce Records in 2005 with the title O.T.T., which stands for Over the Top. This is the first album as a quartet, with new frontman Rob Malnati replacing Dan Beehler as lead vocalist of the band.

"Exciter" is a song by British heavy metal band Judas Priest, from their 1978 album Stained Class. It is the opening track and is an early example of speed metal.
