===Other effects===
''Envelope follower'': An envelope follower activates an effect once a designated volume is reached. One effect that uses an envelope follower is the ''[[auto-wah]]'', which produces a "wah" effect depending on how loud or soft the notes are being played.<ref>{{Cite book|last=White, G|first=Louie, G|title=The Audio Dictionary Instruments|url=https://books.google.com/books?id=DulVm8t88QkC&q=flanger+jet+plane|year=2005|publisher=University of Washington Press|page=138|isbn=9780295984988}}</ref><ref>{{Cite book|last=Hopper|first=J|title=The Girl's Guide to Rocking Out|url=https://books.google.com/books?id=RwzQe_h-OjQC|year=2009|publisher=Workman Publishing|page=33|isbn=9780761151418}}</ref>

''[[Guitar amplifier]] modeling'': [[Amplifier modeling]] is a [[Digital data|digital]] effect that replicates the sound of various amplifiers, most often vintage [[tube amplifier]]s and famous brands of speaker cabinets (e.g., the [[Ampeg SVT]] 8x10" bass cabinet). Sophisticated modeling effects can simulate different types of [[speaker cabinet]]s (e.g., the sound of an 8x10" cabinet) and [[miking]] techniques. A rotary speaker simulator mimics the [[doppler]] and [[chorus effect]] sound of a vintage [[Leslie speaker]] system by replicating its volume and pitch modulations, [[overdrive (music)|overdrive]] capacity and [[phase shift]]s.<ref>Bartlett, B; Bartlett, J (2008).

''[[Pitch correction]]/vocal effects'': Pitch correction effects use signal-processing algorithms to re-tune faulty intonation in a vocalist's performance <ref>Brice, Richard (2001). [https://books.google.com/books?id=ufVVgLwkcQwC ''Music Engineering''], Newnes. p. 413.</ref> or create unusual [[vocoder]]-type vocal effects. One of the best known examples of this is [[Autotune]], a software program and effect unit which can be used to both correct pitch (it moves a pitch to the nearest semitone), and add vocal effects. Some stompbox-style vocal pedals contain multiple effects, such as reverb and pitch correction.

''Simulators'': Simulators enable electric guitars to mimic the sound of other instruments such as [[Steel-string guitar|acoustic guitar]], electric bass and [[sitar]]. [[Pick up (music technology)|Pick up]] simulators used on guitars with [[single-coil]] pick ups replicate the sound of guitars with [[humbucker]] pick ups, or vice versa. A de-[[fret]]ter is a bass guitar effect that simulates the sound of a [[fretless bass]]. The effect uses an [[Voltage-controlled filter|envelope-controlled filter]] and [[voltage-controlled amplifier]] to "soften" a note's attack both in volume and [[timbre]].<ref>{{cite web|url=http://www.kellyindustries.com/guitars/boss_gt8.html|title=Boss GT-8 Floor Guitar Effects Processor|access-date=10 September 2010|archive-url=https://web.archive.org/web/20100207042056/http://www.kellyindustries.com/guitars/boss_gt8.html|archive-date=7 February 2010|url-status=dead}}</ref>

''[[Bitcrusher]] filters'': Bitcrushers rely on conversion of the audio signal into a digital format (ADC) and the reduction of sound fidelity by utilising bit (and sometimes sample) rates low enough to cause significant colouration and filtering within the audible frequency range.

''[[Leslie speaker|Rotary speakers]]'' are specially constructed [[amplifier]] and [[loudspeaker]]s used to create special audio effects by rotating the speakers or a sound-directing duct
to introduce the [[Doppler effect]] and other sound reflections. The rotating speaker baffle creates a chorus-type effect. Named after its inventor, [[Donald Leslie]], it is particularly associated with the [[Hammond organ]] but is used with a variety of instruments as well as vocals. The Hammond/Leslie combination has become an element in many genres of music. The Leslie Speaker and the Hammond Organ brands are currently owned by [[Suzuki Musical Instrument Corporation]].

The ''[[Korg Kaoss Pad]]'' is a small [[touchpad]] [[MIDI]] controller, [[sampler (musical instrument)|sampler]], and effects processor for audio and musical instruments, made by [[Korg]]. The Kaoss Pad's touchpad can be used to control its internal effects engine, which can be applied to a line-in signal or to samples recorded from the line-in. Effects types include pitch shifting, [[distortion]], filtering, [[wah-wah (music)|wah-wah]], [[tremolo]], [[flanging]], [[delay (audio effect)|delay]], [[reverberation]], auto-panning, gating, [[phasing]], and [[ring modulation]].
The Kaoss Pad can also be used as a [[MIDI controller]].
