The stutter edit, or stutter effect, is the rhythmic repetition of small fragments of audio, occurring as the common 16th note repetition, but also as 64th notes and beyond, with layers of digital signal processing operations in a rhythmic fashion based on the overall length of the host tempo. The Stutter Edit audio software VST plug-in implements forms of granular synthesis, sample retrigger, and various effects to create a certain audible manipulation of the sound run through it, in which fragments of audio are repeated in rhythmic intervals. The plug-in allows musicians to manipulate audio in real time, slicing audio into small fragments and sequences the pieces into rhythmic effects, recreating techniques that formerly took hours to do in the studio. Electronic musician Brian Transeau (known as BT) is widely recognized for pioneering the stutter edit as a musical technique; he developed, coined the term, and holds multiple patents for the Stutter Edit software plug-in. 
A stutter edit "contains a single segment of audio repeated a number of times, giving a performance a decidedly digital flavor." Stutter edits can go beyond 2,048th notes and can be measured in milliseconds, with layers of digital signal processing operations in a rhythmic fashion, and an individual note potentially containing within it many short fragments of sound. Above a certain point, these repetitions transition from rhythmic to tonal frequencies, making musical notes out of the repeated audio. These extremely short, fast groups of notes are often placed into the spacing of an eighth or sixteenth note in an otherwise "normal" bar, creating rhythmic accenting and patterns that call attention to a particular section. These patterns can be placed at the beginning of a bar, or towards the end for a more syncopated sound. One example is in the second verse of "Drop It Like It's Hot", Snoop Dogg mentions a DJ cut followed by a stutter edit and turntable scratch in reply.

Transeau designed the plug-in to automate the arduous process of breaking audio into micro fragments and using them for new sounds, after experimenting with early versions of the software in his studio and in live performances. Around 2006, Transeau formed the software company Sonik Architects to develop the Stutter Edit plug-in and related tools. In 2010, Sonik Architects was acquired by iZotope, and in January 2011, the Stutter Edit plug-in, based on Transeau's patented technique, was released by iZotope and Transeau. It works by constantly sampling the incoming audio and storing it in a buffer, so that it can be used for repeating short loops or slices, with everything automatically sync'ed to the host tempo. Effects are applied using "Gestures", made up of one or more effects modules or a noise generator, each tied to a single MIDI note. It can be used for live laptop sets or DJing, or in the studio. BreakTweaker, a drum sequencer for beat layering, programming and composition that allows the user to manipulate audio at a micro level, was released by iZotope soon after.
Creation.
Due to the extremely rapid rhythmic bursts, after a certain rhythmic point—i.e. the 128th beat—some stutters begin to sound like a tone rather than a short percussive beat. Traditional stutter edits splice percussive vocals or drum loops because they begin as rhythmic rather than constant tones. These percussive, on-the-beat areas are known as attack transients, and are usually no longer than an eighth note. The splicing of percussive samples results in a more attention-grabbing sound than it would with a single sustained pitch. Stutters also often reduce notes within bars, beginning with 32nd notes, then reducing to 64th and 128th or something similar. There are instances of stutter edits that use logarithmic curves rather than relying on musically locked timings giving the impression of a "speed up" or "slow down".
