Turntablism is the art of manipulating sounds and creating new music, sound effects, mixes and other creative sounds and beats, typically by using two or more turntables and a cross fader-equipped DJ mixer. The mixer is plugged into a PA system (for live events) and/or broadcasting equipment (if the DJ is performing on radio, TV or Internet radio) so that a wider audience can hear the turntablist's music. Turntablists atypically manipulate records on a turntable by moving the record with their hand to cue the stylus to exact points on a record, and by touching or moving the platter or record to stop, slow down, speed up or, spin the record backwards, or moving the turntable platter back and forth (the popular rhythmic "scratching" effect which is a key part of hip hop music), all while using a DJ mixer's crossfader control and the mixer's gain and equalization controls to adjust the sound and level of each turntable. Turntablists typically use two or more turntables and headphones to cue up desired start points on different records (Greasley & Prior, 2013). Turntablists, who are often called DJs (or "deejays"), generally prefer direct-drive turntables over belt-driven or other types, because the belt can be stretched or damaged by "scratching" and other turntable manipulation such as slowing down a record, whereas a direct drive turntable can be stopped, slowed down, or spun backwards without damaging the electric motor. The word turntablist is claimed to be originated by Luis "DJ Disk" Quintanilla (Primus, Herbie Hancock, Invisibl Skratch Piklz). After a phone conversation with Disk, it was later popularised in 1995 by DJ Babu to describe the difference between a DJ who simply plays and mixes records and one who performs by physically manipulating the records, stylus, turntables, turntable speed controls and mixer to produce new sounds. The new term coincided with the resurgence of hip-hop DJing in the 1990s. According to most DJ historians, it is has been documented that "DJ Babu" of the "Beat Junkies" / "Dilated Peoples" was the one who originally coined the term "turntablist".

In this notebook we will explore various ways to implement a system
that changes the voice of a speaker. Typical applications for these
techniques, strictly sorted by plausibility, include international spy
missions and prank telephone calls, and devices such as the one
displayed here can be easily bought on the web... or in a novelty shop.
