An ADSR envelope shapes a parameter over four gate-driven stages: attack, decay, sustain, release

An ADSR envelope shapes amplitude or timbre over four stages: Attack, Decay, Sustain, Release

An AM radio tuned to a dead band becomes an electromagnetic field detector for motors, computers, and household appliances

An analog signal is literally an electrical analogy of the physical quantity it represents

An Ardour session is a folder containing all project data: audio, MIDI, routing, and snapshots

An attenuator is a VCA without voltage control — a fixed-gain module used to scale CV and audio signals

An attenuverter scales a signal from full positive through zero to full inverted with one knob

An electronic instrument's interface can be analysed as a layered model from sound through control and layout to concept and time

An envelope generator outputs a time-varying control signal that shapes another module's parameter over each note

An exponential fade-out curve is often smoother and more realistic than a linear fade

An interval is a musical distance measured in semitones, and it repeats every octave (12 semitones)

An isochronous rhythm places its onsets at perfectly regular intervals — the trivial case where k divides n

An LFO is a sub-audio oscillator used as a control source to cyclically modulate another module's parameter

An open hi-hat on every off beat anchors the eighth-note pulse in Detroit techno

An open-hardware module publishes its design files under CC-BY-SA so builders can make, modify, and share it

An OSC message has two parts: an address pattern (the parameter name) and one or more typed arguments (the values)

Analog/digital and continuous/discrete are two independent axes — not two names for the same thing

Angle brackets in mini-notation advance one element per cycle, not per step

Angle brackets in mini-notation pick one value per cycle, rotating through the list

Any complex waveform can be built by summing sine waves — this is the basis of additive synthesis

Any live cinema performance can be analysed through five tool-independent essential elements

Art-Net transports DMX512 and RDM lighting data over an Ethernet network

Artists labelled IDM widely rejected the term as elitist and PR-driven

Artists may maintain separate aliases for stylistically distinct projects within related genres

As an LFO crosses into the audio range it stops being perceptible parameter movement and starts creating sidebands

Asterisk in mini-notation speeds up a step, fitting n repetitions into its allotted time slot

At high SPL, sub-bass is experienced as full-body resonance, felt before it is heard

Audacity Macros chain effects into a reusable sequence for batch-processing multiple audio files

Audacity's Spectrogram view shows frequency content over time, enabling spectral selection and editing

Audio connections longer than 8 inches require shielded cable to prevent electromagnetic hum pickup

Audio-only pirate radio made vocal distinctiveness, not image, the currency of an MC's reputation

Audio-reactive synthesis generates visuals from sound data rather than triggering pre-recorded clips

Balearic trance emerged at Ibiza's Café del Mar blending Mediterranean instruments, ambient pads, and sunset aesthetics

Baltimore club emerged in the late 1980s by fusing house, UK rave, Miami bass and hip-house

Baltimore club's tempo rose from 125-128 BPM to 130+ and keeps accelerating

Banana jack colors on the Buchla 200e encode signal direction and type at a glance

bank() repoints a pattern's drum abbreviations at a named drum-machine sample set

Battery-only operation is the primary safety rule for hardware-hacking live circuits

Because genre lines blurred, authentic progressive house often 'masquerades' as techno, tech house, or deep house

Beginners should choose a Eurorack case with built-in power to avoid the complexity of separate PSU installation

Belgium's Bonzai Records defined a harder, driving trance aesthetic parallel to Germany's melodic approach

Berghain in Berlin has been described as 'possibly the current world capital of techno'

Big Apple Records in Croydon was the physical hub where dubstep's founding producers learned from each other before any clubs existed

Big beat crossed from clubs to mainstream via The Prodigy and Fatboy Slim's chart success in 1995–1999

Big beat declined from 2001 as its leading acts shifted to house/techno/trance characteristics and the novelty faded

Big beat emerged from early 1990s London dance music hybridisation when labels released breakbeat music alongside house

Big beat inherited its breakbeat and sampling approach from British turntablism pioneers like Coldcut

Big beat layers heavy distorted breakbeats over four-on-the-floor kicks and acid lines at mid-tempo for mainstream crossover

Big beat spread into mainstream culture through film and video-game soundtracks, not only record sales

Boom bap places a hard acoustic kick on downbeats and a snappy snare on upbeats with an in-your-face mix

Breakbeat hardcore diverged into jungle and drum and bass by accelerating tempo and chopping the break

Breakcore chops breakbeats at extreme tempos over irregular meters, aggression tempered by emotional depth

Breakcore has no melodic identity — its rhythmic density is the defining feature, not harmony or melody

Breakcore is a high-tempo electronic genre defined by hyper-complex breakbeat manipulation and wide-spectrum sampling
