Dub techno treats the mixing desk as a creative instrument, a technique borrowed directly from Jamaican dub
Each additional bit of word length adds approximately 6 dB of dynamic range
EQ boosts on multimiked tracks change comb-filtering relationships unpredictably; cuts are safer
EQ feathering applies small amounts of equalization at adjacent frequencies instead of a large boost at one frequency
EQ's crucial mix job is reducing frequency masking, not beautifying soloed sounds
Every great mix requires six elements: balance, frequency range, panorama, dimension, dynamics, and interest
Expansion and gating reduce unwanted low-level signals by reversing dynamic range compression
Experienced mixers hear the finished product in their heads before touching a fader
Fader dB scales are logarithmic: small physical moves at the bottom of the fader travel cause large level changes
Fast attack catches and suppresses transients; slow attack lets them pass through before compression engages
Feeding a frequency-shaped copy into a compressor's detector makes it react only to those frequencies
Floating-point DAW mixing gives effectively unlimited headroom, so channel overloads don't distort

Gated reverb with increased pre-delay gives a drum hit a large-then-truncated ambience
Give each element its own ambient environment so reverbs and delays do not clash

Hypercompression flat-lines the waveform to chase loudness, destroying dynamics irreversibly
In mastering, the compressor and limiter are two separate units with distinct roles
Inaudible subsonic energy from rumble, drafts, samples and DC wastes mix headroom

Peak normalization matches peaks but not perceived loudness, which drove the loudness war
Professional mastering adds value beyond loudness: tonal balance, song sequencing, and a fresh reference set of ears
Purely tonal EQ (for subjective appeal rather than balance) can freely use boosts and analogue character
Reverb and delay create front-to-back depth — the mix's third dimension beyond frequency and stereo
Reverb and delay effects can be widened using MS or other stereo-enhancement techniques on the return channel
Reverb bundles several enhancements at once, so design a separate patch for each subset you need
Reverb can counteract masking by extending sustain or widening a masked sound
Reverb predelay sets a gap between dry attack and reverb onset that controls clarity and perceived distance
Room modes are standing waves between parallel boundaries at frequencies determined by room dimensions
Sample rate determines digital audio bandwidth: the system can represent frequencies up to half the sample rate
Sample-peak meters miss inter-sample peaks, which can exceed 0 dBFS by 3 dB and require an oversampling True-Peak meter
Sending several parts to one reverb return places them in a single shared acoustic space
Shelving EQ affects all frequencies above (or below) a hinge point; peaking EQ affects a band around a center frequency
Sidechain keying drives a compressor's level detection from a different signal than the one being compressed
Sidechain-pump has two roles: functional masking-avoidance between kick and bass, and aesthetic pump as a genre signature
Sidechaining a sustained sound to a muted kick creates rhythmic pumping without an audible drum
Six principles govern effective reverb and delay use: space, size, distance, timing, conspicuousness, and smoothness
Size reverb is deliberately audible and implies an instrument was recorded in a larger space than it actually was
Soft clipping at a limiter's ceiling adds subtle harmonic grit instead of hard gain reduction

The RIAA equalization curve boosts highs and cuts lows during vinyl cutting, with the inverse applied on playback
The threshold is the level above which a compressor starts reducing gain
Threshold and makeup gain are the two essential compressor controls; all others refine the action
Valve (tube) amplifiers produce a warmer, rounder bass that deepens as they heat up during play
Variable pitch expands groove spacing before loud low-frequency passages and contracts it during quiet sections to maximize playing time
Vertically separated drivers comb-filter around the crossover, right where hearing is most sensitive
Vinyl mastering must account for the cartridge compliance of the intended playback system
VU meters track average level (close to perceived loudness); peak meters track instantaneous peaks, 10–25 dB higher
