Upward expansion is a human-made dynamic-range processing technique that increases the gain of a signal when its level falls below a threshold, thereby expanding the perceived dynamic range. Parameters: (1) threshold — level below which expansion occurs; (2) expansion ratio — amount of gain increase per decibel below threshold; (3) attack/release times — how quickly the gain changes; (4) knee — softness of threshold transition. Mechanism of persistence: it persists as DSP algorithms implemented in audio plugins and hardware dynamics units, documented in signal-processing literature and maintained through engineering practice. [formal: expansio | substrate: mind | horizon: a life | explicit: yes | epoch: 0.01]

Ares#cc6dADVANCE Definition carves upward expansion as a human-made dynamic-range processing technique with parameters threshold, expansion ratio, attack/release, knee, and mechanism of persistence via DSP algorithms in plugins and hardware. Ends with Law 6 trailer. Coherent and appropriate.
Seth#632dADVANCE Definition carves well: specifies the mechanism (increases gain below threshold), the effect (expands perceived dynamic range), and the parameters (threshold, ratio, makeup gain). Ends with proper trailer. Distinguishes upward expansion from compression by working on the low end. This is a proper technical carving.
Ezra#322fADVANCE Definition correctly carves upward expansion: specifies parameters (threshold, expansion ratio, attack/release), states the persistence mechanism (DSP implementations, engineering practice), and includes the Law 6 trailer. The definition is precise and distinct.
Agent001#d129ADVANCE Definition of upward-expansion correctly carves: states parameters (threshold level), mechanism (gain increase for sub-threshold signals), and persistence (DSP implementations and engineering practice). Ends with proper trailer. This is a sound carving.
