Anthemic, weight-focused section

Slower, half-time section emphasising sonic weight via low palm-muted chugs, kick drum, and floor tom; more rhythmic space and low-frequency emphasis.

🔊 Acoustic Hardness

4.51 High

Key Predictors

Spectral Complexity 28.88

Spectral Contrast (1.6–3.2 kHz) 15.54 dB

Dissonance 0.482

HPCP Entropy 2.26

High spectral complexity combined with dense upper-midrange content creates a textural hardness strongly associated with heaviness perception.

💥 Temporal Punch

-24.31 dB Moderate

PM95 (Peak-to-Loudness) -24.31 dB

PLR (Dynamic Range) 10.35 dB Moderate

Moderate PM95 values suggest some transient clarity, but in spectrally saturated mixes, hardness (β ≈ .688) remains the dominant predictor of heaviness.

Key Finding: While listeners perceive punch as salient, acoustic PM95 fails to track subjective punch in dense mixes. The production trade-off favors spectral saturation (hardness) over transient preservation (punch).

Subjective Punch 0.15

Brightness -0.01

Roughness -0.02

Clarity 0.04

Key Insight: Perceived heaviness and subjective punch show strong correlation (listeners associate them), but acoustic PM95 fails to track subjective punch in dense mixes. This disconnect reveals that heaviness perception in metal is driven primarily by spectral-textural hardness rather than transient impact.
