Sub-bass
Deep rumble, extension, and physical scale.
Sound Lab · Tonal balance
EQ Playground turns six broad frequency regions into a visual, hands-on learning tool. Adjust the curve, read what each change is likely to emphasize, and get ready for volume-matched before-and-after listening in the full release.
Shape the tonal balance
The sliders update the graph and explanation in real time. The final release adds controlled audio playback, band soloing, bypass, and volume-matched A/B comparison.
Relative emphasis · ±6 dB learning range
Rumble, extension, and physical scale. Too much can overpower the rest of the mix.
Conceptual tonal visualization only. Perceived effect depends on the original recording, playback chain, fit, listening level, and individual hearing.
Six regions · One complete sound
The content avoids one-to-one myths such as "this slider controls vocals." Each region affects overlapping fundamentals, harmonics, attacks, and spatial cues.
Deep rumble, extension, and physical scale.
Punch, warmth, and rhythmic weight.
Body in voices and instruments.
Presence, clarity, and articulation.
Attack, edge definition, and detail.
Openness, shimmer, and upper harmonics.
What audio adds
The final audio layer is carefully level matched and makes clear that browser playback is not a calibrated measurement or a substitute for safe listening habits.
Switch between the original and adjusted version without a volume jump.
Briefly isolate the band as an educational cue, then return to full-range music.
Short music and sound examples chosen to reveal each region clearly.
Keep personal presets, compare them, and understand why each one was created.
