Audio Frequency Balancer
See how your sound’s energy is spread across sub, bass, mid, treble and air, time-averaged, and how each band sits relative to a neutral balance — so you can spot what’s heavy or thin.
ℹ Relative balance, not calibrated. "Neutral" here means equal energy per octave (a pink-noise reference), which is a rough musical guideline — not a rule. Readings come from an uncalibrated mic and include your room/speakers, so use this to compare bands and spot tendencies, not as an absolute target. Play a representative passage for a few seconds. Nothing is recorded.
Bars show each band’s deviation from your average balance (centre = neutral). Right = heavy, left = light.
How Balance Is Judged
The signal is split into five wide bands — Sub (20–60 Hz), Bass (60–250 Hz), Mid (250 Hz–2 kHz), Treble (2–8 kHz) and Air (8–20 kHz). For each, the analyzer time-averages the energy and divides by the band’s width in octaves, giving energy per octave. That’s the fair way to compare bands of different widths: a spectrum with equal energy per octave — the classic "pink" balance many mixes aim near — reads flat here.
Each band is then compared to the average of all bands, and the difference in dB is its deviation: a band well above the average is "heavy," well below is "light." The bars centre on neutral, extending right for heavy and left for light, with a rating and a gentle EQ hint. Because it’s a relative, uncalibrated mic reading, treat it as a guide to tendencies, not a verdict.
