Audio Frequency Balancer
This audio frequency balancer shows your spectral balance 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-noise reference many mixes aim near — reads flat here. To see the full octave-by-octave picture at higher resolution, pair these results with the audio spectrum analyzer.
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 — making this a quick EQ check for tonal balance and frequency balance without needing a full spectrum plot. Because it’s a relative, uncalibrated mic reading, treat it as a guide to tonal tendencies, not a verdict. Heavy sub or bass can signal a bass-heavy mix or a room with low-frequency buildup; a light treble or air band may point to excessive high-frequency roll-off from your room, speakers, or recording chain. During mixing, this balancer gives a fast read on whether a track leans too dark or too bright before you reach for a DAW equalizer. If the overall level matters alongside tonal balance, the LUFS meter gives a complementary loudness reading.
