3-band Equalizer

Shapes audio with three fully parametric bands — each with its own centre frequency, gain, and Q (bandwidth) — plus an overall input-gain control. Unlike the fixed-frequency 10-band Equalizer, every band here can be tuned to any frequency between 20 Hz and 20 kHz, with an adjustable bandwidth, making it a flexible tool for surgical corrections (notching out resonance, taming sibilance) as well as broad tonal shaping. Includes a clip indicator that flags signal overload and a one-click reset.

3-band Equalizer - Settings

Input

Input — overall level applied before the band gains.

Property	Description
`Input Gain (dB)`	Master input level applied before the band processing, in decibels. [min=-36, max=36, default=0]. 0 leaves the level unchanged. Negative values reduce the input level; positive values boost it (watch out for `SignalOverLoad`).

EQ 1

EQ 1 — first parametric band (frequency, gain, Q).

Property	Description
`Frequency (Hz)`	Centre frequency of band 1, in Hz. [min=20, max=20000, default=500]. The frequency this band boosts or cuts. Pick a low value to target bass, mid for body and presence, high for sibilance and air.
`Gain (dB)`	Gain applied at band 1's centre frequency, in decibels. [min=-36, max=36, default=0]. 0 leaves the band unchanged; positive values boost it, negative values cut it.
`Q`	Bandwidth (Q) of band 1. [min=0.1, max=10, default=1]. Controls how wide the band is around its centre frequency. Low values give a broad, musical curve; high values give a narrow, surgical notch — useful for cutting a specific resonance or piece of unwanted noise without affecting nearby frequencies.

EQ 2

EQ 2 — second parametric band (frequency, gain, Q).

Property	Description
`Frequency (Hz)`	Centre frequency of band 2, in Hz. [min=20, max=20000, default=3000].
`Gain (dB)`	Gain applied at band 2's centre frequency, in decibels. [min=-36, max=36, default=0].
`Q`	Bandwidth (Q) of band 2. [min=0.1, max=10, default=1].

EQ 3

EQ 3 — third parametric band (frequency, gain, Q).

Property	Description
`Frequency (Hz)`	Centre frequency of band 3, in Hz. [min=20, max=20000, default=8000].
`Gain (dB)`	Gain applied at band 3's centre frequency, in decibels. [min=-36, max=36, default=0].
`Q`	Bandwidth (Q) of band 3. [min=0.1, max=10, default=1].

Warnings

Warnings — clip indicators that flag when the signal is too loud.

Property	Description
`Signal overload`	True when the equalizer's output signal has clipped (read-only). Lights up when the combined boost from input gain and band gains pushes the signal above full scale. Auto-resets after 2 seconds. Reduce `InputGain` or trim the boosted bands if this trips.
`Peak Overload (dB)`	Highest level reached during the most recent overload, in decibels (read-only). Updated whenever `SignalOverLoad` trips, and auto-resets after 2 seconds.

Actions

Actions — one-click commands.

Property	Description
`Reset`	Reset all settings to their defaults. Restores `InputGain` to 0, and each band's frequency, gain, and Q to its starting value (500 Hz / 3 kHz / 8 kHz at 0 dB and Q=1).
