AnequalizerEffect class final

Configuration for the anequalizer audio effect.

High-order parametric multiband equalizer for each channel.

It accepts the following parameters:

Parameters:

colors: set channels curves colors (range 0..0, default "red|green|blue|yellow|orange|lime|pink|magenta|brown")
curves: draw frequency response curves (range 0..1, default 0)
fscale: set frequency scale (range 0..1, default 1)
mgain: set max gain (range -900..900, default 60)
params: This option string is in format: "cchn f=cf w=w g=g t=f | ..." Each equalizer band is separated by '|'. (range 0..0, default "")
size: set video size (range 0..0, default "hd720")

bands → List<AnequalizerBand>: Available on AnequalizerEffect, provided by the AnequalizerBandsX extension
Decoded list of bands in declaration order. Reads the underlying params string; the per-channel repeats withBands emits are collapsed back to one entry per logical band.
no setter

curves → bool: draw frequency response curves
final
enabled → bool: Whether this effect is applied. false keeps it in the list, with its settings, without inserting it in the chain.

copyWith({bool? enabled, String? colors, bool? curves, AnequalizerFscale? fscale, double? mgain, String? params, String? size}) → AnequalizerEffect: Returns a copy of this AnequalizerEffect with the given fields replaced.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.

toFilterString() → String: Returns the audio chain entry for this effect. Only non-default parameters are emitted.

toString() → String: A string representation of this object.
override
withBands(List<AnequalizerBand> bands, {int channels = _anequalizerDefaultChannels}) → AnequalizerEffect: Available on AnequalizerEffect, provided by the AnequalizerBandsX extension
Returns a copy whose params reflects bands. Each band is emitted for channels 0 to channels - 1 of the filter's input.
