<description>
|
|
The runtime part of an [AudioEffectSpectrumAnalyzer], which can be used to query the magnitude of a frequency range on its host bus.
|
|
An instance of this class can be obtained with [method AudioServer.get_bus_effect_instance].

Returns the magnitude of the frequencies from [param from_hz] to [param to_hz] in linear energy as a Vector2. The [code]x[/code] component of the return value represents the left stereo channel, and [code]y[/code] represents the right channel.
|
|
[param mode] determines how the frequency range will be processed. See [enum MagnitudeMode].
