Queryable instance of an [AudioEffectSpectrumAnalyzer].
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 acquired with [method AudioServer.get_bus_effect_instance].
https://godotengine.org/asset-library/asset/2762
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].
Use the average value across the frequency range as magnitude.
Use the maximum value of the frequency range as magnitude.
