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 AudioServer.get_bus_effect_instance().
MAGNITUDE_AVERAGE = 0
Use the average value across the frequency range as magnitude.
MAGNITUDE_MAX = 1
Use the maximum value of the frequency range as magnitude.
Returns the magnitude of the frequencies from from_hz
to to_hz
in linear energy as a Vector2. The x
component of the return value represents the left stereo channel, and y
represents the right channel.
mode
determines how the frequency range will be processed. See MagnitudeMode.
