AudioEffectSpectrumAnalyzerInstance
继承： AudioEffectInstance < RefCounted < Object
Queryable instance of an AudioEffectSpectrumAnalyzer.
描述
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 AudioServer.get_bus_effect_instance.
方法
Vector2 | get_magnitude_for_frequency_range ( from_hz: float, to_hz: float, mode: MagnitudeMode = 1 ) const1 |
枚举
enum MagnitudeMode:
MagnitudeMode MAGNITUDE_AVERAGE = 0
Use the average value across the frequency range as magnitude.
MagnitudeMode MAGNITUDE_MAX = 1
Use the maximum value of the frequency range as magnitude.
方法说明
Vector2 get_magnitude_for_frequency_range ( from_hz: float, to_hz: float, mode: MagnitudeMode = 1 ) const1
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.
