方法

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) const 🔗

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.
