Imagine a sound structure with a sound and a container where:
- LPF on Sound = 15
- LPF on Container = 30
In this scenario, the final LPF that will be applied at runtime is 45, which represents a cutoff frequency of 1922 Hz.
Using “real” cutoff frequency values for the low pass filter in Wwise would have looked like this:
- LPF on Sound = 13500 Hz
- LPF on Container = 7000 Hz
In this example, defining the final cutoff frequency at runtime would have been unclear.
The following table associates Wwise LPF values with their corresponding Cutoff Frequencies:
| LPF Value: | Cutoff Frequency (Hz): |
|---|---|

| 1 | 19567 |
