Filter Band Curve
Determines the type of filtering that can be applied to the signal. The following filters are available:
- Low shelf - Boosts or cuts the lower-level frequencies while leaving high frequencies unaffected.
- Peaking - Boosts or cuts a specific frequency region while leaving lower and higher frequencies unaffected. The width of this frequency region can be controlled using the Q property.
- High shelf - Boosts or cuts the higher-level frequencies while leaving low frequencies unaffected.
Default value: High shelf
