The Brickwall Limiter ensures that audio signals (even short ones) always stay below a set limit without creating audible artifacts.
- Threshold
-
Sets the lowest input level in dB where reduction kicks in. If the input signal exceeds the threshold, the gain is reduced.
- Release
-
Specifies the duration the reduction lasts after the input signal falls below the threshold.
- Gain Reduction:
-
If this level indicates constant limiting, try raising the threshold or lowering the overall gain level of the input signal, as the Brickwall Limiter is primarily designed for cutting occasional signal peaks.
Note
By default, a Brickwall Limiter is placed at the end of the audio signal chain, i.e. as the last master insert. To access it, open the mixer and choose the 
symbol on the Stereo Out channel.
