Attenuate Low-Level Noise
Use the Expander block to attenuate low-level noise and visualize the applied dynamic range control gain.
1. Open the Time Scope and Expander blocks.
2. Run the model. To switch between listening to the expanded signal and the original signal, double-click the Manual Switch block.
3. Observe how the applied gain depends on expansion parameters and input signal dyanmics by tuning the Expander block parameters and viewing the results on the Time Scope.
