Diminish Plosives from Speech

This model minimizes the plosives of a speech signal by applying highpass filtering and low-band compression.

Plosives are consonant sounds resulting from a sudden release of airflow. They are most pronounced in p, d, and g words. Plosives can be emphasized by the recording process and are often displeasurable to hear.

To explore this model, tune the highpass filter cutoff and the parameters on the Compressor and Crossover Filter blocks. Switch between listening to the original and processed signals by double-clicking the Manual Switch block.
