Sonitus:fx — fx:wahwah

A wahwah guitar effect emulator, modeled after real-life wahwah stomp boxes.

fx:wahwah lets you define the filter settings for the low and high point in the wah envelope. It then offers three modes of morphing between these two settings to create the wahwah sound. Manual wah mode lets you control the wahwah action directly using a mouse, auto wah mode does it automatically by using a specified BPM tempo, while triggered wah mode uses a threshold level to trigger the wahwah effect and attack and release time parameters for the envlope.
