Description

A very basic sound generator to simulate mains / electric / power line / cycle hum.

Includes controls for switching between a base frequency of 50Hz and 60Hz, setting the strength of the fundamental frequency as well as the 1st, 2nd, and 3rd harmonic, and subtle base frequency fluctuation (-0.75Hz / +0.75Hz).

Also includes an option (enabled by default) for suppressing digital audio clicks/crackles when the various levels are adjusted.

Most controls/parameters are automatable.
