Figure 5.1: Thump Signal Flow
The block diagram above illustrates the overall structure of the processing system provided by Thump. The
diagram does not indicate the various metering blocks.
Now lets examine the various processing blocks indicated in the diagram.
Amplitude Followers
Thump's Amplitude Followers convert the audio input into control signals for the oscillators. The Envelope
Amplitude Follower extracts an envelope that is used to control the amplitude of the output of the oscillator.
The Pitch Amplitude Follower extracts an envelope that is used to control the pitch of the oscillators.
