Controllable Playback Strange Chant Example
Illustrates the versatility of WaveWarp's controllable file playback feature (see "ControllablePlaybackSimpleExample.dwb"
for a detailed description of the controllable playback functionality). In the present example, the "Controllable Input Audio
File" ( "wavewarp.wav") is fed a Control Signal which alternates between -1 and +1. (This alternating sequence is created
by multiplying the ouput of the Pulse Train Control Generator by 2 (via the Large Control Gain) which produces a sequence
which alternates between 0 and 2. The One Minus Control transforms this to the desired -1 to +1 range.)
Play the DrawingBoard. The effect of the -1 / +1 sequence is to periodically skip the file playback pointer backwards in
time. With the default settings, the net result is a strange gutteral chanting derived from the voice track. (Note that in this
example the Control Running Sum Display monitors the actual file playback pointer location by summing the entire history of
successive step-sizes. This can be a useful aid when trying to decipher just exactly how the achieved effect is obtained !)
Experiment with different settings in the Pulse Train Control Generator and with different audio sources.
See the other "ControllablePlayback...Example" DrawingBoards to appreciate the elaborate effects achievable using
WaveWarp's powerful controllable playback feature.
Note: ALL audio files will appear in both the "Controllable Input Audio Files" category and the "Input Audio Files" category
so it is possible to play ANY file with or without playback control.
