What it does
Controllable Playback Arbitrary Speed Example 2
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" ( "drums.wav") is fed a Control Signal from the Controllable Playback Speed Controller. The Controllable Playback Speed Controller, in turn, is fed a time-varying signal from the Combo Control Generator (the Large Control Gain merely scales the signal to within the desired range). The net result is that the playback rate of the audio file is smoothly modulated according to the signal from the Combo Control Generator.
Play the DrawingBoard and note the "flanging-like" effect (this is not a coincidence since the classic "flanging" effects was invented by varying the playback rate of a reel-to-reel tape player by hand !).
Try adjusting the settings of the Combo Control Generator to experiment with different playback rate profiles. Note that you have complete flexibility in determining the playback rate profiles. You can even design them yourself off-line, then read them in (as wavetables) using the "Read wavetable from file" feature of the Combo Control Generator. You can also read them as a simple lists of values stored as ASCII files (using the "ASCII Input Files" category).
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.
