Description

Source Sound

Motor boat sounds.

Target Sound

Jeep sounds.

Synthesis Constraints

Influence is starts at '1', then dips to 0 (i.e. unconstrained synthesis), then goes back to  '1'.

Comments

This example illustrates the ability to vary across time the influence of the target sound.

Same as previous example except that we vary the influence of the target/guiding sound over time. The result is that the synthesis initially closely follows the target sound, reverts to unconstrained synthesis, then follows once again the target sound.

New Sound

 

(top) Shows the old segmented sound along each constraints source segments. (middle) Shows the synthesized sound. (bottom) Shows Constraint targets along with how the origin of the grains in these targets regions.

(top left) Shows the original probabilities for every grain at each instant of the synthesis over time. (top right) Shows how the original propabilities where rescaled according to the weights at that current in the synthesis. (bottom left) Illustrates the difference between the two initial and new probabilities. (bottom right) Shows the target weights for each constraints. The surface represents the final calculated weights for each grain. The final weights assigned to each grain depends on wether it satisfies or not the current constraint targets. A weight of zero means that it-s original probability is left unchanged.
