Augmentation and Diminution

The time-scaling of a rhythmic object, also known as augmentation or diminution, replicates a given rhythmic object in a different temporal scale. It is carried out by multiplying a sequence of a duration-values by a given scaling factor, making the same rhythmic object sound faster or slower.  Just like scaling a photo, applying an augmentation value to all duration values of a rhythmic object, for example, is the equivalent operation to scaling an image by 150%.
