Abstract

The analysis of an anthology of Canadian computer music is presented. Praat scripts analyzed durations and intensity rate changes of successive rises and falls in the pieces. The main parameters determined are the duration of each pair of rises and falls in the 'all peaks' and 'significant peaks' approaches, using the indicated time windows. The overall times occupied by ramps and damps are also computed for each piece. The statistical significance of the hypotheses that the ramp-damp time log-ratio and the log(crescendo-rate/diminuendo-rate) differ from 0, is tested for each sound file in each data set. The hypotheses that rises are longer than paired falls is not supported and they are generally shorter. Determinations of the average lengths of crescendi and decrescendi in individual pieces are in 34 cases indicative of shorter and only 7 longer crescendi than decrescendi.
