Music 220a -- Homework 2


The brass tube length is about 0.61 meters. The duration of a cycle in the waveform (after the initial impulse) is about 0.0035
seconds, so the speed of sound would be v = (d / t) = (2 x 0.61m) / (0.0035s) which is about 348 meters per second.


The settings for the synthesis using the echo.scm script are as follows:

       delay length = 0.0035s
       attenuation  = 0.9

The waveform looks like:                                                                                                                                                            Sound
