ELEC 484 - Audio Signal Processing
Experimenting with Digital Audio Effects
Create a 15 second "sound collage" as a .wav file
Download all Matlab code from the
textbook web site. In the
for Chapters 1,8,9 there are .wav files as well as .m files
Download the audio editor Audacity from
Learn to use Audacity. To start:
Assemble a sequence of audio segments in one audio track,
and use audio effects
to modify them
Create a 15 second track which is "interesting"
Write a half page description of what you did.
Post links to your audio track and description on your course web site.
More detailed instructions are provided
Marking will be partly objective (did you use the audio effects)
and partly subjective (is the result "interesting").
Under "Help", choose "on-line help" and read it
Under "Generate", select "Pluck", and an audio track will be created
Play this track using the green "Play" button
Under "Effects", choose "Change pitch"
Play this track again, and notice the pitch change
select one of the .wav files downloaded previously from the DAFX site,
and the waveform will be displayed as an audio track.
Edit this waveform using the tools described in the on-line help.
For example, cut out a 1 second segment, and apply pitch shifting
to that segment.
