ELEC 484 Assignment 4

Part 1

Implement a limiter using the ideas in the text Figures 5.3 and 5.8 and
test it on two carefully chosen sound files (e.g. voice, drums).
Adjust the parameters so that the limiting effect can be clearly
heard.  Clearly document the algorithm and your code, and comment on
when and how the limiter is working.  Plot the static gain f(n) and
dynamic gain g(n), along with the input waveform, level measurement and
output waveform.  Post the input and output sound files, software and
text file on your website

Sound samples may be found at www.findsounds.com and elsewhere on the web
using search terms such as "free sound samples", or you may already have
your own collection of sounds.

Parts 2 and 3

Repeat Part 1 for a compressor/expandor and noise gate, using the
ideas in the text.


Part 4

Repeat the vibrato exercise (Assignment 3 part 4) using a real
instrument such as a trumpet or flute.  Post both the original sound file
(with no vibrato) and the processed file.  Choose the vibrato parameters
(depth, rate) to yield a pleasing sound.
