484 Assignment 4
Implement a limiter using the ideas in the text Figures 5.3 and 5.8
including attack and release) and
test it on one voice file and one drum file from the table below
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.
Parts 2 and 3
Repeat Part 1 for a compressor/expandor and noise gate, using the
ideas in the text.
Implement an audio effect using SSB (either Figure 4.13 or 4.16) and
use it on one voice and one drum file from the table above, plus the
flute2.wav file used in Assignment 1.
Try 3 different carrier frequencies, approximately 1, 100 and 10,000
Document your code and explain the results. Post the input and
output sound files, software and text file on your website.
