Exercises

Copy the STK classes, Clarinet and ReedTabl, to your project directory. Study, modify, or write new code there to do the following problems.

1. Plot the reed-table output for input argument from -3 to 3 (in small steps) of the ReedTabl class. Verify on your plot that the slope and the offset in the reed-table correspond to its default values. Also submit your code.

2. Modify the main program from Elecguitar homework, or any program, which can take the SKINI file fiddle.ski as input and play the song with a Clarinet (hint: You only need to change the instrument). Listen to the effect of changing the slope of the reed-table and describe the change in timbre, or document it with spectral plots. Describe how such a change in slope could be caused by changing one or more physical parameters of the reed.
