==== Analyzing Results ====
* What is the impact of various optimization levels on the software performance? (For example, -O0 / -O1 / -O2 / -O3)
* Does the distribution of data matter? (e.g., is there any difference if there are no absolute large numbers, or no negative numbers?)
* If samples are fed at CD rate (44100 samples per second x 2 channels x 2 bytes per sample), can each of the algorithms keep up?
