Testing for system resonance
Does anyone know how to test for resonance fq's for a mac system?
I can choose a sine wave from the analyzer in Soundtrack Pro, and sweep the fq thru the spectrum, but how do I measure the volume result? It only puts out the volume that is selected.
It might show a fuller set of harmonics with a square wave, but would this really vary with fq for my system? I want to find the dominant frequency of my system, if there is one. Then, I want to find ways to adjust it or filter it out.
For example, the best old Martins have been found to resonate at around 400 Hz, and the worst acoustic guitars resonate at 100 Hz. The even harmonics for 400 Hz would be 800, 1.6k, right?
Also, does anybody know if CPU speed, or FSB speed, has anything to do with audio resonance for audio files? I used to get some pretty weird resonances in GarageBand on my mac mini that might not have ever been generated on a larger box.
Any info would help me decide which Mac to upgrade to.
