I recently spent a pile of cash on new home stereo gear (VMPS RM-2's and 626's), and I've decided to get serious about configuration (for the home) and equalization (for the car).

To that end, in a fit of Hack Attack, I took a cool tool called Sonic and hacked up some frequency sweep generators, including warble tones, since that seems to be something the stereophiles care about. Here's the source code, which should compile and run just about anywhere (I was doing it under cygwin on Win2K).

Questions for everybody here, now that I've got this tool:

- If you could have MP3 files with any frequencies, sweeps, warbles, and so forth, what would you want?

- What are the center frequencies for the RioCar equalizer in its default 5-band or 10-band configurations?

- What algorithm would you use, given the aforementioned test tones and a Radio Shack SPL meter, to tune your car stereo? Your home stereo?

- Are there any web sites out there that explain how to do all of this? I've looked and found nothing particularly enlightening.

Thanks!
