Caddy Exhaust Sounds
I finally got around to putting up a WAV file for my caddy's exhaust sound. These are Borla ProXS series mufflers and a 49-state OBD II compliant high-flow cat. The IT was a bit of a project; I moved the electret microphone from my main computer to my laptop (which I rarely boot at home and don't have a place for there), found my sound hardware's application folder, set it up for the electret, and tested. I then moved the whole thing to the garage.
The car was stone cold so I let it idle for a few seconds before revving it, and the maximum RPM was 4,000. The sound file seems to have the bass coverage to give an accurate sound when I put the file on a CD and played it in my living room through my Bose 901s. It woke up my wife and all four Chihuahuas ran for cover and didn't come out for some time. It sounds a lot better in my car's Bose system.
I put the file on commercial web space. Accessing this file may not keep up with real time. If you have trouble with halts or listen to the file more than once, please download it to your computer and listen to it, or put it on a CD, from there.

Bruce suggested OneDump.com and I found that 13 MB was too big. So, I cut off the part before I touched the throttle and after the engine shut off, and put a link there.

In the process of working with the WAV file I found that it clipped quite a bit due to high low-frequency sound volume. The result is harshness that is audible on computer speakers from sound that is not audible on computer speakers. I'll make a better WAV file in the next few days and edit this post. This time, I'll warm up the car first and put the microphone ten feet from the car, not three feet. For now, both links stay up.
UPDATE August 6, 2007
It's going to be a couple of weeks before I can get to making another WAV file. There will be big changes by the time it's up, including moving over to FIOS so the download rate from my computer will be 5 MB/s instead of the 1.5 MB/s it is now. I'll have another update before I replace this entire post and the links to the existing WAV files. For now, get the long one (right click on the link, select "save" and save it to your computer), burn it to a music CD, and play it on a living room stereo with good speakers or headphones, or a Caddilac with a Bose system. The note at idle is faithful, and the clipping doesn't start until I rack the pipes.

I moved the files to commercial web space. They should both be easier to listen to now.
