Probably a tire/tyre or meter / metre scenario, I don't know. I've only started to see it here in the last year or two, and it's likely another time when the general public has bastardized proper spelling and forced the "powers that be" to acknowledge it as "acceptable".
Anyhow, yes nice work Todd. The first one sounds extra nifty!
No problem, I was quite flattered by the notion actually, so thanks
In order for somebody else to listen to it I had to record it somehow of course. Either that or pop the program in here which I preferred not to do.
I see. Quite frankly, I wasn't sure what I was really looking at in that graph you displayed.
Yeah, there is a high pitched ringing there at idle. This is actually a resonance phenomenon happening in the exhaust system that's causing it. It can be tuned out pretty easily though.
Thanks for the kind words, everyone.
[edit] Oh, and the spelling I always knew was apostrophe
