A Symphony of Power

Ken, I'd like to hear more of what you do with soundboards. Where, what, when, etc.

lol

I look forward to hearing it. If I find the time, and have sufficient audio samples to work with, I might incorperate these in to something else I've been playing around with.

Someone bring an iPhone to the next club meet!

Why be limited to just audio... video FTW!

My experience last year at a couple of autocross sessions, was that for the best audio recording of the engine/exhaust sound, the mic needed to be located by the rear license plate. Not only did this pick up the audio you wanted to be recorded (ie engine/exhaust, screeching rear tires), but it also eliminated the audio you didn't want to be recorded (ie keys/keychain rattling around, gawd awful wind noise, etc).

A stereo recording device would be best, but here's what my $10 spycam with mono audio recording captured last September at the Corvette club's autocross with my mighty duke (dual-exhaust, gutted cat). Crank up your volume!

Well, the main point I was making was that the best place to record what we want to hear is from the back of the car by the rear plate.

Portable standalone stereo audio recording devices such as This are really nice. Who's got one?

Whatever device is used for the recording, it's not a big deal for the end user to do a file conversion to suit their needs.

Alright then, someone make a bracket to attach an iPhone to the rear plate location of their Fiero, and let's hear how it sounds!

Well, you don't want the device to rattle around at all, otherwise you'll get all kinds of noise you don't want.

I used hockey tape to hold my spy cameras in place. The tape held well, but it was difficult to aim the cameras exactly where I wanted. That's not as much of an issue with audio-only recordings, but it's something to keep in mind for those who wish to shoot video as well.

Honestly Tristan, that's a lousy way of doing it. So many guys post YouTube videos of the back of their cars parked in the garage while they rev the crap out of them.

I want to hear these engines rev while under load (like on a dynamometer). That sounds completely different (and better) than some engine being floored while just sitting there freewheeling.

Ken, maybe we could get Tristan to run behind everyone's car with your camera.
