Hello all!

I'm kind of an anomaly as I don't record music, I record cars and motorcycles.

I had a simple, newbie question: I recorded a Ducati over the weekend and when I played it back through my software (Sony Sound Forge Audio Studio), I noticed the sine wave was flat on the top and bottom at certain points. I'm thinking that the sound got clipped as the input might have been too high but I wanted to defer to the experts. The recording was done 44.1k/16 bit in wav format if that helps at all.

Thanks for any and all help!

Except for some of your nomenclature a Ducati can produce a substantial amount of DB's. This being the case, there are a number of factors here for good recordings. A condenser microphone & a Ducati will generally become overloaded without the use of a built-in microphone pad. Even if the preamp has a pad, the microphone will need one also. Not all condenser microphones include "capsule pads".

Then there is the problem of overloading the front end, of the microphone input. For that, you need to engage the pad. If there is no pad? You'll need some kind of gain sensitivity adjustment. Whether it's a switch or a continuous "volume control" knob. You might even want to use a dynamic microphone instead of a condenser microphone? Those don't overload and are easier on the inputs of some microphone preamps.

Now I said nothing about the kind of sound you are trying to utilize this effect for? Is this a bike in motion? Or just the engine revving up? On a dynamomurder? That's a capital offense you know? I love my mother & my 82 Honda Silver Wing very much and would not like to be without either.

I don't know how to rebuild my carburetors?

I record with an Edirol R-1 with a tiny condenser lapel mic and a battery filter module.

Than at the risk of a reduction of the signal-to-noise ratio, I would have any kind of a pad engaged. If I had more than one pad to engage, I would. Generally, you don't have to worry about signal-to-noise ratio when dealing with loud motorcycles. So always tweak with the thought that any close proximity microphones will always be overloaded along with their respective microphone input. So lower is better no matter what you are ET may be.

I don't race mine. I'm slow goin'

Thanks for the info! I'll just try and record at lower levels....
