If you want to stretch the signal longer, you will need to apply the effect to a longer selection and then trim it, rather than the other way round. When stretching longer, the resampling interpolates new values between each successive sample value. The problem at the end of the selection is that th...

If you're looking for best sound quality and price is not an issue, take a look at the range of DPA omnidirectional miniature microphones. They do some models that can handle well over 150 dB SPL with extremely good sound quality, but they are not cheap.

If I stripped off the mount and just used that on a clamp bracket or just gaffer taped it to the car, would that mic be ok to use with the H1 in terms of signal? I wouldn't. A shotgun mic might be OK for recording the cars as they go past, but I wouldn't use one taped to the car. I think that cyran...

A cheap option that you could try - earbud headphone can work like microphones. They are not designed to be used as such and have very low sensitivity, but in this case that is exactly what you want. You could try plugging a cheap set of earbud headphones into the mic input of the H1.

So in effect is it the SPL which is too high in these environments? Yes, that appears to be the case. If I bought a mic with a much higher SPL would that help this problem? There are two things to consider: 1) Can the microphone handle the SPL without distorting? 2) Can the H1 handle the signal lev...

Well, I'm not sure your criteria for a bug is mine. It seems to me that when I enter data into a field that is what should appear in that field, no matter which program i use... Until all software uses the same metadata standards, that is an unrealistic expectation. Some applications use ID3v2.3 ta...

The H/M/L sensitivity thing works up to a point, but I'd not be surprised if close recording of a racing car pushes the sound level beyond that point.

It sounds like it is picking up some interference from your computer.

The problem looks like "clipping" distortion. Clipping occurs when the signal level is too high for some part of the recording system and the top and/or bottom of the waveform is "clipped" off. Notice how flat the bottom of the waveform is in the bad recordings. I don't have an H...
