  1. yeah 2.5 ft is pretty close but sometimes a soft trumpet line will end up that close.
  2. Hey Captain. Like i said. Its usually a ribbon, (dx-77s, R-84s, Coles 4038s) but some times dynamics (57's, AKG D12s, 421s) I reckon I've seen it on most microphones. In most instances I end up with the microphone somewhere between 2.5 and 3.5 feet from the bell of the horn and tilted slightly of axis from looking straight down the barrel of the gun so to speak. Preamps usualy Neve 81 series at one studio or another. Or I might use the AEA ribbon pre (TRP) for super clean tracks. It doesn't seem to make a difference. I'm almost convinced its got something to do with the acoustic property's of the wave front of brass instruments. I must stress that I'm not convinced its really a big problem. The horns sound good and i don't think its putting enough off-set in my mixes to hurt peoples speakers or anything. I still seem to be getting enough dynamic range to give the horns a good squeeze with a compressor. I just find it odd. No other sounds do this. Ive thought about the fact that maybe at the beginning of a horn note there is a single loud burst of pressure that forces the ribbon of diaphragm into a wild swing before it starts to vibrate and produce a note. but then i thought you'd only every really see that for a moment. The DC off set i see is sustained all the way to the end of the note. So i feel forced to to feel that there is some really weird spooky property about horns that can consistently hold a suspended vibrating element in compression and establish its own 0 line on top of this. ????? What else does that?
  3. Actually I have noticed it in one other persons session working at the one of the same studios.
  4. hey Captain Terrific Well I suppose I'm just talking about my own. I suppose in theory you'd be able to make out a dc offset in a stab on a master unless the mastering engineer has done some dc off-set magic. Ive noticed it recording different players in completely different studios and also at my home studio. So I guess I'm kinda convinced it just happens and its not as a result of something that was off on a particular day although id love to have this confirmed by other people. I'm more just plain curious as to why it happens. Cheers. T.
  5. So Ive been recording for a while now and i remember i discovered this weird thing a few years back and I've never got a good answer about it. Whenever I end up looking at a waveform of brass instruments there is almost always some kind of DC off-set ranging from minimal to ....well lots. lets say the waveform looks like its at least 2/3rds on the compression side of the 0 line and 1/3rd on the rarefaction side. This is is no way a problem for me I'm just curious to see if there is an interesting boffiny type answer as to why the wavefront of a horn produces so much DC off-set at a microphone compared to other high SPL sounds. Usually I'm using ribbons but Ive found the same thing with moving coil mics. Also I find its the same if i go straight to the computer or if the sound lives on tape for a while before i dump it into the computer for whatever reason and end up actually looking at the recorded waveform. Any Clues? Cheers. T.
