Audio clip - classical guitar recording - AEA R88 + Soundfield - any comments?

Same here. This was a bit of experiment and, unfortunately, my main pair--which were a pair of Schoeps MK21--have all sorts of phase problems. Not sure why - maybe caught in a dodgy node in the room which I didn't notice at the time!).

Hi Douglas,

I'd contact Soundfield regarding any noise issues, my 422 went in for a service recently and they "upgraded" some components in the microphone and processor.
My find my 422 very quiet indeed (I have the stereo version), maybe a service is required? Their tech support was fantastic.


Cheers,

What we have done before is sample the hall/church at the distant mic position. That way you can add the same reverb (if done properly) with two distinct advantages:

1. no hiss
2. you can edit out the 'second' or double direct sound. You can just use the reflections/diffuse portion of the sampled acoustic.

3. No phasing problems associated with a second set of mics.

How would this rule apply in a solo instrument recording?


I also like a lot the dry sample. I would like to compare with a sf12 take. I guess that there would be a bit less warmth and a bit more definition ?

Well that definition is not exactly what the 3-1 "rule" is. The same applies to a single source if you are using a room mic. Though it is one of those guidelines that has as many exceptions as applications.

I think this is one of those things we tend to worry too much about for little reason. Especially in this instance where we are talking about a highly directional figure 8 ribbon and a distant stereo mic in a reberberant space. Phase problems should probably be last on the list of worries.

I don't mean to be condescending, but a rudimentary understanding of wave theory would go a long way toward answering that question.

Well, I might have a bit more that a rudimentary knowledge of wave theory...
