Re: [Sursound] Array for sound field recording and extend the sound image

2013-01-09 Thread Dave Malham
Hi Tim, Indeed, SNR is poor at low frequencies for this sort of technique as it relies on the phase difference between the two capsules as produced by their separation. The separation can't be too large as once it gets over half a wavelength the phase starts wrapping around but this means that at l

An open paper on directional mics http://www.iwaenc.org/proceedings/2001/main/data/buck.pdf I had a idea that I could use 2 close mounted mics (o) for Upper frequency ranges and a longer distance between 2 additional elements (x) to have better signal to noise ratio for the lower frequency band
