I would like to know your opinions about the use of the coincident setup above (blumlein) in nature soundscape recording. For now I am using mkh 30/40 ms setup in a parabola, here are two results: 20110610T0600Z, TORDUS MERULA AND FRINGILA COELEBS by freitojos on SoundCloud - Create, record and share your sounds for free 20110528T0615Z clamater glandarius, male and female wav by freitojos on SoundCloud - Create, record and share your sounds for free I want to listen my recordings in speakers not in headphones so I want the best stereo possible and I know some blumlein recordings are the best stereo possible but they are made with a band or orchestra in a stage and as I know they require a good room. In the nature there are no stage and orchestra and of corse no room. Do you think blumlein coincident would work in the open space (mkh 30/30 45º) alone ? And in a parabola: the rear lobes in focus with the amplified sound and the other two lobes capturing the same sound not amplified? Does I am going to have phase problems or cancelation? Does two waves with the same frequency and diverse amplitude cancel each other? To cancel they must have same frequency and amplitude?
