Blumlein Sennheiser mkh 30/30

freitojos 28 January 2012 sennheiser, sennheiser mkh 30, blumlein,

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: [="http://soundcloud.c…"]20110610T0600Z, TORDUS MERULA AND FRINGILA COELEBS by freitojos on SoundCloud - Create, record and share your sounds for free[/]="http://soundcloud.c…"]20110610T0600Z, TORDUS MERULA AND FRINGILA COELEBS 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 Waveswith the same frequency and diverse amplitude cancel each other? To cancel they must have same frequency and amplitude?

The answer is quite simple. You go for a sound that you want. Sometimes spaced omnis are what you want. That in addition to a shotgun microphone that's highly directional to focus upon a particular sound. There is no right or wrong way to do this. These microphone techniques are not simply applicable to indoor orchestral recording, they are universal techniques. So if you think cross coupled figure of 8 is the sound that you want, you do that. Any closely coupled microphone diaphragms will lower phase cancellation but out in the wild, you can do and attempt most anything. You would however want to collapse your mix from stereo to mono to make sure that nothing is canceling that's important. But when capsules are extremely close as in XY & MS Stereophonics techniques along with Blum, their capsules are so close together it is to prevent phase cancellation. If you want a larger stereo soundscape then maybe a pair of spaced omnis along with the shotgun directional microphone would better provide that for you? You actually have a multitude of different ways to get what you want.
