Topic: crossed hypercards..?

[macdaddy]

assuming that the angle between the mics remains unchanged, you're not picking up a wider angle of sound since you're actually narrowing the mic pattern by using a hypercardioid instead of a cardioid.

right - but i was actually talking about going from fig 8s (blumlein) to something else when need be, and i am trying to decide when that time would be - and i know it is when i am set up off-center, and thus the soundstage kind of blows...

If you are trying to keep a similar stereo spread on playback, then cards would need a wider angle than hypercards, which would need a wider angle than figure 8's.

so if i need to increase the included angle of the caps from 90 degrees (and set @ blumlein, which i prefer) to whatever i need to get the appropriate spread of the soundstage, i should dial the caps from fig 8s towards cards, and the wider the angle, the closer i should get to the cards...

when would i need to be using the patterns between card and omni..?

thx again.

Yes. Blumlein is an odd case where the angle between the mics is the same as the stereo recording angle.  For other patterns the wider the angle between mics the narrower the recording angle for the sources to be evenly distributed between the speakers.

For a coincident setup, you'd probably never use a pattern more omnish than a card, unless its the middle mic in a mid side setup.

I too have noticed the benefits of a quasi-blumlien effect with hypers x/y.
