Blumlein

Do you need an encoder to do Blumlein? Or just simply 2 mics that will do fig. 8?

No encoder necessary.

Nope, no encoder required. Just two figure 8's at 90 degrees of each other.

The Blumlein pair produces an exceptionally realistic stereo image, but the quality of recordings is highly dependent on the acoustics of the room and the size of the sound source.

thanks that is what I thought

Blumlein is my favorite stereo configuration. It is the most natural (well balanced tone & direct/room signal), perfectly mono compatible. Even in a poor acoustic room I had great results. Enjoy.

Me too.

Though I rarely use it anymore.
Maybe I will now. You've inspired me!

I really like well done Binaural recordings.

Here's a fun little example of a Binaural recording. You have to listen to this on headphones though. Do not attempt to listen to this on your loudspeakers...

Actually, Blumlein himself actually used two fig-8s in MS a lot of the time.

Doing it this way means that you always get two fig-8s crossed when matrixed to stereo, but you can "steer" them to widen or narrow the image.

If I was doing crossed figure-8s I would do it the MS way with a matrix.

I tracked drums in 3 songs for a client recently using Fathead 11's in blumlein (room mikes) - 2 of the songs the Fatheads were in phase with each other and with jigging with overheads..

On the 3rd song, I could not get the second fathead 11 ( pointing away from drum kit) in phase with other Fathead in the blumlein pointing at kit (despite inverting phase) and get it in phase with overheads as well. Turned the secondary non direct kit fathead off on the 3rd song.

Wierd- in other 2 songs with same mikes and same preamps and compressors, kit played differently, (more soft- 3rd was very dirty and I told the drummer to give some smack) but I could jig both room mike fathead 11's blumlein into phase with M160 overheads.

Stuffed if I know- I know what my ears tell me-why would the 3rd song have phasing issues on non direct fathead 11 - maybe somebody could chip in and explain why this happened.

not sure i understood the question correctly, but it seems to me that you are pointing one mic directly at the kit and the other mic is at 90 degrees to it. This would not be the correct way to use the blumlein technique. You should be pointing the center of the 'x' (formed by crossing the mics) at your instrument.

the technique you have used however would have resulted in an m/s encoded recording, which you can decode easily (plenty of info available right here, just do a search).
