Mixing after having recorded with a stereo technique: ORTF, XY, NOS, Decca Tree, Blumlein, AB

Member for

There are tons of discussions about these stereo techniques (RTF, NOS, XY, Decca tree, Blumlein, AB) but I did not see much with regard to the mix once used them after recording.
After one has recorded using one of these stereo techniques, what procedure to follow in the mixing process? Logically, the tracks should already reflect the stereo effect ... but if we are not entirely satisfied with the result:
What can one do with the 2 tracks in the DAW? If we do not let them as such, at 0 in the mixer, how much panning after each technique?

best mic arrangement to blend off centre source to main ORTF

I am going to record a concert of the 'Armed Man' in a large church.
The main stereo pair will be flown above+/- conductor position (MC930/ORTF)

A childrens choir of ~70 will be placed in a side aisle outside the pillars even but level with the choir/orchestra in the Nave. This choir will be angled towards the conductor in the centre aisle/Nave, so at ~45 deg to an imaginary centre line down the church.

Phase issues with ORTF technique

Hello experts.

Misa got a question. How far are the mics placed from the soundsource when using the ORTF technique?

I tested it and noticed some phase issues.

This is the setup I used:

Recording acoustic guitar
2 pencil mics angled 110 degrees and distanced 17cm (6.6 inches) apart from each other
The mics were positioned 30 cm away from the guitar (12 inches)

According to the 3:1 rule these technique should generate phase problems. ¿Am I right?

ORTF/MS Phase question

I have a wind band recording I am working on (70 piece). While it is quiet, the room isn't that great, so the "hall" isn't helping so much.

I have a pair of DPA 4011 in ORTF and a Schoeps MK4/MK8 MS pair on the same bar. I put them up just to A/B them. I have outriggers, but am not using them very much. they are Cardiod Schoeps MK4. There are various spots in the ensemble as well.

Blending Blumlein and ORTF Choirs

I'm preparing my mix's for the choirs I just finished recording.

2 DPA 4011A in ORTF
1 Royer SF24 in Blumlein
1 Audix M1280 micro condenser for added detail

Any suggestions of how you blend blumlein and ORTF?

John, did I hear you right... choose which of the two that sounds (fullest, widest most detailed) and add the other to taste?

Any suggestion?

Royer SF-24, DPA 4011 ORTF for Choirs

I've discussed this more than once but wasn't sure what mics I'd settle on and know how the room would sound with people in it until yesterday.

Recording 14 choirs over 2 days. Largest choir will be 75 people.

Small choir test
Last week using two R-122's in Blumlein about 20 ft back from the choir, 2 ft above top head level for a test run sounded pretty nice.
The 40 ft ceilings in a barn style church make it a bit reverb heavy so what are some ways to tame this a bit?

The ORTF stereo technique provides the recording with a wider stereo image than XY stereo and still preserves a reasonable amount of mono-information. Care must be taken when using this technique at larger distances, as the directional microphones exhibit proximity effect and will result in low frequency loss. You could add low frequency with an Equaliser to desired taste.

Choir with MKH8040 ORTF

wonder if you could give some feedback on the below Choir recording. This was done during a rehearsal yesterday in a midsized stone church (Reverb around 2.5 sec) with a pair of MKH8040's in ORTF
The concert is on Sunday so hopefully with your input, I can improve on the sound some more!
