Re: Audio Micing Church Choir
 

"I'm in "post mode" now and trying to figure out how to share my stuff to someone with a PC and running Vegas (version unknown) while I'm on a Mac. And I hope to get his audio and video for my editing."
- Vegas Pro 9 and above can export/import AAF files. I've exported to Avid MC and SlowTools successfully but not the other way around (importing AFF into Vegas). I've also gotten OMF (audio) files into Vegas Pro using AATranslate, a third-party converter, as VP does not support that format (despite requests by myself and others since Vegas 1.0). For video, you 'could' just ask for a video with a single frame A/V blip (bars & tone) for sync /line-up and/or a reference audio track to manually sync it to,

Re: Audio Micing Church Choir
 

That video is a good example of how a decent sound source can make up for the technical things that are often talked about as 'rules' - the miking with the angles and spaced capsules, plus the colouration that as mentioned is present on larger diaphragms is totally outweighed by the choir sounding good in a fairly dead space. Can we hear the colouration? No - I don't think I can. How about the well known hole in the middle from the separation of the mics? No - can't hear that either. The physics says they happen, and we all sprout the physics, but this is a fine recording and the small issues are not the recordist's fault - any mic, any technique would have captured them.

The detail is present - the stereo image is quite wide, but I'm pretty sure I could hear one fella second row near the middle when he clearly sung one little phrase, and he is where you'd expect capture to be weaker?

This sums up so much what I firmly believe - the differences between mics, mic technique and subtle changes of angle is VERY small, once you get close to the right place. Very often two mics, of average quality and similar polar patterns - as in the same model, but not matched, actually work fine - the mismatching producing tiny left right shifts that very few people would notice. All the physics is solid, but the consequences often exaggerated in practice. The baby crying at the end made me smile - captured nicely!

Re: Audio Micing Church Choir
 

Thanks. I put up this example to show (to John) that a serviceable recording can be had with just a pair of 414s. Yes, there be warts in this live recording, the abominable concert hall not being the least of them. I'm also quite certain that I didn't optimize the microphone spacing and angle (set up time was short). Finally, the 414s are a sizable chunk of visual clutter. I've long since abandoned these as a main pair in favor of far more discrete SDCs or, if the hall is nice, a spaced pair of omnis.

Re: Audio Micing Church Choir
 

Wire hangers can be cut, bent, and shaped to hold things taped to them - even to the point of being an improvised mic or camcorder mount in an emergency. Or maybe substitute for a broken tail pipe hanger on a car. The uses are endless.

On factor in the recent photo is the choir is arranged in an arc (near semicircle) with the mic at the center. This helps equalize the volume of each singer. With a linear chorus arrangement the singers at the edge are further away, and thus weaker. Not an issue for the audience, but it is for a single point mic.

As long as the listening is in stereo the comb effect of spaced mics is not an issue. A wide stereo image if widely spaced mics (according to the 1:3 rule, is not all bad, and helps with the issue of a long linear chorus.

I agree that the coloration and any mismatch of the AKGs would not be significant in the grand scheme of things. It would take a golden ear in a studio recording environment to notice. Try them some time when you have a chance in a practice shoot. You have what, 11 months, to sort it out before the next December concert.

I exchange files (both video and audio) with a Mac person using thumb drives (I do Windows PC). Low cost, large capacity, and easy to snail mail. The only issue may be if he can read the files you export depending on his software tools and OS version.

Re: Audio Micing Church Choir
 

That's a bummer because that's the closest I've got to a pair of mics that could produce a stereo track. The Røde Stereo Video Mic could do stereo but it's not near the quality of the AKGs. Will have to explore options and tradeoffs. Would like to avoid buying more mics, at least for the time being.

One option might be to pick up another 414 - wouldn't officially be a 'matched pair' in audio parlance but since their quality control is pretty good it might be close enough for Government work. Or should this option have been put in the form of a question?

I liked the curved layout of choir and the acoustic panels.

After watching the video I wound up watching well over an hour of various other choral groups. It was interesting to see how their mic(k)ing setups were and their layouts. In the end I wound up watching one titled (I think) "Vienna Christmas 2008" which was absolutely awesome!!! Everything about it - the singing, the orchestra, the setting, videography, ... was really nice. What a difference between the old buildings then and the new ones today. Sure, the new ones have acoustics aided by computer input but the beauty of the old buildings is really nice.

Talk about mics, they had a lot of them. Tried to read the name on one but my screen resolution wasn't quite there.

Re: Audio Micing Church Choir
 

I thought about this topic watching the Christmas Day Carol Service from Kings College in Cambridge - and it's a wonderful building, but one where you would not want to listen to a single person speaking - the acoustics are wonderful for this kind of thing and sounded beautiful on the TV. Plugging in my stage in-ears I was surprised at how confused the actual stereo field was. As it was a TV product, clearly stereo imaging meaning very obvious miking was out, and the physical distance from organ to the choir meant all kinds of wonderful timing errors - so bad that the conductors arms rarely coincided with the real timing. The audio lip-sync with the choristers was clearly the important sync element - so this was where the effort went, and although I clearly don't know for certain, I think the organ was recorded in stereo and blended in - which messed up the soundfield. If you close your eyes you couldn't really determine which direction you were hearing - as in a left right split down the length of the building with the choir on both sides, or the left right line running at 90 degrees. It sounded gorgeous because the music and the building were in harmony with each other - but it was a very manufactured sound. They did it very well, but I wondered how they would have done the same service if it was for radio?

Re: Audio Micing Church Choir
 

Hey Paul! - really enjoyed your analytical critique review, and after doing this project I’m in the same mode. I’ll never be able to watch a program like this again without searching for the mics and looking for the little missteps.

Critique isn’t all new to me, though, ‘cuz watching the musical Oklahoma with the passenger train surrounded by attacking Indians whilst passengers were singing with arrows flying though the passenger car windows didn’t seem all that real. That was obvious but audio critique requires more attention to detail.

Thanks for the name - I'll have to do a search for it.

“It’s all about money.” When they set up and do this every year it should hopefully make the production a bit easier, and newer technology helps. The also had a sprinkling of English songs possibly to appeal to a wider audience, but then there are many University courses being taught in English.

I explained to others in the house, here, about the mic locations (and got them looking for them too), and explained how fast sound travels (does not travel at the speed of light), and the difficulties with syncing. Don’t know if it ruined their viewing experience or not, didn’t seem to, though.

All in all, it was an enjoyable program. Started to watch the 2016 version but actually liked the older 2008 version better. Oh, and the women here zeroed in on the soloist’s red dress (they liked it).

After doing this project I'll never watch something like this the same way again!
Edit: Found some videos from King’s College, f.e.: O Holy Night - Carols from King’s 2017 Very nicely done.

Awesome chapel! Also noticed the design of the ceiling - looked like a challenge also for the builders. For our American readers: (Wikipedia https://en.wikipedia.org/wiki/Choir_of_King%27s) _College,_Cambridge Founded in 1441 by Henry VI of England and it has an interesting history. “Particularly long reverb”

On the video side, it is also interesting what various videographers do to avoid a constant wide shot, for example, a slow zoom in and pan across the choir then a zoom out, such as that done by Steven Reid in his video. This particular technique would be especially useful when sharing the video with chorister members later. (Learning something all the time!)

Re: Audio Micing Church Choir
 

It's a great and wonderful building - and really old. There is a website for information about the building and when it was built.

Chapel | King's College, Cambridge

For music, almost anything sounds great.

There's a youtube video of the organ where you can hear the amazingly long reverb tail and the acoustic mess (though nice sounding) this causes to music that has fast articulations.

Re: Audio Micing Church Choir
 

I assure you that the genesis of my shooting 'technique' resides solely in the limitations of my using just one camera. I generally disdain zooms and pans while rolling, but they are preferable to the monotony of a locked-off wide shot. As a one man band, I can only do so much. In contrast, the splendid video of King's College you posted above is obviously the work of a team of videographers and several cameras, some of which appear to be unmanned. The few pans and tilts are rather tastefully achieved, I think.

Merry Christmas!

Re: Audio Micing Church Choir
 

The PBS station I used to be on staff at did a presentation from Kings College a number of years ago. We sent representatives from our station ( TPT in Minnesota) to oversee the recording and video taping, then did the post production in our facility. It was a nationally broadcast program. The big challenge was the lighting as we were only allowed to use the available light from the candles in the processional and video cameras weren't as sensitive as they are now. I remember it sounding really nice, and in spite of the limitations it looked great too. I looked for it on line and couldn't find it. It was called Christmas at Kings and was recorded about twenty years ago.

Re: Audio Micing Church Choir
 

One of my earliest broadcast jobs was lighting (well, in truth at that time it meant heaving huge quantities of kit an and out of locations) and the cameras in the 80s needed huge amounts of light to get decent depth of field. Narrow DoF then was the enemy, unlike today. At many churches there was nowhere to put the lihts and no power available for them either - and the gaffer had an assortment of cut down nails he routinely swapped for the fuses!

Re: Audio Micing Church Choir
 

I came across this documentary on YouTube last year about the Christmas Lessons and Carols service from the chapel at Kings College Cambridge. There are a few technical details in the doco and I found this one quite fascinating:

So the choir can read their music, there's a light bulb under the candle and the light comes down. And what the first lighting director and I devised was to put in a ring to raise the candle an inch or so up so that we could have a window [with diffusion] so that light could shine out from the bulb towards their [choir] faces. But it means the light (lighting their face) is coming from where you expect it. -- David Kremer, Director

Re: Audio Micing Church Choir
 

This has been a fascinating thread and many thanks to all of the links. I have been trying to take audio recording more seriously lately. The problem that I deal with is that these choir festivals tend to have choirs of all different sizes and there are no breaks between choirs to make adjustments, so I have to make a good middle of the road effort on mic placement. I have typically just used a matched pair of Rode NT3s on stands that are set up about 20 feet apart. However I have been thinking of adding another pair to the setup using an X/Y configuration in the middle and then having the other two further out. (I have been advised to angle the outer pair more directly at the edges of the choirs to avoid overlapping with the X/Y setup). This makes sense to me, but I was going to ask what others thought about having a 4 mic set up with:

a) choirs of different sizes/shapes and no time to re-position mics
b) a piano sitting there on the stage just off set from the middle
c) Do not have any 20' booms. (Just 4x K&M extended boom stands)

The problem that I foresee with the X/Y pair is the piano sitting there, upstage. Relatively speaking, the room is so narrow, that maybe I'm better off with just the one pair of mics? I have attached pics of the space. Thanks for any advice!

Re: Audio Micing Church Choir
 

Another picture that shows where the piano is placed.

Re: Audio Micing Church Choir
 

I use M/S rather than X/Y for most concerts - so far I've had absolutely no problem with a single coincident pair covering an orchestra of 60 - 70 musicians.I suspect if I were trying to record a space like Radio City Music Hall I might need more. I sort of rely on the fact that the conductor will manage things so the music sounds right at his/her location, so the closer you can get to the condutor, the better.

Re: Audio Micing Church Choir
 

I agree that an M/S mic is a good simple choice and I have done numerous concerts using a basic set-up of a Sony ECM MS-907 or 957 straight into a canon HF11 camera as a locked off wide shot and using the small camera as an audio recorder. I have also used both mics and an old mini disc recorder for lots of TV sound capture and recording.

The advantage of the Sony mics is that they are M/S capsule wise but then output an A/B signal for recording, you can also adjust the width on the mic.

Re: Audio Micing Church Choir
 

Small update: Here it is the end of January (within a couple days), and this is still a work in progress. The SD card with all my "B-roll" files have been delivered to the conductor and he recently emailed me that they were copied to his computer, presumably okay because he didn't say there was a problem. Remember, he is running a PC and Vegas and I'm running a Mac and FCPX so there may be issues there.

Tomorrow I will hopefully get the SD card back and, also hopefully, I asked, with his video and/or audio files. He had a Sony cam locked off on a tripod with the H4n recorder on a tall tripod stand behind him. My side of the project has been on hold so we'll see what happens.

Jeremiah: I'm glad to see this thread was of interest. Recording serious audio is a very interesting area and there is definitely a lot to learn about it. For the British audio members here I just found out that some of the girls from this choir were invited to Wales in early July for some kind of choral event. [Note: if I got the terminology incorrect please feel free to provide correction. Choir stuff is not my forte, and, come to think of it, neither is French spelling].

Re: Audio Micing Church Choir
 

The mention of choirs and Wales means Eisteddfod. Choirs are very big in Wales, especially male voice choirs historically led by coal mining communities and are serious stuff. Most are completely amateur but the standards very high. If you Google the word or YouTube it you will hear some fantastic stuff. The US choir will have a great time, and the Welsh love visitors who love music!. My band were invited to a 60s70s festival and the standard of the local contributors we heard was amazing. You don't get this in England or Scotland.

Re: Audio Micing Church Choir
 

Paul - that was interesting. Coal miners, eh? So if one of the guys asks her if she would like to see his digs, I should warn her to look out??? Okay, kidding aside. Just found out her parents and younger sister will be going too and they already have room reservations - and they were hard to get even this early.

It’s interesting how different cultures like certain things. In Austria and Germany, for example, they seem to also be big on group singing. I’ve been to some places where, maybe at a gasthaus, anniversary celebration, or a Stammtish, were everybody would sing songs they know. In Vienna I’ve gone to an accordion Stammtish and one can definitely count on it there. In America, at least on the west coast, it never happens. This particular one there are also guitar harmonica, players.[Stammtisch: informal group meeting]. No conductor although there may be a lead player and the others try to follow. This would be very similar to a jam session but with a difference.

Anyway, for everyone who has been following this thread, I did get the conductor’s video file taken with a small Sony handicam (locked off) but didn’t get the H4n audio file. He says he is really busy and given how long it took to get this far I’m, I'm sorry to report, I'm going to give up because I don’t want to nag him. He is also the conductor that will be taking the choir to Whales so I’m sure he is very busy. I’m going to chalk this up to “lesson learned” and if I do it again I'll take my own laptop along and copy the files right then and there. This long distance stuff just doesn’t work.

I’ll still put some multicam video together (3 cams) but, unfortunately, with very lousy audio, and It’ll be “quick and dirty” for personal and family consumption only. *sigh* On the plus side, it was a very enjoyable event.

My next project will be doing some piano recording - have an upright and a rebuilt (if that's the right word) “golden era” Steinway grand to work with but I’ll start a separate thread on that. The good part is I'll have full control. Just got some key grip-kit bits and pieces in today for the mics and lights, and a few more pieces on the way. Lookin' good. More on this to come.
