[QLab] Multi channel files

[droy...@techie.com]

Ok I'm sure this is a very silly question...

I'm interested in mixing down multi channel files to playback in Qlab.
Up to now I've only made mono or stereo files. My question is 2-fold:

1. Can anyone point me to instructions on how to actually mix down
files that have greater than 2 channels? I've never done this and have
no idea how. I normally use Pro Tools 8 to edit audio, although I've
recently started working with Ableton.

2. Any recommendations for final settings of files? Sample Rate/Bit
Depth etc? Any issues I should be aware of intermixing stereo or mono
files with multi channel files in the same show? Should I worry more
about processor speed/RAM/Disk Speed for reliable playback?

Thanks

Hi David,

Just do it in QLab. :) Drop in the file and use the crosspoints to
mix the multiple channels to your stereo outputs.

Best,
Chris

Should rephrase...

I'm interested in creating the multichannel files - and then utilizing
the crosspoints to assign channels to multiple outputs. Up to now I've
been mixing down to a stereo interleaved file in my editor (Pro Tools),
and then playing the stereo file in QLAB. In order to create surround
effects in QLAB I create several stereo files in Pro Tools, then with
the help of cross points and fade cues I create a sequence in qlab that
routes the appropriate channel to the appropriate speaker, and if
necessary moves it to another speaker. For example File #2 L is routed
to a Rear L speaker, while File #1 R is routed to Front R speaker.

I'd like to do more of this work externally in Pro Tools (or whatever
people think is appropriate - I'm open to switching editors) and then
creating a file with greater than 2 channels to use in Qlab. I just
don't know where to start learning how to do this. I'm perfectly
willing to sit and read and teach myself how - I'm just looking for
some advice to get me pointed in the right direction. I guess what I'm
saying is in Pro tools I have a session with 14 tracks - and I'd like
to be able to save a 14 track file. How to?

I'm not sure if Ableton will make you a multichannel file, PT8 will make surround files (5 discreet channels).  You may want to use the panner to isolate an element to a channel.  Say Guitar to L, Bass to C, Keys to R, and Drums stereo to Left and Rear Surround.  Use the panner to put the mono files into just that output. 

I've also had good luck making stems and merging them using SoundFilesMerger, a little freeware utility. 

2. Any recommendations for final settings of files? Sample Rate/Bit Depth etc?  Any issues I should be aware of intermixing stereo or mono files with multi channel files in the same show?  Should I worry more about processor speed/RAM/Disk Speed for reliable playback?

Using the internal drive in a stock mac MINI i never had any trouble running 2 or 3 8 channel 44.1 16 bit files along side a couple of stereo files.  Be warned that they do eat disk space really very fast.

I hope that helps.

Logic Audio also has a surround sound panner and the ability to render
the project down to a multi channel WAV file.

So specifically you want a DAW with surround sound capabilities such
as:

Nuendo
Cubase 5 (not Studio or Essential)
ProTools (not LE)
Logic Pro as part of Logic Studio (not Logic Express)
Digital Performer

You may want to move the sound sources around the field using automation
tracks controlling the surround sound panners.

Then you render the entire project to a multichannel wav file and feed
the file to QLab.

Pro Tools HD or Pro Tools LE with the Complete Production Kit can
export audio with up to 8 channels in a single file, but there is
something tricky about not being able to specify the order of the
channels - so channel 2 will always be C, for example (see p983 of the
manual). Pro Tools LE or M-Powered can only work with stereo.

Audacity can merge multiple files into one multi-track file (as I
learnt here: http://figure53.com/wiki/index.php?title=Hints_and_tips#Creating_multi-channel_sound_files_in_Audacity)
.

Similarly, QuickTime Pro, Sample Manager and Twisted Wave (and no
doubt a host of others) can do this too. I've got a feeling that Live
is decidedly stereo; I think Logic works like PT HD (but you get to
choose the channel order).

Just to throw another curveball at you, other than actual recorded
surround ambiances, I find most people going to fewer tracks...using
mono spot effects, and constructing the surround environment
completely in QLab, rather than ever letting them mix together in the
DAW. It's a lot more flexible once you get used to the concept. And
with the waveform view in QLab 2, it's even easier, with even less
needing to be done pre-production.

Just a thought to think about...

That's very interesting to hear actually. I've found myself using more and
more multi-channel audio files in my shows so I'm kind of surprised to hear
the opposite. Although I'm not usually using the multi-channel file
features to prebuild large cues, I've never really seen that as the reason
this type of feature can be handy. Instead I use it A LOT so I don't have
to go back to the DAW to make a change. If I'm building a cue that will
need reverb or any kind of "effects" really, I might go ahead and try 3 or 4
or more different settings of those effects, plus a dry signal. Then render
a single multi-channel .wav file with multiple stereo or mono versions of
essentially the same sound. This way when I get into the theatre I can dial
in the verb as I like in the space and I'll have multiple options without
the need to open an editor. I can even route the dry signal to some
speakers and different reverbs to different speakers if I like that. For
example I might build a cue with the dry signal on tracks 1 and 2, a very
light reverb on 3 and 4, a heavy verb on 5 and 6 and on 7 and 8 a reverb so
heavy it's more like what I would call "a wash". In the space I might end
up only using 4 or even 2 of those channels as I see fit. Is it a waste of
hard drive space? Sure. Does it mean that I'm streaming a bunch of audio
that is essentially not going anyway, yes. But most machines have plenty of
excess processing power now days unless you're doing a VERY heavy playback
show. (assuming you're doing only audio on the computer... NOT video!) And
hard disc space is cheap.

I will do similar things when I need to make the cliché' crickets or rain or
whatever generic ambiance cue you might need to build. I might pull 3 or 4
or more different rain samples, extend the file out for the length needed
for the cue, and then render that to a multi-channel .wav file that I can
then mix to taste in the theatre. You can then take what might be a rather
boring ambiance cue and play with it over time, just by fading in and out
various tracks or doing really slow, subtle movement of the tracks in the
space.

I think it gives you a lot of options in the space without having to link
together lots of separate playback cues and if there is some timing info
that is important between the tracks, it keeps them all together. It also
means that I can put all the samples and source material into a single
"project" file in my DAW, and then I can hear how all the various "parts"
might sound together but not confining me to create a mix down before I'm in
the space. I find that is very helpful to me when building long running
background ambiances. I like to hear all the tracks and how they blend
together when I'm "building" the cue in my DAW, so I know ahead of time if
something is going to "pop" a lot more than I expect, or if something is
going to get "masked" when listening at the low levels we typically have to
play these types of cues back at.

I don't know, for me and my brain it saves a lot of precious tech time in
the venue which there is never enough of. At least where I get to work
anyway. :-)

I think the main reason I started doing a lot of this is because my DAW
(Sony Vegas and to a lesser extent Sound Forge ) made it so easy to create
these that is just made sense to do it that way. I guess if I had to jump
through a bunch of hoops (like take an extra step of rendering multiple
files, only to use yet another application to interleave them) to create the
files, I would probably just skip that step, and throw the individual stereo
or mono files into the playback computer, which is what I had been doing for
years anyway. :-)

And I will throw into the mix ABShowMaker (Mac software...) which has the
built-in capability of creating single and/or multi-channel sound diffusions
where you draw your 'spacemap' (to borrow a term) and then create your
trajectories and it automatically creates a complex cue that includes the
correct time and level changes to make the sound(s) move or appear to move where
you want them to.

This is essentially a poor person's LCS and it previously worked only with the
AudioBox AB64 but it will soon run with SoundMan-Server. Actually, we are
inviting users to become beta testers as soon as we are ready to move to this
stage. This is the software that I was hoping would be able to be integrated
with QLab and still might be at some point.... Please contact me off list about
testing.

Both great ideas, and ones that I use as well.

I find for certain things when I know a moment of an effect isn't going
to change it's easier for me to create the effect in the DAW. Other
times it's easier to create the effect in QLAB, especially when I know
I need flexibility in tech.

I also enjoy making multiple files of varying reverb or eq. Lately
I've been experimenting with making several channels of a mono signal
that have crossover points - so that I can fade up or down one section
of the frequency spectrum in a cue in the show. Great fun, and with
multiple channel files I'll be able to do it without launching 6 stereo
audio files at once. That method was tedious, to say the least.

Very cool idea, and one I hadn't ever thought of! The trend I've been
seeing lately, as far as verb goes, is to dedicate an output (or a
pair) to one or more outboard verb units, and then return that to the
console along with the dry playback outputs, and do it all live, with
program changes to the units and the playback software doing the wet
dry mix via send levels.

I never get budgets for nice effects units, only what's built into the
Yamaha digital desks, and their verbs leave A LOT to be desired. So I've
always done verbs on cues as either multi-channel .wav files or multiple
.wav files that I link together.

Altiverb, Waves RenVerb, Waves IR-1 all come in AU varieties that QLab
will (hopefully!) support in the future and are all very nice.
Logic's Space Designer is supposed to be very nice as well, but
apparently only runs under Logic, even though it's an AU plug. TC
Elec makes a nice reverb plug-in, but I think it only runs under TDM.

There's some seriously good plugs out there, and getting better all
the time.

Just for clarification, all of the plug in effects and instruments
that come with Logic, including Space Designer, aren't AU plugs, but
rather are built into the framework of the program. None of these plug-
ins can be accessed or used with any other program or DAW except Logic.

On a personal note, I have found Logic's built in effects and
instruments invaluable for my sound designs, and Space Designer
itself, which I use on almost every sound to some degree, worth the
price of the whole package. SD is a convolution reverb plug-in that
sounds VERY nice, and it comes with hundreds of Impulse Responses. Or
you can record your own IR's with the Impulse Response Utility that's
included with Logic Studio, if you're into that. Hope this helps!

Best,
Mark V.

[Sean Dougall]

Actually, if you're willing to get down and nerdy, you can work around
that using Soundflower (http://www.cycling74.com/products/
soundflower), like so:

1) In Audio/MIDI Setup, create an aggregate device incorporating
Soundflower and the physical output you want to use
2) Patch a QLab cue's outputs into Soundflower
3) In Logic:
a) Select the aggregate device under Audio Settings
b) Add an aux channel strip (or an audio track with input monitoring
on), using two of the Soundflower channels for input and two of the
physical channels for output
c) Throw down some plugins

So the routing goes QLab > Soundflower > Logic > physical outputs.
It's not the most flexible setup ever, but it gives you up to 18
channels of effects bussing. I can attest to this working in stereo,
and I imagine it would work for some surround setups as well.

You can build a Mainstage (part of the Logic Studio pkge)  program to use these plugins as part of a live show via QLAB. Using the Metric Halo interfaces makes integration of AU plugs pretty easy with QLAB because you have 18 streams in and out to work with and you can matrix them in QLAB or in the Metric Halo Console software (or both).

i.e. 

If you had a 4 channel source from QLAB. I send QLAB's outputs to DAW1-DAW4 on the MIO (MH Interface), These might be routed to L, R, Lr, Rr via a bus in the MIOConsole software.

I also send a direct out on each channel strip within the MIO to Mainstage via the FW cable. There I can add reverb or any other Logic or AU plugin, send these back to the MIO on DAW5-8, and mix those channels using additional MIO channel strips assigned to the corresponding L, R, Lr, Rr.

Since the MIO does all its mixing in hardware and the fader for each channel can be automated using Pitchwheel command as well as mutes on and off from QLAB MIDI cues, you retain full automation and routing control within QLAB. 

By the way you can also use QLAB to change patches in Mainstage.

All of this can done with 1 firewire cable, 1 Mac and a MIO. Since the MIO is also doing crossover and delay duty, it makes for a very compact and reliable system.

By a strange coincidence I was setting up our RME Fireface 800s today
and discovered that you can do much the same thing with them. I then
wondered if there were any free AU hosts out there and came across
Apple's own AU Lab: part of the Developer tools installed if you run
the Xcode installer on the Mac OS X disc. It's a bit like an ugly
version of MainStage, only free.

What's more, with Soundflower you don't even need an interface that
has a built-in matrix - and with Soundflowerbed you don't necessarily
need any aggregate devices. I now have a MIDI-controllable mixer
running alongside QLab hosting AU plug-ins. I wonder how stable it is?

I've heard nothing but warnings about the fact that it is purely for
testing purposes, and not remotely close to stable enough to use in a
production environment. Caveat emptor.

Soundflowerbed is nice and stable, but adds a fair bit of latency and can be processor hungry if you do matrixing in it (crosspoints seem to be expensive things for DSP).

Beware AU lab, it isn't stable enough to be in a show.  Logic's mainstage is a good option, as are Max/MSP or PD (which is free).  Max and PD both require some work and are happier with VST plugs, but that still offers a plethora of options.

If you're using the Metric Halo stuff, you do have a nice reverb that can be run in the interface's DSP, and EQ/Delay as well, with Q-lab taking fader throws it makes for a fantastic little console for foley mics.

Nice one Sean! My fav is Altiverb.
I'll have to give this a shot and see if I can get it working with
some of Altiverb's multichannel impulses.

Great discussion guys!

Oh, that's a shame. I wonder what Apple's intended purpose for it is:
how can a tool that is itself unstable be used to test other tools?

Out of curiosity, I'd like to know a bit more about that; can you
point me towards some websites?
