Converting a Mix to Surround in DP3



Welcome to the first installment of a new monthly feature in Keyboard: Computer Recording. Rather than providing generic tips that can be used with various kinds of software and hardware (as in our popular Studio Sense department), each month this column will focus on how to do a specific task on one of the Big Five sequencer/recorder applications -- Cakewalk Pro Audio/Sonar, Digidesign Pro Tools, Emagic Logic Audio, Mark of the

To provide the most authoritative, up-to-the-minute information, we'll often be publishing columns penned by the manufacturers themselves. But rest assured, Computer Recording is not about hyping these products: It's about helping you make better recordings. This month, MOTU's Jim Cooper leads off with a discussion of surround mixing in the just-released Digital Performer 3.

By now, you've probably already installed your Digital Performer 3.0 (DP3) upgrade (or you soon will). When you launch DP3, you now have at your fingertips a complete audio sequencing surround production environment. And since surround is the Next Big Thing, it's time to dive in. Surround is not just for movie and game soundtracks; the DVD-A (audio-only DVD disc) format is now gaining speed. Before long, your clients and listeners are going to be asking you for surround versions of your music tracks.

DP3 makes it surprisingly easy to ''go surround.'' In this column, we'll take you through the process of transforming one of your existing DP projects, a multitrack music mix, into a surround mix, complete with live input from virtual instruments. Once your studio is equipped for surround, doing surround mixes is easy and fun. If you're like me, you'll be truly inspired by the creative possibilities.

The first step, and the most involved by far, is to set up and calibrate your surround speakers (as described on page 670 in the DP3 User Guide). With DP3's speaker calibration plug-in, you have everything you need to accomplish this. You don't necessarily have to buy a matched set of five speakers, although if you can, you should. Another option is to purchase a headphone surround monitoring solution such as the Lake Technologies TheaterPhone HSM6240 (www.theaterphone.com), which provides 5.1 surround monitoring via your current standard pair of headphones.

Converting an existing mix to surround

Open any existing DP project. For the purposes of this tutorial, choose one with standard rhythm section/bed/lead instrumentation: drums, bass, rhythm guitar (or keys), keyboard or string bed, plus vocals or other lead instrument. Or you can use the demo project on the DP3 installer CD (copy it to your hard drive first).

Open the Audio Bundles window (Windows menu). Click the Outputs tab. The output bundles you currently see in the list will all be mono or stereo, depending on the project. Now it's time to create a surround output bundle. Click the Add button and a new output bundle appears at the bottom of the list. Choose ''5.1'' from its Model menu and rename it if you wish. (You don't need to include ''5.1'' in the name, as DP3 automatically appends the channel format to the name.) If necessary, rearrange the chicklets to assign each channel to the appropriate output on your audio interface.

When you're done, your Audio Bundles window should look something likeFigure 1. InFigure 1, the audio outputs used for surround are analog outputs 1-6. In a similar fashion, create new stereo bundles whose outputs match the L/R (Left/Right) and Ls/Rs (left surround/right surround) speakers of the 5.1 bundle. Depending on the material you're mixing, you might want to create one mono bundle each for the center channel and the LFE (Low Frequence Effects) channel. These mono and stereo bundles let you route tracks to specific outputs within the surround matrix (such as L/R) without having to fiddle with a surround panner.

Now you're ready to convert your mix to these surround outputs. We'll use them as we go along, but first it's a good idea to set up master faders. Create a master fader for the 5.1, L/R and Ls/Rs bundles, and assign each master fader to the corresponding new output bundle.

Turn your studio mix into a live concert

One interesting application for surround mixing is to convert a studio mix into a ''live concert'' mix, reproducing the ambience of a performance venue, complete with crowd noise. Ever wonder how your studio mix would sound in an amphitheater? Now you can easily find out!

When mixing in surround, one approach is to recreate the placement of instruments as they were (or would be) placed in an actual space. For example, the listener could be placed in the position of an orchestra conductor with the instrument sections positioned relative to the conductor.

For our basic mix, you can employ this approach by placing the band ''onstage'' using the three front speakers (L, C, R), and the room ambience and crowd noise toward the rear (Ls, Rs). Here's how you can accomplish this convincingly with the stock effects included with DP3.

Set up two stereo aux tracks. Put eVerb on one of them and DP3's stereo delay on the other. Choose a desired reverb preset

p.112




(such as ''Hall with Drapes'') that matches the size venue you'd like to emulate, and choose a delay preset (such as ''Stereo Slap-slap'') that emulates a corresponding amount of acoustic slapback. The reverb and delay coming from the rear surround speakers generate a sense of space. For both aux tracks, assign their output to your Ls/Rs stereo bundle. For their input, you'll use buses.

In the Audio Bundles window, click the Buses tab, create four mono bus bundles, and name them eVerb.L, eVerb.R, Delay.L, and Delay.R. (If all your tracks are mono, you can create just two mono buses.) Also create two corresponding stereo buses (eVerb and Delay) using the same pairs of buses, as shown inFigure 2. Then choose each stereo bus as the input of the eVerb and Delay aux tracks, respectively. That's it for setup. Now comes the creative part.

Surround drums

If your project has a stereo drum mix (instead of individual drum instruments), assign it to the 5.1 surround bundle, open the Arc Panner plug-in for the track, choose Balance stereo mode, and push the panner puck somewhat

Set the Focus control to somewhere in the middle to bring in the center channel, if desired.

Use the expand triangle to view individual channels levels and even mute and solo individual channels to check the front-to-rear balance. If it's a stereo drum track, use all four sends to bus the stereo drums to the reverb and delay aux tracks (using the buses you set up earlier). Use the send level (option-drag for stereo send pairs) to apply just a little bit of reverb and delay. If individual elements of the kit are on separate tracks, try applying a little more delay to the kick, snare, and toms while backing off slightly on other elements (hat, cymbals, etc.)

Other elements

Try assigning bass to the L/R stereo bundle and use the same bus/aux track technique discussed above to apply Ls/Rs slapback to the bass. You'll probably get best results on the bass with delay only, but you can certainly try reverb. For rhythm elements such as rhythm guitar or keys, try delay only, or delay with just a bit of reverb. For lead and bed elements, try more verb, less delay.

Keep the effects you're applying subtle. If you apply too much reverb, it will just sound like reverb instead of spaciousness or ambience. If there's too much slapback, it won't sound natural.

Crowd noise

Obtain mono or stereo crowd noise samples (or go to www.motu.com/freecrowdsamples). Get ''nearby'' sounds (individual handclaps, etc.), along with more general crowd ambience. Drop

these audio samples, looping them with crossfades if necessary, in separate tracks and assign them to the 5.1 bundle. Apply Digital Performer's Auralizer panner to both tracks. Place the pan control straight back from center (the crowd is around the listener, not up onstage). For the nearby sounds, choose a smaller room size and volume; for the larger crowd ambience, choose a larger room and volume. By combining these two ambiences, you'll generate a sense of depth.

Since the samples probably have inherent reverb, it won't be necessary to bus them to eVerb the way you did for the instrument tracks. For an even more realistic experience, add applause tracks for the ends of solos and the like (with volume automation), as well as the beginning and end of the song.

A/B-ing with the original mix

For a reality check of your new surround mix, try A/B-ing it with the original stereo mix. If you don't already have a stereo bounce of your original mix, use Bounce to Disk to make one, then use solo mode to A/B the stereo mix track with the rest of the surround

You can do this on the fly, of course. This should give you a good sense of the atmosphere you've created. It will also help you get a better sense of how subtle you can be to achieve a convincing result.

Other surround mixing techniques

So much for our live concert surround mix. But what if you just want to go surround, without the live concert feel? Where the heck do you place the instruments? Two general schools of thought have emerged: (1) the ''natural/ambient'' approach, where most of the instrumentation is placed in front, and (2) the ''middle-of-the-band'' approach, where the listener is surrounded on all sides by instruments. When you add panning automation to move instruments and sounds around the listener, the possibilities are endless.

As long as you adhere to the general principles of good mixing, such as clarity and balance, my advice is to go for it: Experiment like crazy and make up your own rules. Ultimately, what you do may largely depend on the material you are mixing and your goals for the mix.
