GOOD PRACTICES TO MAKE A CORRECT SURROUND MIX, TOOLS AND TIPS
WHY DO YOU HAVE TO CONSIDER MASTER YOUR MOVIE IN 5.1 MIX?
A lot of producers and filmmakers mix and master on stereo their creations, usually by the budget, deadlines and other factors. But what happens if your product one day gets 3.000.000 of followers, plays, and a great company wants to distribute your movie in Blue-Ray? Would you like to see your movie with a thin and small focus stereo mix in a cinema or theater? you will have to make a new mix and sound design to produce a surround master, and a new $ budget, and in some cases this is not possible because the original material was deleted or lost.
So consider if your creation could have the possibility to become a Big Seller Product. It is better to have a 5.1 and Stereo master from the beginning increasing the initial budget a little.
BASIC GUIDELINES AS A STARTING POINT FOR CREATING A CORRECT 5.1 MIX:
- Dialogues: 100% Center Monitor (sometimes 20% L/R)
- Foley: 100% Front L/R (but usually panned to phantom center)
- Impact and strong Effects: 100% Front L/R + 50% LFE
- Backgrounds and Ambience: 50% Front L/R, 50% Sides/Rear
- Music Stereo: 75% Front L/R, 25% Sides/Rear
- Music by Stems: 50% Front L/R, 25% Sides, 25% Rear
CALIBRATING YOUR SPEAKERS CORRECTLY
Make sure your monitoring speakers are positioned, angled and calibrated correctly. Take into consideration this important step, or your surround mix will not translate well to other environments.
You have a guideline in this document from NARAS “Recommendations for Surround Sound Production”, which you can find here.
The plugin from Waves M360 Surround Manager will help you for achieving optimum placement, balance, and extension in the studio.
Calibrating the speakers simply means adjusting each speaker volume at the sweet spot, the speakers have the same Sound Pressure Level (SPL). Which SPL to calibrate to depends on the room size. Calibrate your monitors with the reference below. Detailed instructions to calibrate your speakers.
Movie Theatrical release
85dB 85dB 85dB 82dB 82dB 85dB 90dB
Movie DVD release
85dB 85dB 85dB 85dB 85dB 85dB 90dB
78dB 78dB 78dB 78dB 78dB 78dB
85dB 85dB 85dB
Music ( 5.1)
85dB 85dB 85dB 85dB 85dB 85dB 90dB
(In a small studio you can lower to 79/76db SPL)
Usual levels depending on the release:
-20dB/-27LUFS -14dB/-23LUFS (EU) -6dB/-15LUFS
Other measurements and good practices:
Trailer loudness should not exceed 85 dB Leq(m)
Commercial loudness should not exceed 82 dB Leq(m)
MAKE STEREO SOURCES TO MONO TRACKS, WHEREVER POSSIBLE
Creating surround mixes with mono sources is a lot easier, and a lot more effective, than creating one from stereo sources. Consider reducing your beautifully recorded stereo piano down to a mono track before starting your surround mix. Alike for stereo keyboards, backing vocals, guitars, etc. Doing so will allow you to construct a more impressive surround field, with a lot less need for compression, EQ, or other types of processing. This is possible working with stems or splits, when you have finished music stereo tracks we can only use them as stereo in our surround mix.
SURROUND MIXING NEEDS LESS COMPRESSION AND EQ
The new audio engineers when start surround mix work, discover that less compression and EQ is needed. Place elements in the mix on 6 speakers is way better than mix in 2 speakers. All flow easily. With six or more channels in the studio, the music and the rest of components has a lot more opportunity to breathe on its own, and this lets you not to force the mix.
The converse is true as well: If you overcompress in surround, the overall mix becomes bland or congested and difficult to listen to. You’ll find that the “glue” in surround mixes is a lot more subtle than it is when mixing in stereo.
SURROUND MIXING USING HEADPHONES
Nx Virtual Mix Room is a tool for mix your surround project on headphones, it will help you to place elements in the field. Nx Virtual Mix Room works as 7.1, 5.1 and 5.0 surround environments. You can use it as a second reference, apart of your surround monitors, or people out of the studio.
This video shows some of his processes for mixing stereo-recorded music for surround using Nx.
IN SURROUND MIX, USE MULTICHANNEL REVERBS
To create a sense of a better immersion in the room, use a reverb specifically designed for multi-channel applications.
The Waves IR360 Surround Convolution Reverb is a nice tool. It delivers the sampled sound of world-famous venues and includes over 100 impulse responses of spaces and devices, multi-channel convolution reverb with accurate control over early reflection and decay time.
Another good option is the H-Reverb, which lets you shape and adjust the decay envelope beyond the standard linear forms for gated, reverse and others thick reverb tails that don’t muddy up the mix. Other features include pre-delay BPM sync, resonant filter sweeps, and an EQ and dynamics module for compression, ducking and de-easing.
Same with delay effects, Slapper is a multi-tap surround delay with an intuitive interface, great console integration, and some atypical sound design possibility.
Though the results may not be quite as phase-coherent, you can use multiple stereo reverb to create real ambiance, insert 2 aux channels and pan channel 1 to L-R and channel 2 to mid sides or RearL-RearR. On back monitors, use a long reverb with 100 or 200 hundred milliseconds of pre-delay to create a natural decay and no collapse with front speakers. You can insert soft delay plugins to make different effects. Try and tweak.
5.1 MIX, NEVER SEND SIGNALS TO MULTIPLE SPEAKERS WITH SIMILAR LEVEL
One thing that will harm your surround mix is to send signals to multiple channels, especially neighboring channels such as the center, front L, and front R monitors, at the same level. Doing so will almost always result in some frequency components canceling out, resulting in comb filtering and a very evident “hole” in your mix, particularly as you move your head around.
If you’re going to send a signal to multiple channels, do it at different levels (75% and 25%) or delay the signals slightly – optimally somewhere between 12 and 48 milliseconds. The human brain registers this as natural reflections, just like in a real space, and comb filtering will be at least minimized, if not completely eliminated.
DIFFERENCE BETWEEN CENTER CHANNEL SPEAKER AND A PHANTOM CENTER IN STEREO SPEAKERS
The experience in stereo mixing has trained us that the way to get a signal to appear straight in front of us is to route it at the same level to the left and right channels, so this will create a phantom center image.
This method works when we mix in surround, but the difference is that you now have an unobtrusive center channel feeding a real monitor physically located between the front L and front R monitors.
So what’s the best way to pan center?
One factor to bear in mind is that the center channel speaker in many home systems, particularly “home cinemas” ones, can be totally different from the other speakers due to space considerations and may even be voiced for speech rather than music. In such cases, the sound coming from a real center speaker exhibits a soft midrange bump as compared to a sound appearing from a phantom center, a phenomenon that can tend to make vocals rather harsh.
There is as well a natural problem when we pan with a phantom center, in that it only works for listeners near the listening position; a viewer seated around the left monitor, for example, will hear the signal as coming from that monitor alone. So if that viewer moves around the theater, the signal appearing from the physical center channel will remain fixed, while the phantom center signal would shift, skewing the soundstage. For that reason, dialogues usually are placed in the center channel. Sometimes phantom center in used to create a different voicing effect, for example with a specific actor.
