2BC multiCORR is a multiband correlation with integral monitor control. Stay on top of correlation, across the spectrum. A multiband correlation meter with essential metering and monitoring functions.
Can You Relate?
Why the heck do you need a multiband correlation meter? It’s simply that a regular stereo correlation meter doesn´t identify specific trouble spots. If your fat kick and bass is mono, it’s mostly correlated so a stereo correlation meter would show that everything is O.K. while your strings, hi–hat, or vocals are cancelling out! 2BC multiCORR combines the useful and beloved functions of our free 2BusControl monitor controller plug–in with a carefully designed, third octave multiband correlation meter. Our multiband approach warns you not to overdo stereo spread with your fancy spreading tool, or when your stereo mics are delivering a signal with too much out–of–phase content. Either way, you’d get cancellation when your mix is summed to mono.
Correlation measures the degree of relatedness between left and right channel. If they’re alike, that’s mono, and they will have perfect correlation. Stereo noise is decorrelated, with no similarity between channels. Stereo music should be more like the former, with a bit of “stereoness” to create a soundstage, whereas convincing, diffuse reverb should have lower inter–channel correlation. When content is present in one channel, and an inverted phase version is in the other channel, that sums to zero in mono and the audio disappears.
2BC multiCORR’s powerful features hide behind its clean and simple UI. We’ve brought essential functionality and innovative user interface design to what used to be an unremarkable product category. With five monitoring modes, an ergonomic and deceptively simple interface, highly tuned correlation metering over thirty one bands plus stereo balance and correlation, you’ve got to try 2BC multiCORR for yourself.
Better By Design
Most correlation meters use a cosine scale, derived from old analog meters, while 2BC multiCORR employs a trueLinear™ scale. This linear scale better matches your perception. As with all of MAAT’s products, 2BCmC follows our guidelines of creating meaningful tools for modern engineers.
2BC multiCORR combines essential metering and monitor controls with a 31 band correlation meter group.
- 31 bands of correlation with carefully chosen center frequencies
- Exclusive trueLinear™ scale for higher precision with visuals that match your perception
- Stereo Balance and Correlation
- Five essential monitor controls: Left–Only, Right–Only, Mono (L+R), Diff (L-R) and Flip
- Collapsable UI lets you see only what you need
Includes a native version that runs in standalone mode, great for dedicated metering
Plug–in runs on all major DAWs: AAX, AU, VST 2 & VST 3
2BC multiCORR is a general purpose tool for both production and post. Use its powerful metering and monitor controls for:
- Tracking and Mixing
- Mastering and Remastering
- Sound & EFX Libraries
- Radio & Television Production & Broadcast
- Identifying Problem Elements; EFX, panning, widening or frequency ranges that may compromise playback or downstream processes
- Verifying: balance, panning, super stereo processing and other creative decisions
2BC multiCORR slots into all modern workflows:
- Supports LPCM sample rates up to 384k for DSD and high–end postproduction
- All standard formats: AU, VST 2 and 3, AAX
- Compatible with macOS and Windows
- Low fatigue visual design
- Resizable user interface for every screen resolution
The Low Down
If your material is destined for LP distribution, keep in mind that lacquer cutting has difficulty with large amplitude, out–of–phase information at very low frequencies. 2BC multiCORR provides four bands of analysis for the critical bottom octave, six additional bands of metering covering frequencies up to 200 Hz, plus three additional band for the 200 to 400 Hz range.
Other than vinyl, why should you care about mono? Monaural playback is more prevalent than ever, with the rise of battery–powered, hand held party speakers and the seemingly ubiquitous “smart speaker.” Don’t forget that Center Channel speaker in a surround setup…Though a product may advertise stereo playback, the simply fact is that size matters. At low frequencies, playback from any single point, diminutive device is essentially monaural. Also, small sources usually cannot reproduce the bottom octave at all and many begin to roll off below 100 Hz. So make sure to maximize the appropriate amount of LF energy for the material you’re working on.
Not Just Correlation
2BC multiCORR isn’t just multiband correlation. It also includes a left/right balance meter, a broadband left/right correlation meter, plus five monitor controls allowing you to focus on any issues you may come across.
With a single button, you can switch to Left–Only or Right–Only, Mono (L+R) or Difference (L-R). The fifth monitor control, FLIP, swaps the left and right channels. Sometimes you may come across a subtle issue that you think may be in one channel or the other. The Flip control, along with the Left–Only/Right–Only buttons, quickly helps to confirm or identify any problems. Also, you may occasionally be presented with a mix that’s not laid out from the audience perspective, and Flip is a quick way to rotate the soundstage around to where you’re comfortable.
For extra versatility, 2BC multiCORR includes a native version you can run anytime to meter outside of your DAW or plug–in host. To use 2BCmC standalone, you will usually need a “virtual audio device,” an audio driver that provides a software “device” the operating system can use for I/O patching. For Windows, we recommend VB-Audio’s VB-CABLE. For macOS, we recommend Existential Audio’s BlackHole. Both are free.
Don’t Hit The Chair Without It!
2BC multiCORR packs the advanced features you need into one resizable window that’s easy on the eyes. Not only does the UI “get out of the way” so you can be more productive, we’ve incorporated user–centric features that speed your workflow. Easy and intuitive to use, be sure to hang it off the last slot in your Master Bus so you always know exactly what’s going on with your mix!
