Why do you need a multiband correlation meter? Broadband meters don't always show you potential trouble areas. MAAT's multiband approach warns you not to overdo stereo spread, or when your stereo room mics are delivering 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 both channels are alike, that's mono, and they will have perfect 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.

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 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.

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 prospective, and Flip is a quick way to rotate the soundstage around to where you're comfortable.

Most correlation meters use a cosine scale, derived from old analog meters, while 2BC multiCORR employs a trueLinear scale. A linear scale better matches your perception.

2BC multiCORR combines essential metering and monitor controls with a 31 band correlation meter group.
