To solve this problem, first sum all the channels together so you can see everything in the same window and treat problems globally. A great example of a multichannel audio issue is bows hitting the strings a bit too hard, so that the sound reverberates across the rest of the microphones. RX 7 supports up to 7.1.2 multichannel files, so if you’re editing a live recording for a DVD or preparing a surround mix for CD, you can use all your favorite modules to treat multichannel recordings. With Music Rebalance, you don’t need the multitracks to solve those problems because we can shift and balance different elements of the mix like percussion, bass, and vocals right from the audio file. Lets say you need to remaster song for today’s market but you don’t have the multitracks to work with, and you’d like to bring up the vocals and turn down the percussion. This mode requires longer processing times than the other two modes. Advanced Joint Channel mode offers the highest quality separation results, especially when processing files of high sampling rates or when processing musical content that was not tuned to an A440 scale. Joint Channel mode offers higher quality separation results than Channel Independent mode, especially when processing stereo files with similar content on both channels (correlated signals, strong stereo image). When the second mode is selected, joint channel processing is applied to the input audio before determining mix element separation. The first of three algorithms offers the most efficient real-time preview performance and processing speeds when working with the Music Rebalance module in the RX Audio Editor. Going the other way means the opposite, fewer chances of artifacts, but more potential for bleed. The resulting signal will contain less audible “bleed” from the other mix elements at the cost of introducing artifacts and reduced vocal clarity. Negative values will instruct the separation algorithm to narrowly define what it considers to be vocal content in the input signal. The sensitivity meters in Music Rebalance determine how much of the input signal will be identified as voice by the separation algorithm.

RX 7 also features Music Rebalance, a powerful tool that intelligently identifies vocals, bass, percussion, and other instruments in a mix and allows you to rebalance the gain of each.
