Experienced mastering engineers regularly use M/S processing to affect stereo signals in ways that seem almost like magic. By splitting a stereo signal into two parts, the mono, or Mid (M) and the left and right or Side (S), you can use tools like compression, EQ and saturation to make dramatic changes to an already mixed track. With this complete M/S Mastering bundle with products from respected audio companies like elysia, Brainworx, SPL and Dangerous Music, you’ll have everything you need to subtly sculpt or radically repair your masters.

Brand new for version 2.3 is the revolutionary bx_panEQ. This amazing new 3-band EQ, fueled by Brainworx technology, allows you for the first time to be able to choose not only the center frequency and Q when cutting or boosting, but at what point in the stereo panorama you wish to affect as well! Imagine EQ'ing a crash cymbal in a master without affecting instruments panned to other positions in the soundstage. Impossible? Not with bx_panEQ! Its three fully parametric bell curve filters can each be panned anywhere in the mix's stereo field to adjust the timbre of embedded tracks with precision. No other plugin can do that! This plugin is an instant must have for anyone who is serious about mastering.

But the fun with this amazing collection of tools isn’t limited to mastering; these tools can be used on any stereo buss including drums, guitar submixes, backing vocals and more. Individual tracks can also benefit from these powerful and flexible plugins whether they're stereo or mono. Remember that all Plugin Alliance plugins are available as 14-day full function demos and no dongle is required!

List price of the included plugins is $2,520, so you save over 55%!

This bundle can be paid off in 6 easy payments with no interest charged! Just select the financing option on the installment page during the checkout process.

 If you already own one or more of the plugins in this bundle your personal price will be discounted to reflect the plugins you’ve already paid for! If you’re logged into your Plugin Alliance account, the price displayed for this bundle will automatically be discounted. The discount is calculated by adding up the MSRPs of each plugin you already own and then applying the discount percentage for the entire bundle. Easy and fair! Please see our financing FAQ for additional details on how personal pricing and financing work together.
