52 Reason / Record Tips - Week 41: Mid-Side Processing for Great Masters

posted 2010-12-09 at 11:59

When it comes to mastering, one of the hottest things right now is a technique known as "mid-side processing." As a basic description, mid-side processing uses phase cancellation tricks to isolate the mono information in a mix (bass, vocal, kick drum) from the stereo items (guitars, keys, effects) and then lets you master them separately and recombine them for a very nice sounding master.

This week I brought in two special guests to help me design a mid-side mastering patch for you as well as to help describe the technical intricacies of how this is done. Be sure to visit the links in this video, download the patches, and visit the websites I mention.





Big thanks to Kurt Kurasaki, Giles Reaves, and Southern.

Thanks dude, this is most helpfull than just using Maximizer and Sidechain over compressed dance music track ^^
Now i can work in more acoustic and audiophile way without brick walling and kind of Loudness War.

Great to see these kind of techniques coming to the public!

I thought Thor was a synth?
I see it commonly used for anything else.
Maybe the props should create a Thor-FX module...

Ditto to snaa - I have really enjoyed all of the tips this whole year but the recent series have been SO helpful in getting concise explanations of what in my mind are the things that I know are so important toward a more professional mix but are certainly not things to stumble upon via exploration. Keep 'em coming :)

I found the information in this video is incredibly useful, and it also exposes how powerful this software actually is. It's more proof that reason/record can sound ANY way you want it to - it can sound like a toy, or it can sound like a million bucks.

I made a video about a month ago that has similar principles to the vari-mu concept that peff and james talk about that focuses on the gain reduction out on the m class compressor - check it out:

Just when i tought Reason/Record could do anything...you guys come up with a professionnal technique (wich i knew, but not sure how to do it in Record) and make it accesible.

impressive! (insert Yoda voice here)

Hi, james, thanks for all the tips, i've learn a lot a things here :).

I can suggest you, for a future tips, to explain and show how to replace the usual panning, with a small delay on the right or left channel. And maybe explain the "Haas" effect a little bit.

Happy new year to you, and all the Props guys ;)

The one problem i have here with this one is... What is the benefit to doing Mid-Side Processing? That was kinda not mentioned...
