1. Route the recording from a cardioid microphone to a mixer, pan it dead-centered.
2. Route the recording from a bidirectional microphone to the second channel of a mixer, pan it to the left channel.
3. Copy the recording from a bidirectional microphone to the third channel of a mixer, pan it to the right channel. Invert the phase of this channel (if your host program doesn’t miraculously involve channel inversion, you can find a plugin specially intended for it).
Use of Mid-Side recording
So after we have recorded the sound, we decode it into stereo with the help of a mixer. It’s noteworthy that in the studio of online mixing and mastering services we can manipulate both stereo and mono recordings simultaneously. Due to it you are given broad options, for instance, you can change the width of a stereo base while sound mixing or process a mono bass drum with an equalizer. All of this is possible if you use Mid-Side plugins. Some plugins allow you to process mono and stereo with a de-esser independently. It gives a fairly good result.
Which plugins support Mid-Side technology?
There are a lot of manufacturers which produce plugins to work with Mid-Side recordings which are widely used at mixing and mastering. As for me, I’d mention the German company Brainworx which now produces quite quality Mid-Side processors. Processor Flux: Alchemist is also fairly good.
Another much better known plugin, which supports Mid-Side, is iZotopes intended for composition mastering. This software work you can hear in available on the website demos of professional mixing mastering services.
