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 mixing service 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.
