today I took part of workshop about microphones and mastering Mid-Side technique with a special speaker Andy Eschenwecker, designer and chairman of Vertigo Sound.
In the morning he explained about stereo microphone technique and he compared coincident (A-B) and no-coincident microphone array (XY and M/S) regard mono compatibility and critically ambience. He explored the connection between stereo wide and microphone levels, or polar pattern of Mid microphone, into Mid-Side technique.
In the afternoon he showed his gears: VSC-2 compressor on single track or group or mixbus and VSM-2 MS extension on stereo tracks.
