I am looking at doing some M-S recording for some of the live shows I produce for audience reactions. This isn't dependant on a camera as most of the audio is generally used in podcasting and radio formats.
The plan is that I will use a omni for the mid channel, a figure 8 in the side channel which is fairly standard. Then also mix in wireless handhelds in mono from the presenters that will be wondering around the audience (think about the audience in a circle). The whole thing will be done to a stereo file, not separate channels.
Will having the handhelds directly put into the mix screw up the M-S recording? My logic says no, and the stereo image should be fine and collapse to mono without any issue. Am I missing anything here?
