I'm doing an interview radio program that is a host and a band around a small roundtable. We are using 3 supercardioid AKG D5. While they work extremely well on eliminating the background noises, it has some downfalls, like having to speak really close to it (the guests always forget), having to pass the mics around when there are too many people talking, a bunch of cables and, the worst one, the intimidating "studio feeling" instead of the "friendly bar chat" that we aim for. I was wondering if a single omni mic fixated on the center of the table could do the trick here. Guests would be ~50-70 cm from the mic. Sound fidelity don't need to be great as it's just spoken word and probably will go to a truckload of compression. I have zero experience with omnidirectional mics. Never had one and never needed one, so I'm clueless here. Do you think this would work? Not sure if the sources are too far away from the mic, or the background noise will be overwhelming after compression.
