Re: Uni-directional Microphones

Steve Jacobson

Thank you to all who have responded. Perhaps I should have given more context to my questions. In my mind, the best situation to record a meeting is when one can access the sound system directly as somebody mentioned. Ideally, one would have their own separate microphone to mix with the input from the sound system to pick up questions from the audience. If one can't access the sound system, attaching a small microphone directly to the stand that holds the sound system's microphone has often been a good strategy. However, recent trends can make this kind of arrangement harder to achieve. For one thing, often there is no microphone stand with a main microphone, being replaced by wireless microphones. Sometimes, sound systems are all contained within a single cabinet along with the speaker and it may be brought into the meeting room just before the meeting starts. I have found that sometimes, just placing a microphone on the table at which speakers are sitting can work well, but sometimes that arrangement picks up a good bit of room echo from the sound system itself. In that situation, a cardioide pattern would probably help. I have just been trying to think of other methods that might work as alternatives in difficult situations. Although we would never have considered this years back, picking up the audio from the speaker can be a reasonably good approach with a good microphone and a full range speaker as somebody else suggested. While I am familiar with cardioide patterns, I have never had any experience with a shot gun type of microphone. I understand older designs were fairly long and don't know if there are newer designs that might achieve some success with electronic noise cancelling technologies, which is the reason for my questions. Clearly, if one were to use a shot gun style of microphone, one would have to monitor continuously, as Tim suggests.

Best regards,

Steve Jacobson

I would not recommend a figure 8 pattern if you are sitting in the
audience and want to record the people on stage. A firugre eight
microphone picks up equally from the front and the back of the mic, so
it would pick up the audience as well as the people on stage. You
probably want a pair  of cardioid or shotgun microphones.

A pair of Matched SE-7s should do. I was going to ask if it had to be
dynamic or condencer but he says he'll be in the audiance so that
means he's pretty far. No not realy but I'm not sure how far dynamics
hear. So SE-7s would do. They're only $199 for a stereo matched pair.

give the best results but there is going to be some handling noise.
Unless the mics are very expensive.

The common terms are omni-directional and figure 8 polar patterns
that may meet the criteria as expressed.

The choice of microphone depends upon the quality desired and the
money available. In addition to the event’s structure and location. 
If all participants are co-operative.

Hi, Steve.
It depends what type of microphone you are talking about. If you
mean a standard cardioid microphone, that might work fairly well. If
you meansomething that is even more directional, like a shotgun
microphone, it might be difficult if there are multiple speakers on
the stage, since you would have to move the microphone back and
forth to capture the audio from all the speakers.
Also in this particular situation I would advise that you use
headphones to insure you are getting the best possible recording.

Does anybody have experience with using a uni-directional
microphone to record a presenter at a meeting from the audience?  I
know there are directional microphones that work well to allow a
speaker to be picked up at a close range while suppressing
feedback, for example, but I am interested in being able to better
pick up a speaker from, say, the first row in the audience.  Any
thoughts on what degree this is practical would also be of interest.
