Forum Question: Stereo Lapel Microphone for Recording In iMovie 11

I am looking for a stereo lavaliere microphone for iMac to record voice over. I have background music which is already stereo. Do you recommend any stereo microphone that works with iMac and iMovie 11

    I’ve used the Audio-Technica ATR-35S as a lavaliere many times. You just need a USB interface for it, like the iMic.
    But it isn’t stereo. Most (all?) lavaliere mics are mono, I think. For recording a single voice, I’m not sure it makes any sense to try to use stereo. Think about it — one voice would come from a single point, not left and right. Maybe an audio engineer can chime in on that, but I can’t see the logic to recording one point of sound in stereo.

    Is there a simpler way to make the sound come through the center speaker so that we don’t have to copy it to audocity or Garageband to convert to stereo. The mano-mike comes though only the left channel which is weak and not as good as the built-in mike in iMac 27. I am referring to the voice over, which we may have to change if the message or the content changes. If Garageband can record the audio coming from the same mike in two channels, I don’t understand why iMovie won’t copy it to both channels?

      That’s an iMovie question more than a microphone question. There are stereo lav mics, but, as Gary said, your goal is a single source coming from both sides. The key is that source be identical- something that can be very hard with a stereo mic.

      Small head movements in your head will change the position of the two mic channels relative to your mouth and those phase issues will affect your final audio.

      You just want to double up your mono audio in both thacks in iMovie. Sometjing that should be relatively simple, but which I can’t answer as I haven’t used iMovie.

        Ah, I see. That old problem. A couple of ways to handle that both technical.
        The problem is that the recording is going on in stereo, with only one channel live, the other empty. So you either need to record in mono or export your final project in mono.
        I don’t recall the solution for the first, but you may want to play with the Audio/MIDI setup (Mac app in your Utilities folder) for that mic and see if you can’t get it to behave properly.
        For the second, you simply need to export from iMovie with custom QuickTime settings. Then change the audio settings from Stereo to Mono which will force it to combine the two channels into one and solve your problem.

          The ATR-35 is a monaural microphone that, when recording in stereo, will produce a signal only on the left audio channel. You can purchase an inexpensive (about $4) Mono-to-Stereo adapter from Radio Shack that duplicates the output from the ATR-35 to both the left and right channels.
