Nikon Coolpix P7000 External Mic Test

To test the Nikon Coolpix P7000 sound in videos using internal vs. external mics, I sat in a wagon in our garage while my son rode his bicycle around me. There may be some background noise of cars passing by on the street outside.

This first file is a 256Kbps MP3 converted from the video I shot with only the built-in mics.

The following is a 256 Kbps MP3 converted from a video shot moments later from exactly the same spot, with my Core Sound Low-Cost Binaural Microphones attached. No pre-amp nor any separate power source was used (these mics draw power from the recording device). The left mic was clipped to my glasses directly in front of my left ear, and the right mic in the same spot on the right side of my head.

Notice more background noise with the external mics (something I do not normally get with these mics at all). I suppose a powered mic arrangement might eliminate some of this. Not sure.

For comparison, listen to a sample from the same mics using my voice recorder (which records at a paltry 128Kbps wma), which features only two levels of recording sensitivity: dictation and conference. This was recorded in dictation (low) sensitivity mode, and I suspect that the P7000’s default setting is more like the recorder’s conference sensitivity mode. Alas, on the P7000 we have no audio level control at all.

  1. It would have been interesting to here a conversation like in the third example in the others as well.
    Then, as you seem to be engaged in voice recording, your valuation of the P7000 sound quality would be interesting.

  2. Eberhard — Agreed, but in a hurry I could not find recordings from the camera and the voice recorder that compared more closely. I mainly wanted to point out the lack of hiss or other noise introduced by auto-gain. The P7000, admittedly, was trying to crank up the gain because for much of the early part of the recording there was barely any sound. Plus, it was in a garage — not a very good environment for accurate binaural recordings.
