There are no levels to see on the recorder, so that makes it tough to tell where the clipping is actually occurring.

Okay, I just checked by plugging the mic into my computer and testing it with Audacity - no clipping happened there unless it was right in my face. So I'm going to guess it's the recorder. I'll look into an attenuator pad.

Considering now that the distortion is in the recorder, it grabs my attention that it does so since both devices are the same brand and Olympus more than likely made them to work in a set up like the one you are doing. I would recommend to talk to the Olympus team and see if we are missing something (I didn't find any reference in the manual).

# Preventing audio clipping on inexpensive lapel mics

(Asked by: username_0 on 2013-11-28)

I'm doing some video work on a budget, so I followed a suggestion I found online for audio to combine an inexpensive lavalier mic with a portable voice recorder. In my case, I chose the Olympus ME-15 microphone with the Olympus VN-702PC recorder.

The recorder only has two input volume settings, high and low, and on the lowest setting I'm experiencing frequent clipping when my characters talk, especially when they get excited. Originally we had clipped the mic to the collar of a t-shirt, somewhat off-center, but it also happens when clipped lower on the lapel of a coat.

I'm not concerned about whether the mics are visible, but I'm wondering how to pick up clear sound that isn't louder than the recorder can handle. Would it be better to place it under a layer of clothing? I'm willing to experiment, but I thought it would be helpful to ask others with more experience for suggestions.

What can I do to my microphones to avoid clipping? Can I put them somewhere else? Can I cover them with something?
