Slightly basic for this group, but also slightly audiophool, so I figured I'd ask here anyway.
I've got an electret lapel mic that I'm using with my smart phone for making videos. It's pretty good, but it's hot enough that the audio bars on the phone are showing red on audio peaks. I'd like to try toning it down in electric-land so that things aren't clipped going into the phone.
So -- is there a way to attenuate the audio coming out of an electret in a way that doesn't appreciably cut power to the microphone, while retaining the audio quality (which I like)?
I suppose I could make a little battery-powered box that completely isolates innies and outies, but at this point I'd be MUCH happier if the job could be done satisfactorily with some network of resistors and caps, with one variable element to change the volume -- or even a fixed network, since I just want to get things into the phone's happy range and plan on adjusting things more in the video editor.
