Yes, but (rolling up sleeve), you can place the phone on a plane such as a foot-square piece of 1/2" plywood over a towel and get the 6dB back in pseudo pressure-zone technique.
good SN ratio is not one of them.
I wondered about that. I was fully expecting to need noise reduction. Imagine my surprise when I passed ACX without it (not by much), and further, it was pink-sh and easily ignored. Even without the Voice That Goes Through SoundProofed Walls, the Noise Reduction of the Beast (6, 6, 6) is a perfectly valid correction and can't be detected after submission.
Join with me and contrast that with the trouble you can get into with a Yeti.
This technique does have its moments. Getting the work from the iPod to a Mac is not for the easily frightened and then converting into WAV has produced several furrowed brows (as well as damaged sound).
As I've already found, a recording will not start until the first sound arrives. I can't wait to find there are conditions when it will stop by itself for no apparent reason. The software is intended as a music note taker—to record moment-by-moment musical ideas. I have no idea how it will react at the prospect of recording a book chapter. I am encouraged that CAF format was designed to have an almost unlimited recording time.
