Old Nabble - SoX - Normalizing to dB FS: "Without additional parameters, SoX's `norm' effect *does* normalize to 0dB FS. By convention, in digital audio, normalize means to amplify the audio such that the peak level is at a particular level; almost always, it is 0dB FS -- it cannot be higher; sometimes it might be a few dB lower than 0.
