I tend to be overly-cautious and not terribly prone to experimentation; but here I suppose that the expenditure of an hour in setup and experimentation on a track or two is in order. Numerous authoritative sources warn of the dastardly effects of over-range when using a digital recorder; this is one reason for a general shift to 24-bit recorders over the past five years or so -- with a dynamic range of 24 bits, adjustment of the recording gain becomes rather non-critical, because the dynamic range of music can be captured accurately with less than 16 bits. So I do not expect to discover that there is a good (much less, easy) remedy (such as scaling the entire recording) for a recording which has been made with the gain set too high. Rather, I expect to find that when a 16-bit recorder receives a peak for which 16 bits is inadequate, the samples in the neighbourhood of the peak somehow are not recorded properly, with the result that the sound is irreparably "scrubbled".
