Upsamplers, DACs, jitter, shakes and analogue withdrawals, this is it.

don't record hot in digital

With analog, clipping is generally soft the first few dBs and gets progressively harsh as you get past the saturation point. In digital, there is no "gray area" saturation point -- only hard and nasty clipping after the "bit bucket" is full.

However, the fact is that some DACs process the signal in such a way that it is best that they not be fed a signal hotter than -3dB. At that point, it seems they will reach 0dB internally and a recorded signal above the -3dB point actually causes problems for the D-A converter. This applies to PCM. For DSD recording, I believe the max signal recorded should be no higher than -6dB (due to a similar reason).

There is a discussion at computeraudiophile.com (a few recording people contributed in the thread -- Barry Diament, Cookie Marenco and maybe a few others) re: the subject of recording levels in digital. Somewhere here at AA, I believe it was Christine Tham -- a few years ago -- brought up this subject because she was hearing what sounded like clipping from some of her discs, yet they were not "clipped" in the recording: they were (just) below 0dB.

I'm sure a search here and there will bring up relevant info.
