I was wondering if downgrading, with sox, material with 24-bit and 192kHz samplerate, to 16-bit and 44.1kHz samplerate hurts a lot.
Not that I have noticed anything, but is this a dirty technical procedure?

Of course we don't listen with our eyes, but the differences between sample rate converters are demonstrated visually at http://src.infinitewave.ca/ ... There you will find that SoX is among the best, at least when converting from 96 kHz to 44.1, which is all they tested. (Generally I would say that any bright non-purple lines on the lower two-thirds of the graph, or to the right of the main peak, indicate a risk of audible problems in actual music.)

When ripping with peaks near 0 dBFS, vinyl's noise floor (the sound of vinyl rushing past the stylus in an empty groove) is around -50 to -60 dBFS, which is in the 10-bit range, so I highly doubt reducing from 24 to 16 bits ever could make a difference, even during the silent parts. Can you hear someone whispering when you're running a vacuum cleaner? Would you consider the whispering to be unwanted noise that reduces the "quality" of other sounds in the room?
