I think two things makes me at least rethink this . These recordings are not as rare as they should bee , yuk ! Hardware components and hifi companies live in oblivion , far more devices than we think are affected ! Especially for IC's made as cheap as possible , then you may not use a DSP with real floating point math for your filter (or whatnot ) and still wants nice SN/ratio numbers. The old research i dug up saw this in all the tested equipment , so it may actually be that its the rule for consumer electronics rather than exceptions .*sigh* (dont we pay for "hifi" no , lets use the same cheap IC's as everyone else and throw some Tubes and Fancy case work at the problem ) But i would not invoke SoX is it not enough to just turn down the digital volume a bit ? Having a constanly running transcoding process on the server has other issues and is SoX itself "safe" . Just turning down the volume could have some theoretical impact on 24bit material but , somewhere with the noise of my dust-mites in the other room ... Q for you experts . Can this happen with a "valid" signal going trough a lot of processing . Lets Say you capture something trough a perfect AD (No signal above nyqist ,perfecly bandwith limited before sampling) and it just hits 0dFs during one sample . Would lets say an oversampling fillter still be able to create intersample peaks with this signal , does it matter if its asrc ? -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
