I was really talking about noise added by the conversion process. In your cartridge, turntable rumble, your cables and preamp, in the ADC, etc. > By increasing the recording level in order to achieve close to 0dbFS, > you're amplifying the noise of the source along with the signal.

Driving a louder signal into your ADC will improve the SNR. > What if you happen to choose a first-pass recording level that causes > digital clipping?

With good audio tools, you can find/see the instantaneous peaks. I use Cakewalk Sonar, it makes it easy. If you are just guessing, you are completely correct. I was assuming some science. > (One last point: I'm pleased to note that you didn't bring up the > rounding errors bogeyman as an argument against normalisation). Rounding is a pure red herring. If you are hard core, you'd record at 24/88.2, and then use proper dithering to truncate to 16 bits. -- Pat Farrell http://www.pfarrell.com/ _______________________________________________ ripping mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/ripping
