No, normalization is simple. Find the highest (or lowest) value in the tune, multiply every single value by a constant so that the highest (or lowest) reaches the maximum value of 2^15 (usually plus or minus one) It is simple 5th grade arithmetic. Any value of zero is kept the same, because 5th grade arithmetic teaches that zero times anything is still zero. Compression is the term where the loud parts are compressed without impacting the soft parts. > Gain normalization in my > software does not destroy dynamic range within a cut, it simply looks > for the loudest passage and makes that peak the full scale output of > the DAC counts and re-calculates by ratio proportions all of the other > values required to maintain a linear file. Correct. It has no impact on relative range. It impacts absolute values. But it multiplies all noise and all other signals by the single constant. It makes the noise louder. There is a tiny chance that the software you are using means something else when it says "normalization" but the standard term means multiplication of all values so that the peak is zero dB full scale. > That > being the case, I process albums as single large file, then chop it > into pieces as the final step for burning CDs. That only means you select the single constant for the whole album rather than for one song. The impact on the sonic purity is the same. > Of course, I don't need to burn CD's now that I own an SB. What about burning mix CDs for your car when you do road trips? -- Pat http://www.pfarrell.com/music/slimserver/slimsoftware.html _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
