That statement there is bullshit. Scanning a wave-file for maximum absolute sample and then scaling that to make the file fit into [-1:1] with the abssolute of the maximum sample at 1 _is_ normalization. That is the very definition of normalization. > That would be okay, except I want them normalising to something other > than full scale. Given the fact that [-1:1] is just an arbitrary setting, there is no problem with normalizing/scaling to [-0.9:0.9] or within the range of -3dB instead of 0dB... > Is there a quick and easy way to do this? I seem to recall that normalize-audio can actually do this. Otherwise have a look at the fine tools contained in libsoundfile. Have fun and a merry Christmas, Arnold
