![]() Quote from: pdq on 14:47:53 If Audacity gave you silence with and without dither then it was not doing what you think it was. It's probably helpful at 8-bits (around 40dB down). But in the real world at 16-bits, anything that's around 90 dB down is not going to make an audible difference (in a blind ABX test). You know dither is supposed to make a difference (an improvement), or there's no point in using it. You've got two unknowns, so you probably also need to dither with one editor and subtract with the other to find-out where the difference is (2 more experiments). It's also possible that something's wrong with your "mixdown" procedure, which should of course be subtraction. I assume it was VERY quiet and you had to crank-up the volume to hear it? The more "aggressive" the dither, the more likely you are to hear it in a null/subtraction test. I would expect different dithering algorithms with two different audio editors. ![]() (this kind of surprised me as I expected it to be silent).It's possible that Audition is doing some kind of "unexpected" dithering. Quote and made a mixdown of them in Adobe Audition 1.5, in the mixdown of the 2 tracks I can hear quietly the audio of the song with a very bassy bass drum. Is Adobe Audition doing it's job properly there? Is it odd that the same process in Audacity created a silent mixdown but the mixdown of the files created in Adobe had faint music? I then did the same thing with Audacity (instead of Adobe Audition), normalized a track to -0.01dB, once with dither and another without dither, when I made a mixdown it was silent, with NO music, unlike the Adobe Audition mixdown which had quiet music. (this kind of surprised me as I expected it to be silent). I normalized an original track to -0.01dB, once with dither and another time without dither, then I overlayed the output files of the dithered and not dithered normalized files and made a mixdown of them in Adobe Audition 1.5, in the mixdown of the 2 tracks I can hear quietly the audio of the song with a very bassy bass drum. running through same edits with and without dither to see if I could hear any differences etc., and came across something I'm not sure I understand. I was testing out Adobe Audition 1.5 on a few various things, eg.
