Even if you’re keeping the same bit depth. <\/p>\n\n\n\n
The short of it is, that the bounce down, say from 96khz\/24bit to 44.1\/24bit is going to raise your True Peak and integrated LUFS by .2-3<\/strong> points. When you apply dithering, it tames that gain to only .1 point<\/strong>. There are technical reasons for this, but the short of it is, my last track I recorded in 96khz\/24 bit in logic and for what ever reason when I googled about Dithering, the impression I got was that it was only necessary if you were reducing the bit depth, say from 24 to 16, which has been the common practice for years. <\/p>\n\n\n\n But lately Spotify, Apple Music, and I assume the others are streaming in 24-bit, so I didn’t feel the need to dither. But then I noticed that jump after bouncing. Dithering solved the problem, or at least most of it. There still was a .1 jump both in True Peak and iLUFS, but not the .2-.3<\/strong> point jump that you get otherwise. There are three Dithering options in Logic Pro X bouncing: Regular, and two different “Noise Shaping” ones. I tried all three, but at least for my song, they sounded the same and gave me the exact same readings on all the parameters of my Youlean Meter. So I just went with regular, the first choice.<\/p>\n\n\n\n Here’s a comment I just wrote on a Youtube video by the brilliant “In the Mix” channel that I will link to at the end:<\/p>\n\n\n\n Looking at those guidelines, does it mean if you keep your TP below 2.0 Spotify will let you get away with a little louder LUFS? The most recent song I uploaded had a TP of -2.1 and an integrated LUFS of -13.4. Since I kept it below -2 TP do you think they’ll let the .6db “slide” so to speak (as we say here in the States,hehhe) or will they reduce it still? The guidelines are a little obscure. They say if you are going to master louder than -14LUFS then make sure your TP is below -2. So I wasn’t quite sure how to interpret that. For sure with indies like myself, the holy grail as it were is to have a sonic quality and loudness that competes with the majors. Oh another think I’ve learned: You’ve got to employ dithering, even if you keep the same bit depth on the bounce or mixdown. I accepted the Youlean measurements within the mix because they were the very last on the stereo buss chain. But the mix down from 96\/24 to 44.1\/24 even keeping wave lossless bumped up the TP and iLUFS by .2-.3 points. Employing dithering tamed those losses to only .1 And the readouts were exactly the same whether using regular dithering or the two “Noise Shaping” varieties.
