If you have a 24-bit DAC, you won't hear the quantization noise added by changing the volume. Even if you did, you could turn off the replay gain and get the original audio. That's why it is still considered lossless.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Brian Willoughby</DIV><DIV>Sound Consulting</DIV><DIV><BR class="khtml-block-placeholder"></DIV><BR><DIV><DIV>On Apr 2, 2007, at 05:02, Harry Sack wrote:</DIV><BR><DIV><SPAN class="gmail_quote">2007/4/1, Ivo Emanuel Gonçalves <<A href="mailto:justivo@gmail.com">justivo@gmail.com</A>>:</SPAN><BLOCKQUOTE class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Those are Replay Gain elements.
