Therefore if 16bit music is played using wasapi shared mode, it is better to set shared mode device bit depth to 24bit or 32bit rather than 16bit. If exact 16bit values get no noise added, and nonexact 16bit values get noise added, then the noise power depends very strongly on signal amplitude.

It shows you theres still truncation in floats, and it shows you the way tpdf dither completely removes the truncation distortion. The idea behind using the shaped dither by default is to be always on the safe side.

Is there a big difference in quality using audirvana or. Lighter, fully software implemented version of the original. It is what it is, i still get a load of isps after the limiter with the new version, and it does seem to change the sound quite a bit.
But its not as simple as that as the 0 db reference level on pcm is 6 db reference level on dsd to conform to sacd standards. Airwindows tpdf dither is a nice highresolution wellcoded implementation, one that does the truncating for you so you can compare it for instance, with bitshiftgain like in the video but its also exactly the same as any other properly done tpdf dither out there. This plugin marks the opensourcing of everything ive ever done dither wise, including the benford realnessbased not just another dither named by the internet. The figures below show some average loudness obtained from a group of people. These are the recommended versions of my components. With 24bit music you can listen to silence much louder.
