Automatic dithering in PT 12.5?

[Carl Kolchak]

Note that PT automatically applies un-shaped dither, when exporting files to a lower bit depth.

The reason being, that exported files are expected to be imported for use further down the line, summed with other files, and require shaped dither to be applied.

In such situations, using shaped dither on the original file export, and then adding further rounds of shaped dither will increasingly cause the dither noise to become an audible hiss.

This is why double dithering (with noise shaping) should be avoided.

Double dither without noise shaping is of no real consequence.

It's up to the end user to apply dither during the final bounce, and to choose the type of noise shaping.

You might be right. From out the video, dither noise is basically tape noise. Tape noise to me it’s basically white noise, and analog devices self-noise is basically white noise too. Though I might be wrong in all this.

This link is broken. Any other site hosting the video?
