Design your own tone-shaped TPDF Dither.

Like PaulDither, but more so.

In normal use, this ‘dither’ (in fact it’s not a dither at all: it’s the Benford realness stuff from Naturalize, run with a noise shaper, and all the added random noise taken OUT) will make any fixed-point output sound like infinite resolution. It has a switch for 16/24 bit operation (defaults to 24) and a ‘DeRez’ control where you can get low-bit NJAD audio if you like, or if you want to audition its noise floor behavior.

Deterministic dither uses Benford Realness calculations for each sample.

The testbed for the TPDF-based dithers. Flanger dither!

TPDF variant with noise like reel-to-reel tape.

Spatial positioning and clarity dither.

Retro ‘groove crackle’ dither with fuller sound.

If you like truncation and artificial vibe, try this!

Single pole highpassed TPDF dither.

TPDF is the industry standard technically correct boring dither. It does nothing strange or interesting, makes no effort to optimize the sound in any way (generally if you make it better for something it’s worse for something else: even Naturalize only has a limited amount of output bits to work with.)

TPDF uses two sources of noise to make what’s called a Triangular Probability Density Function, which gives it its name.
