When in doubt, dither - Production Advice

WebNoise‑shaped dither subjectively sounds quieter than simple triangular dither because it takes advantage of the ear's non‑linear frequency response to low‑level sounds, although the total dither noise energy remains exactly the same for both forms, and that's the critical aspect as far as proper dithering is concerned. WebFeb 21, 2008 · Pow-r 1--noise-shaped dither. Advantages: less CPU-intensive than Pow-r types 2 and 3, lower perceived loudness than Rectangular or Triangular. Disadvantages: less noise shaping than Pow-r types 2 and 3, not recommended for operations where dither will be applied successively (e.g. bounce and freeze). Pow-r 2--noise-shaped dither. WebWhat is triangular dithering? The triangular method is characterized as a quieter, more constant, and higher pitched hiss than rectangular noise (sometimes called blue noise). Shaped dither is noise with a carefully contoured frequency content that puts most of the randomization at frequencies we can hear least easily. crystal\\u0027s 4k
