Click on the files below to hear what each of the popular dithering curves sound like. Mind you, they’re sitting below the noise floor; typically at -120db, but since digital has no internal tape hiss or noise, I simply raised the volume by 100db so you can actually hear what dithering is.

The pow-R3 curve was developed by WEISS AUDIO, and is now practically the “industry standard” when it comes to any kind of rock or pop music. To my ears, it’s the quietest one of all, even when mastering classical pieces of music, although many mastering engineers ears prefer the pow-R1 curve when it comes to light jazz and classical music.
