Dithering the digital audio signal

[Wenye]

Hi Everybody,

I'm a new comer to digital audio signal processing.

I'm now need to round-off a 32bit fixed point signal to 24bit. I think I have to add some dither in to reduce error.

Can anyone help on the audio signal dithering or noise shaping arithmetic?

Where to find the resource ? I need detail on arithmetic.


Thank you

Wenye
