POWr Dither

What's the difference between the noise shaping options in this little program, I can't really hear the difference?

Hi there,
Well, one of the other reasons you might not have gotten the response you were looking for is that your question is one that you could easily answer for yourself by reading the manual.

However, here is the explanation that I've copied strait from the manual for you...

The POW-r Dither plug-in provides three types
of noise shaping, each with its own characteristics.
Try each noise shaping type and choose the
one that adds the least amount of coloration to
the audio being processed.

Type 1 Has the flattest frequency spectrum in
the audible range of frequencies, modulating
and accumulating the dither noise just below
the Nyquist frequency. Recommended for less
stereophonically complex material such as solo
instrument recordings.

Type 2 Has a psychoacoustically optimized low
order noise shaping curve. Recommended for
material of greater stereophonic complexity.

Type 3 Has a psychoacoustically optimized high
order noise shaping curve. Recommended for
full-spectrum, wide-stereo field material.

So, if you are bouncing music, stick with Cucco's advice and use Type 3.

Well hey there Mark...

No need to be so down about it.

The fact is, there are tons of pros on this board. Speaking for myself, it's a VERY busy time of the year and I never saw your post.

The differences in each POW-R algorithm can be found on Dan Weiss's web page IIRC. Personally, I hear only minor and subtle difference between them all but my ear almost always leans towards POW-R 3 as a preference.
