Title: Question about decreasing Bit Depth in Sound Forge (from 24 bit to 16 bit).
Post by: chinariderstl on November 25, 2015, 02:21:35 AM

Hi, a quick question for the board, I have a source stereo file that is 24 bit/96 kHz.  I have successfully changed the Sampling Rate from 96 kHz to 44.1 kHz using the Process > Resample tool in Sound Forge with the Interpolation accuracy set to 4 and an Anti-alias filter applied.  I am now trying to reduce the Bit Depth from 24 bit to 16 bit using the Process > Bit-Depth Converter utility.  Within that utility I select the desired bit depth (16 bits), but there are two drop-down menus that I'm unsure of: Dither and Noise Shaping.

In the Dither drop-down, I have the following options: None, Half Rectangular, Rectangular, Triangular, High-pass Triangular, and Gaussian.

In the Noise Shaping drop-down, I have the following options: Off, High-pass contour, and Equal loudness contour.

Any ideas what those should set to?  Any recommendations?

Any help is greatly appreciated.

Thanks, Chris.

Here's what I use

  High-pass Triangular,    High-pass contour

I think it sounds better, but that may just be my ears
