I am reducing the bit depth of some FLACs from 24 to 16bit (maybe keeping 24, I am not sure) and the sample rate from 192k to 48k (per research it’s suggested to reduced in common divisors, so div by 4 is 48k).

The situation is that I am not sure what kind of dither to apply as per research it shows that the less intrusive distortion should be the triangular with shape option, however I have no idea about what shape form, extended shape form, intensity or if I should use adaptive mode.

I hope any expert in the community can give me some suggestions or explain a little more about these options to keep these FLACs as good as possible. Thanks!
