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!
What software are you using?
My original idea was to try checking if I can notice the difference between one of those massive 24-192k or even f32-384k, and some more conventional 16-44.1k or 24-48k. But after some checking around I got stuck in the dither option and I found a little hard to understand the algorithm differences.
So basically it was a small experiment and since apparently files over 24-48k are suppose to be non distinguishable for most humans (if not all, but that is probably a can of worms I don’t want to open), I found those massive hires files to be a waste of space for no particular gain other than brag about how many TBs of hires music I have. Anyway, I am still learning :D
