Sorry for your time, please All accept my apologies for this discussion - it was to early to start it - i had questions and didn't found answers yet.

If your A500 can't open a double scan screen, you might want to upgrade it to ECS). I just don't see how you can make comparisons with cd quality if downsampling.
Downsampling (or re-sampling) has nothing to do with time domain.
Yes i will use 28604Hz (sufficiently close to nominal 28603.9919Hz) sampling rate with 16 bit samples to avoid any additional conversion on Amiga (as even in productivity closest to 44100Hz frequency is incorrect - 44336.19Hz).

I will not use any higher than standard TV scan rates(i.e. no productivity or similar video mode).

My goal is to understand capabilities of the '14 bit' audio mode and collect objective data to describe overall audio quality on Amiga.

I'm not comparing Amiga to CD as this will be highly unfair for Amiga - my intention is to use whenever it is possible techniques used for digital/analog audio measurements.
