webstereo: Have a listen to FM radio NZ national and then switch to AM radio NZ national.That's pretty much what the difference is with Eye TV audio on the HE-AAC front. TRanscoding doesn't make any difference either. How can it? If you don't hear it I suspect you may be listening on a laptop.
Umm nope - many 1000's of dollers worth of hifi actually. I use DD for TV3, and mainly watch the news and other non feature type material from TVNZ, so that could be why I just don't notice any obvious problems. I do upsample the signal to 48Khz, however that can't (obviously) bring back what is already lost.
