I know, the only solution is ABX test, but in the real world, MP3 320 is worse respect to a 256 AAC?
if you can't be bothered to do even a basic listening test
This is discussed regularly, but if you can't be bothered to do even a basic listening test then start with LAME VBR V2
If you cannot tell the difference between the two then they are the same quality.We're talking about lossy compression here and since it is lossy compression there is no other means to determine quality; none, nada, nothing, zero, zip.
what about examining waveforms?
also, Is there one that is generally regarded by the community to be better? or are they generally seen as being interchangeable
My point is that for me it's not a choice between lossless and lossy, but which lossy will sound best to the most people on a huge soundsystem - which is hard to A/B at home.
Both highs and low end are critical. I know I definitely prefer the highs of 256 AAC over 256 MP3 but the choice between Google Play's 320 MP3 and Itunes 256 AAC is harder.
I've been opting for 320 MP3, but love some experienced djs thoughts.
