It explains why I've been feeling the mp3 decoder needs a complete overhaul. As it is it isn't worthy of inclusion in a serious DAP. The thing I first noticed was the horrible quanitization noise.
Could you do the same measurements for the ogg decoder so we can see what is so seriously flawed in that too.
And while I'm whining, can FiiO please note that the mp3 decoder is most certainly not capable of gapless playback.
I thought that it should be audible. I´ll measure ogg too. Stay tuned.
