I've a doubt. When I rip a CD (.wav - 16/44.1 PCM Stereo) to MP3 I'm know the quality loss becouse the code mp3 is more compressed but what happen if I burn from MP3 to .wav - 16/44.1 PCM Stereo? The quality sound is the same of before?
There is no increase in sound quality whatsoever. Once that data has been thrown away, it's gone for good. The 2 main arguments for decoding to PCM are essentially 1 - because your in-car system will not play an MP3 disc. 2 - Because your software MP3 decoder may be tweakable, and decode to a better sound than the one built into the MP3 player can.
