Distortion Problem on Sansa
X86:
the real audio codec is like wma for microsoft,the real audio codec is like an improvement of the wma codec,I had my sound library in dap as wma files,but now I converted my sansa into a rhapsody one and I converted all my files to real audio,also I used rhapsody music management and it transfer the files really fast :D

Ah, thanks, I didn't know RA is just a container format. I had bad experiences with some of their earlier stuff. Now this looks interesting for lossy:
raac: MPEG-4 LC-AAC (RealAudio 9)
racp: MPEG-4 HE-AAC (RealAudio 10)

I do have replaygain values in all my files (Vorbis encoded with the latest AoTUV). I have replaygain turned on and "prevent clipping" turn on, but I do hear the slight distortion the OP is referring to. However, I am not that sensitive to that artifact, so it is acceptable to me.

Well the thing is, if we're producing distorted output, then 1) It should show up on RMAA tests, and 2) We need to fix it. Can you provide more information?

distortion on sansa?,I dont feel it,and about real audio files,those are better and wma too,but real audio codec is like an improvement to the wma codec,but in another way as container,if you use a 128kbps encoded wma the equivalent to that file in wma is the real audio at 160kbps,almost same size.What about distortion,may someone explain me on what consists that?,I know what is distortion,but what is the sound.
