> 4) My files were recorded as MP3s, with a 44.1kHz sampling frequency and = 16-bit sampling rate. Perhaps this is the problem... if so, then I am embar= rassed to say that it's a problem I'm stuck with, as that was the default f= ile format, no one mentioned that it wouldn't be good enough, and I didn't = know enough to change it. http://soundcloud.com/laura-hilberg/nesp-song-short-clip Hi Laura, I just looked at your file and can confirm that there is indeed no clipping= , but unfortunately mp3 compressing artifacts. I'm sorry about that. We discussed such lossy audio compression artifacts on this list many years= ago. At that time I created a page that tries to explain what can go wrong= with mp3 or ATRAC : http://www.avisoft.com/compression.htm Regards, Raimund |
