I have transplant madplay to embedded linux2.4.18. When I play the mp3,it has a loud noise in the music. Has anybody met this before? Can anybody help?
I remember problems very much like this when I was first creating mpg321, and IIRC the problem was a 'signed' issue. Perhaps 'char' is signed on your platform, and your output needs unsigned?
I do remember the fix not making sense to me. PCM samples can be negative, I think, but I believe that I had to change to using unsigned char explicitly.
Hope this helps,
