Re: burncd audio produces white noise
All, Thanks for the responses. Based on your input I did find that, following the handbook, 1. Starting with a known good audio CD 2. Rip via dd if=/dev/acd0t01 ... etc 3. burncd -f /dev/acd0 track01.cdr ... etc worked just fine. Thus the MP3 to CDR conversion had to be the cause. I used the command (tnx Lars Eighner) mpg123 -sr 44100 filename.mp3 filename.cdr and then burncd'd these tracks...worked! I don't know if the underlying cause is sample rate, or byte-order. But I have a solution...So...I'm back to getting music together for my daughter's wedding...I'll solve the final mystery another day :-) tnx all Mike At Mon, 15 May 2006 08:00:48 -0400, Michael A.

Most likely you are confusing byte-order. Might also be a problem with the configuration options for the respective ports Something was confusing byte-order, that's for sure (or -swab wouldn't help) however, when I ripped, I would use madplay, not sox... and I *believe* that I had tried the dd method from CD to CD as outlined in the handbook and it failed too. I'm groping for details because I don't burn audio CDs very often, but when something is converted from mp3 to cda, then the resulting cda is burnt to a CD on the same system that did the conversion, it should Just Work. iirc, the CDA format uses the hosts byte order so burncd (or morelikely, the device) would need to use swab() when burning on BE systems. Definitely something for Michael to try is following the steps outlined in the handbook for copying a CD and see if he still has the byte-swapping problem. ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]
