Looks cool, but there is a problem in your procedure. soxmix does something else than just adding up the signals, therefore it is not possible to restore the original file. If you try a different approach (preferably lossless), you will see that vorbis+flac size is bigger than original flac file. -- Miroslav Lichvar ------------------------------------------------------- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.
