I have been trying to downmix 6 channels audio files into 2 channel ones (ogg/aac -> wave). The process completes normally, but the resulting file is full of breaks, pops, and crackles. These artifacts are not in the original files. I have tried to convert from AAC and Ogg formats directly but get the poor quality. I have also tried converting ogg files (using oggdec and faad) into multichannel wave files (which still have no artifacts), and then using dmc to convert those into stereo wave files. Artifacts still remain. Other programs such as foobar2000 and faad (with downmix option) can convert these files with no problems at all, but I like dmc and would love to continue to use it. :smile2: Any ideas on fixing this problem is appreciated. Thank you.
