To change things to 48k you would have to do that outside of ardour. I would suggest against doing that except as a final step after mixdown as any time differences from track to track in the resample would be magnified by such a long track. Even in shorter cases stereo imaging could be affected. It would be best to leave 44100 if at all possible. If the end product _has_ to be 48k then expect a (hopefully small) loss in quality. Ardour will switch it to 32bit float internally whatever the input is to allow mixing headroom. 24 bit is chosen at export time. However, again this would be decided by the final delivery route. -- Len Ovens www.OvenWerks.net _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
