So I only speak of Ardour. > If you want to have JACK and Ardour run at the higher sample rate, > assuming your interface supports it, you'd have to create a new > session and import the tracks.

This "up-sample" as far as I understood from the course, does not exist in reality as far as the quality of audio is concerned. A demonstration can be easily made using Audacity and zooming up to see the actual sampling points of both files, the original and the "up-sampled": the file that has been resampled from lower sampling rate will not add anything at all but more sampling points on straight segments of the audio. It cannot add quality. It cannot create curves. What I mean by using a higher sampling rate is for recording purposes. To have more points being sampled when a guitar is played. So that the points can represent closer sections of the wave instead of jumping and making straight lines. > There is no way for Ardour to use files of a different sample rate > without them being resampled to the rate of the session, as > determined by JACK's setting. Which would not be right as it will be better to re-record the tracks that actually need a better quality of sampling. Out of say 15 tracks, there would be 4 that need higher quality sampling because they are acoustic instruments. But the 15 tracks, even the synths and synth drums, will take so many more megabytes of space, because the sampling rate is not set on a per track basis. Maybe sampling rates on a per-track basis does not make sense in FAWs in general. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
