Traditionally, an instrument would only have one or a few samples per octave, so resampling was required to even implement note pitch at all. These multi-gigabyte piano and orchestral sound disks may not make much use of that feature, but that's a special use case that came with live streaming from disk and machines with gigabytes of RAM. I'd think even samplers built specifically for this would still have the usual resampling features, and should work with any output sample rate - but of course, you're not getting any advantages from 48 kHz if you're still playing 44.1 kHz sample libraries of that kind. -- //David Olofson - Consultant, Developer, Artist, Open Source Advocate .--- Games, examples, libraries, scripting, sound, music, graphics ---. | http://consulting.olofson.net http://olofsonarcade.com | '---------------------------------------------------------------------' _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
