all the files in /var/snd have just a filename which is the cart number and the cut number eg 814948_001.wav which is cut 1 from cart 814948 all the Cart Data is stored in MySQL [a great feature of Rivendell which keeps audio as just audio] So you save GROUP and Scheduler Code data as well.
There is no cartchunk data in the audio files stored in /var/snd if you resample the audio and save in the new location /source/var/snd > resample 48000 to 44100; keep the file name and save in > /new/var/snd your entire library will be accessible as before by the new system There are several resample options which you can build into a shell script and I would add a ' normalise to -13 ' in there so the levels remain the same on the sound files. The playback levels will be determined by the already set parameter in RD Library. As will the segue points. [Great System!] If you use rdimport Alessio, your music files will all need to be identified and set in groups because they will all come in labelled with the old cart number as the title. Have you figured out what resampling software you have on the new box If you are using the Centos appliance CD you have sox sox infile.wav outfile.wav rate -m 44100 gain -n -13 should give you a result I would run some through and have a listen.
