En/na Erik de Castro Lopo ha escrit: Thank you Erik. Great program! I did it with http://www.mega-nerd.com/SRC/. However when I started again ardour and played the song, at the beginning of each inserted WAV the sound was muted (as if it was clipped). It is an ardour problem as with rezound I checked that the files were perfectly upsampled. Finally, in ardour, I had to trim some WAVS at the beginning and everything was solved. Weird but worked. I paste here the script I executed in the "sounds" folder of the ardour's session, to upsample my WAVS to 48k. Hope it is useful for sbdy. Don't use it without making a copy of the ardour's session before because of the problems I have already commented above. #!/bin/sh if [ "$1" = "" ] then RATE=48000 else RATE=$1 fi echo "All wav files will be overwritten upsampled at ${RATE}Hz, be careful. Press Enter to continue..." read for file in *.wav do echo "Upsampling to ${RATE}Hz $file..." sndfile-resample -to $RATE "$file" "$file.tmp" mv "$file.tmp" "$file" done
