We use Audacity this way pretty heavily. After writing the changed file back to /var/snd/ we always open the file again in the Library editor because the markers will need to be reset. That task alone resets duration intervals. Previously I have mentioned that we use the WAV editor in Exact Audio Copy for simple work like straight cuts and easy fades. It is a difficult interface because one has to manually draw the interval each time as you cannot extend or shorten a defined interval. But EAC does not introduce any noise. Audacity, on the other hand, we use to add more natural ringout reverb to songs that end abruptly, or need volume level adjustments at beginning or end. We raise some song fadeouts so they do not go on eternally for 10 to 15 seconds. You can do this with the envelope tool: place an envelope marker where you want to start raising a fadeout; right click in the volume scale to the left of the track, which doubles the volume scale; put another marker down the line, only this time at the louder x2 volume level; then Tracks > Mix and Render. Rinse and repeat if necessary (it usually is for long fadeouts). The drawback to Audacity is that it converts from WAV to its own 32-bit floating point audio encoding. Then you have to export back to WAV. That process definitely adds enough noise that it could be above the auto-trim level you may use (we use -71db). But then a lot of pre-digital era tracks have rumble or hum that is above that floor, which causes manual setting of markers, so I guess it is not an awful price to pay for Audacity's capabilities. But the EAC editor does not add noise, and that is why we try to use it first whenever possible. I must say that Rivendell is one of the most time-accurate systems I have ever worked with. At the end of the day, the final event fires within tenths of a second to what it said it would at the start of the day. That's pretty awesome to us. --Chuck W. _______________________________________________ Rivendell-dev mailing list Rivendell-dev@lists.rivendellaudio.org http://caspian.paravelsystems.com/mailman/listinfo/rivendell-dev
