Equal Power Crossfade Loop - when? -Sound Forge - PC

Subject:Equal Power Crossfade Loop - when? Posted by: Skaven252 Date:11/28/2006 7:17:17 AM Every time a new release of Sound Forge comes out my first question is, "Does it now have equal power loop crossfade?". Since this essential feature still has not been implemented, I have to ask here: When will it be? The current linear crossfade always causes a volume dip in the loop, no matter how carefully I try to align the wave phases or what not. I'm sorry to say this folks, but the tool is more or less useless if it stays this way. I had to switch to Steinberg WaveLab Essential (released back in 2002) because of this. For demographic reasons, my job is audio development for games. My use of a wave editor like SF / WL consists mainly of properly looping audio files created in Vegas.

Seems to me like it would be easier since you can slip-edit while listening to the result, rather than having to paste/crossfade, listen, undo ... over and over again.

Reply by: Skaven252 Date:11/30/2006 12:37:53 AM In theory this would be great, as Vegas has really good automatic crossfades that can be tweaked at will. I've tried it, but in practice it's rather difficult. I usually have multiple tracks in the project, so each track has to be spliced into a loop separately. Furthermore, there's EQ and reverb that cause the final result to click no matter how carefully I try to splice the tracks to loop. For these reasons, the looping has to be done in post. Sure, I could render the project into a new track and loop that, but Vegas doesn't write proper sustain loop markers into the WAV header, so I would still have to open the sample in SF/WL to add the loop. Also, for some reason, Vegas sometimes writes a few bytes of empty space into the beginning or the end of the sample, which has to be edited out.. The Vegas Trimmer is conveniently built into Vegas, and can already save Regions and Markers into the WAV headers. Maybe it could be enhanced with a destructive loop crossfade feature? There could be a "Render project into Trimmer for looping" command which would do exactly what it says, then you could use the Trimmer's new equal power crossfade feature to loop the sample, then save the sample and write proper loop markers into the header. Wouldn't that be something! I guess I should suggest this in the Vegas forum. :) Looping used to be pretty convenient with WaveLab. I associated WAVs with WaveLab, then used the "Preview in Player" command to quickly render the project and open it in WL, loop it there and save it. But we now have a new plugin which I must use on every sample (ReLoop), and it currently only works in Sound Forge. http://www.bobandbarn.com/reloop Message last edited on12/1/2006 1:19:10 AM bySkaven252.
