Serious bug in SF9 batch processing -Sound Forge - PC

Subject:Serious bug in SF9 batch processing Posted by: Laurence Date:2/5/2009 5:43:17 AM I am in the middle of trying to convert some of my sound effects libraries to .flac format in order to save disc space. In doing this I'm running into a pretty severe problem where all the short audio clips are being converted to silence instead of the proper audio. I've converted a little over 2000 files this way and all the short files are silence. Going through all these short files to see which ones are silent and manually converting the ones that are is just too time consuming to imagine. edit: It's even worse than I thought. Even some of the longer clips even some of the longer clips have sections of silence at the tail end. Has anyone else run into this? This is the first time I've actually needed to use the batch processing function and as far as I can see so far, it's too unreliable to be of any practical use.

Subject:RE: Serious bug in SF9 batch processing Reply by: Laurence Date:2/5/2009 1:08:27 PM Sure, my test was a real world situation. I took the complete Sony 10 disk sound effects library in .wav file format and ran a batch convert to convert them all to .flac. As I auditioned the converted audio, I noticed that some of the samples where now nothing but silence. I put both the .wav and the .flac files on a Vegas timeline with one above the other so I could see any differences in the waveforms. Most the files that were around a second or less became flat lines. A small percentage of the longer files had flat lines at the tail end where the audio was muted after the conversion. I have no idea of whether this happens on all systems. I do know that I tried the conversion a couple of times. Maybe it is just on .flac conversions. Maybe it is worse when you have a mix of stereo and mono files like you have in a sound effects library. Whatever it is, it is not consistent enough for me to actually use this feature. It's a shame because it is a really cool feature.
