I've never encountered this issue, but on the current song I'm making in EoF, I'm unable to create a preview. It brings up the option to encode in whichever bitrate, but after selecting a bitrate, it does nothing. There is no file that was created in the folder as well. 

 

I have tried creating a preview on another song, and that preview is created just fine. 

So neither the preview OGG or WAV files are created? Does it matter whether you change the start and stop position of the preview? Can you send me the EOF project and OGG file you're using with this chart?

Simple: don't use the preview creator in EOF, ever.

 

Use audacity instead (import the song into audacity, then cut it down to what you want). Audacity will also let you add fade in and fade out effects to your preview, which is present in all official DLC.

@L33trь, lol I scripted out fade-in\fade-out for eof's preview and it's works well without any additional steps, just drag on batch file your preview and it will do that job for you in seconds ;) I can share this method if you need to :)

Even though that is probably a whole lot easier, I'll probably just stick to audacity. It's grown on me lol

Call me crazy, but I'd rather fix problems than tell people they'll always have to use something else. I'd still like the files to test with for that reason.

 

Heck, I could probably even program EOF to automatically try to fade in/out on the preview, I just have to know the proper logic to use (ie. how fast to alter the amplitude values, and whether it's better to try to use a logarithmic multiplier instead of a linear one, etc).

I wanted to report my findings about this issue. Thank you all for the replies; I believe I have determined the issue. The track I was using contained an erroneous punctuation mark (a '?', to be exact), which caused confusion when EoF was reading the file. Consequently, the .ogg file for the original track was named "guitar.ogg" and a preview could not be created. So the fix is to simply change the metadata within the original track to remove the '?'. 

Having certain punctuation in the song title certainly could prevent the preview audio to be written, since the WAV file is created using the song title, and the OGG file is created from the WAV file. I'll have it automatically try to save it as "guitar_preview.wav" if the file can't be written using the song title.
