I'm wondering if there is some work-around in Audacity when previewing a section of file when editing so that you can bypass and immediately see the difference of the edited and unedited section. Other programs such as Samp and others have a bypass button you can click to see the difference.
Dude, you should be learning SAM instead of dorking around with Audacity! :P
(Sorry, can't answer your question directly.)
I've not found a preview fx either. Do post back if you find one, please. It'd be a hell of a time saver.
I'll continue to try to learn sam. It took me quite a while to learn aud, but I'll keep plugging along.
There is a 250+ page manual for SAM8 that I have in PDF form. If you do not have it, or cannot find it on the web, let me know and I can e-mail it to you. It is 4K so I cannot attach it. I have SAM9, too.
Cheers
