Hello from Julia!
You're welcome here, Julia! Please do just ask if you have any questions ... and, good luck with the One Minute Test which is the first step. It might take a little work to get right, but it's well worth doing, so that your recordings are all solidly LibriVox specification. Which in turn means our storehouse, archive.org, can automagically make other file formats from them, broadening our audience even further. (And I can vouch for the misery of not getting the volume setting right, and having to throw away a whole recording because it's MUCH too loud or quiet. )
Have fun here!
Have fun here!
There's honestly no such thing as a stupid question -- but I'm afraid I can't rule out giving a stupid answer : : To Posterity and Beyond!
