Tuning... autotalent doesn't seem to do anything

[lykwydchykyn]

I've got some trumpet parts I recorded and I've been trying to tune them in Audacity using autotalent. I don't know if I'm doing something wrong, but it doesn't seem like it's working.

To make sure, I took my original track and played it against the tuned track and, sure enough, they were on the same pitch. I'm not that good of a trumpet player (horrible hack, really).

Does anyone else use autotalent to tune things? Does it work well for you? Every time I've tried it, it seems to make things sound worse and introduce artifacts. I have to believe I'm just doing something wrong.
