[LAU] standalone pitch correction

Hi listers, I'm working on a project and being constantly reminded that, though I'm not bad, I'm an imperfect vocalist. :( That's just the breaks. Anyway, I'm using Nama with Ecasound which allows me to do my production from the commandline, which is necessary because I am blind and it's my only option right now, but his powerful tool does not, at this point, play nicely with the lv2 plugins like talentedhack which provide pitch correction. Does anyone know of a cli based method of pitchcorrecting an audio file? I mean I want to tell it what key I'm singing in, set some parameters, and have it process a file to fix some of my intonation problems. You might say, why not just sing it again? Honestly, I don't have the patience or the time. Anyway, if anyone has a suggestion, I would much appreciate it. Thanks! Rusty
