#6 Convert files on-the-fly when uploading

[David Costanzo]

Background:
The audio files on my desktop aren't all in a suitable
format for the handheld. Some are saved as
high-quailty MP3s, which take up too much room on my
PA-1. Others are saved as Ogg Vorbis files, which
cannot be played on my PA-1.

Request:
I would like gnopa to process/convert the files on my
desktop, on the fly, as it uploads them to my PA-1.
For example, gnopa would down-sample my high-quality
MP3s so that more would fit on my PA-1. Likewise, it
would transcode my vorbis files into MP3s.

gnopa does not have to do the conversion, itself. I'm
thinking of something similar to how grip uses external
executables to encode the wav files that it rips.
