....depends on the length of the tune and what encoder program you use....Lately I've been using a program called CDH Media Wizard, and on average it takes, about 3-5 minutes to convert one tune from wav file to an mp3 file...The uploading process will depend on how fast your connection to the internet is......but figure the average mp3 file can range in size from a meg and a half to 4 or 5 megs, again dependent on the length of the original tune..
