you go to file > export > mp3

but you have to download the lame mp3 encoder off the audacity website then open it in audacity, go to the audacity thread sticky and therell be a FAQ there id assume. thats what the thread is for man.

no it doesnt

it allows you to convert all of it. what would be the point in it only allowing 60% ?

to get you to buy the whole thing...i searched all over the internet trying to find a wav to mp3 converter and i couldnt find one that allowed me to convert the whole file
No no no go to Audacity man.

File -> Export As MP3

Thats right; I even looked for you. See, how nice am I?
And Audacity remains FREE!
