I have like 365 audio files to convert, that would take ages!
Using a converter program which can convert all files at once would be more convenient.
I'll check out the site though. Maybe it'll work, maybe it wont. I guess I wont know unless I try.
I'll let you know how it goes.
Edit: It didn't work.
Error
Sorry, the file type acb is not currently supported. Vocaroo supports: mp3, ogg, flac, wav, wma, amr, m4a, aiff, aif, aac, mp2, gsm, 3ga, au and ra.
It was worth a try though.
