Free accounts cap at 100 MB per file, and WAV runs to roughly 10 MB per minute in stereo because nothing about it is compressed - every sample is stored at full width. Ten minutes is already at the limit.

WAV yana da girma - kusan 10 MB a kowace minti na stereo a matsayin CD - kuma sifar classic tana da 4 GB na tsayi kuma babu wuri ga alamun shafi na daidai.
