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. Premium raises the cap considerably, and the format has its own 4 GB ceiling above that, which is why long sessions come split into numbered parts; upload them together and they are treated as one job. 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.
