A: Hi Leintje,

that shouldn't be a problem at all! We support uploading the following formats:
'mp3', 'mp4', 'm4a', 'mpeg', 'mpga', 'wav', 'webm', 'ogg', 'flac', 'aac', 'opus'

Keep in mind though that we don't have a phone app so from the phone you still need to get it to your computer.

We will in the future also have a phone app but that is still under development.
