Dropbox is an important tool in the voiceover industry; some agents--including mine--require audio files to be uploaded to a Dropbox folder. A lot of clients have replaced FTP with Dropbox because of the ease of use for both sides.
Time is of the essence when auditioning. VOs have to record when it comes in--whether they're in their booth, in their car...it has to be done now. We can record on the go using our phones and tablets...and then can't upload the files to the folder, because the app only lets you upload pictures. And it's just not practical to take a laptop everywhere.
Please consider including audio uploads from the device app. Dropbox is an industry standard now, and it would be nice if the app would accommodate our need to upload files from our devices at any time.
