I cannot upload files to the cloud service.

The file size is too large, or the cloud service may not support WAV file format.
Please reduce the file size by converting file format as below and upload:
-WAV files -> AAC files
-AAC files -> AAC files with lower bit rate
Follow the steps below to convert file format.

１. Swipe left on the file on the FILE screen.
２. Tap [Edit].
３. Tap the current file format (e.g. AAC 320kbps).
４. Select a file format to reduce file size.
５. Save the file (Overwrite/Save as).
