Or at least choose a media directory to store. As @spark and @slava discussed in https://forum.sailfishos.org/t/restore-specific-folders-from-a-sailfish-backup the audio recordings land in Documents and don’t seem to be backed up. ~/Music would be a better directory, perhaps?
An option to store recordings on SD card would be fine. I can’t find any options for recordings neither in Settings/Apps/Audiorekorder nor in the app itself. It’s sooo spartanic!
edit: also settings for sample frequency and sample resolution (8 bit, 16 bit) would be fine!
