Most questions are about the same thing: the library is empty, because Mia Audio ships with no content and plays the files you add. That is the first answer below.
No. Mia Audio contains no music and no audiobooks of its own — it is a player for audio files you already have. Until you put a file on the phone, there is genuinely nothing for it to list.
On iPhone, the quickest way is from a Mac:
On iPhone, with no Mac:
You can also send a file straight to the app: tap Share on an audio file in Safari, Mail or Files and choose Mia Audio.
On Android, copy audio to the device's Music folder by any means. Mia reads what the system has already indexed, so anything on the phone shows up. The app asks for permission to read audio the first time it scans.
iOS hides an app from “On My iPhone” while its folder is completely empty — which is exactly when you are looking for it. Open Mia Audio once and close it again; it writes a short readme into its folder, and the folder then appears.
Mia classifies audio by container format, genre tag, and length — anything over
about thirty minutes is treated as spoken word, as is an .m4b file. On
iPhone you can also put files in a folder called Audiobooks and they will be filed
as books.
Audiobooks resume where you stopped. Music always starts from the beginning, which is almost always what you want from a song.
Positions are written every few seconds while playing, and again whenever you pause or leave the app. If a book restarts from zero, check it is actually filed under Audiobooks rather than Music — music is meant to start from the top.
On the Advanced screen, reached from the toolbar, rather than on the transport bar. It is a set-once setting rather than something to reach for mid-listen. It runs from 0.75× to 3×, applies to music and spoken word alike, is pitch corrected so voices stay natural, and persists across launches.
Mia reads titles, artists and artwork out of the tags inside each file. If a file has no artwork embedded, there is nothing to show. Fixing the tags on the file itself and rescanning will fix it in the app.
It should not — playback is designed to continue with the screen off and the app closed, with controls on the lock screen. On Android, some manufacturers apply aggressive battery restrictions that can stop background playback; check whether Mia is battery-restricted in the system settings. If it happens on an iPhone, please write to us with the device model and iOS version.
MP3, M4A, M4B, AAC, FLAC, WAV, AIFF, ALAC, OGG and Opus. Files with DRM cannot be played — that includes audiobooks bought from stores that lock them to their own app.
No. The app makes no network requests at all. Nothing is uploaded, nothing is downloaded, and nothing about your listening leaves the device. See the Mia Audio privacy notice.
Deleting the app removes everything it holds: your audio files in its folder, the library index and your saved positions. There is no account and no server copy, so there is nothing else to delete and nobody to ask.
