The first time you select a folder, Android will ask for file access permission. This is normal — without it, the player cannot read your music.

Settings Tab

Reset sound settings

Resets equalizer and spatial effects settings to zero values.

Reset equalizer settings for radio stations

Removes the binding of favorite radio stations to equalizer settings.

Export all

Saves all settings (effects, equalizer, profiles, favorite stations, station profiles, last track) to a .json file. By default, this file is named spatial_backup.json and is saved to the "Downloads" folder. If desired, you can change the save folder and file name. After choosing a save folder, the program will remember this folder and offer it by default.

Import all

Loads settings from a previously saved file (the program remembers the last export file and loads information from it). When importing, data is added to existing data, not replacing it.

Export the export

Allows you to save the export file somewhere else to avoid data loss.

Delete export

Allows you to erase the export file.

Automatic station check

• Live station check — launches a background check of all favorite radio stations. Runs via WorkManager: the app can be closed, and the check will continue.
• Header indicator — during the check, a pale blue spinner rotates to the right of "Spatial Player Pro".
• Notification — when finished, a notification "Found non-working: N" appears. Tapping it opens the Settings tab.
• Delete non-working — the "Delete non-working" button in the Settings tab removes all stations that have not responded after three consecutive attempts.
