Sono player

Sonogram player. Your music. Your freedom.
This is absolutely free and unrestricted player for your audio collection. The philosophy of Sonogram is to keep useful features at hands and make this app your favorite tool to explore and enjoy your music.

Please rate my app to make it discoverable for other people.

Main features:
- File system based navigation and minimalistic design
- No ads, no internet and other spurious permissions
- Easy switch between multiple playlists
- Each playlist stores playback information (current track and start time)
- Custom Media Library with smart playlist management and playback statistics
- CUE sheet support. Sonogram detects if *.cue file is present and creates virtual folder in the Media Library. You can use original and cued tracks in any combination thanks to smart management.
- Offline playback statistics to check what you listen the most, mark favorite tracks and ones you hate.
- File signature based indexing: you can freely move your tracks to different locations. Playlists and statistics will work as usual.
- Real-time visualization (log scale sonogram, waveform, spectrum and beats)
- Button to connect to Bluetooth (A2DP) headset or car audio. Control audio by buttons on steering wheel
- Customizable multiple music roots. Player will scan for audio only in specified folders, so system and apps sounds will not be shown in the browser
- Exit button
- Other useful functions will be added soon

Hint: Some buttons and list entries are activated using Long Click to prevent accident triggering. When you run Sonogram first time, it will start building media library. Please give it some time to complete this process. It will happen only once and next time you run the app everything will be smooth.
