Solfeggio Frequencies
Waveform
Binaural Brainwave Beats
Use headphones. Binaural beats work best below about 30 Hz; higher values sound rougher.
Ambient Sound Mixer
Softness removes harsh high tones. It helps with crackle on Bluetooth headsets.
Choosing a sound while its volume is 0% raises it to 40% so you can hear it. New sounds download on first use and then work offline.
Play, previous and next are in the bottom bar.
Turn on 8D in the 8D tab to move the music around your head. 8D Amount blends it with the original stereo. Turn Base Frequency off to hear music only.
Library
Choose
Your phone's file picker shows all your music, and you can select many songs at once. If your phone allows it, Add folder adds a whole folder. Files are copied into this app on your phone and never uploaded. Your originals are not changed.
Sound Path
Route
Shorter cycle = faster movement. Intensity does not apply to Back ↔ Front via Center. With a binaural beat active, only the ambient layers move so the left and right tones stay separate. Drag the head view to look around, pinch to zoom.
The guide runs while sound is playing.
Rhythm (seconds)
Saved Presets
Sleep Timer
Sound fades out over the last 20 seconds, even with the screen off.
Theme
My Wallpapers
Your photo is resized and kept only on this phone. The app darkens it where needed so text stays readable, and picks colors that match. Up to 5 photos.
Adjust Crop
Drag to move. Pinch or use the slider to zoom. Keep the main subject in the middle: the shaded top and bottom are covered by the header and the player.
Limits how loud the app can get. The right end of the volume slider equals this level. Your phone and headset volume still apply on top.
Adds notification and lock-screen controls and helps keep sound playing with the screen off. Sound still plays directly. Turn off if you notice any problem.
Music library limit
A bigger limit lets you keep more songs but uses more phone storage.

Backup & Restore
Saves your presets and breathing rhythms to a file. Music files are not included. Use it before clearing app data or reinstalling.
Tips
Headphones: use them for 8D and binaural beats.
Crackle on Bluetooth: Bluetooth struggles with noise. Try Brown noise, raise Softness, keep the phone close, or use a wired headset or the speaker.
Sound stops with the screen off: Settings → Apps → AuraSound → Battery → Unrestricted.
Backup: export your presets now and then, because clearing app data deletes them.
Updates: open About and tap Check for updates.
