Keep Audio Alive Ultimate

😤 Sound familiar?

You're practicing with your favorite music app, the song ends… and a few seconds later an ugly HUM 🐝 starts buzzing from your speaker. Or you hit play again and hear a nasty POP 💥. Or your Bluetooth speaker simply switches itself off 😴 because it "heard nothing" for a while.

That's not your speaker's fault. Android puts the audio output to sleep a few seconds after playback stops, and many DACs, amplifiers and speakers really don't like that.

👉 If that has ever annoyed you, Keep Audio Alive is your app!

✨ HOW IT WORKS
Keep Audio Alive plays a continuous, inaudible signal in the background, so the audio output never goes to sleep. Your music app keeps playing exactly as before: Keep Audio Alive never pauses or interrupts it.

✅ Works with any music or audio app (practice apps, streaming, YouTube, podcasts…)
✅ USB-C DAC 🎛️, headphone / line output 🎧 and Bluetooth speakers 🔵
✅ No more standby hum, clicks or pops
✅ No more cut-off first second when playback starts again

🔵 BLUETOOTH KEEP-ALIVE
Some Bluetooth speakers turn themselves off after a few minutes without a signal. Try the near-silent noise signal first: many speakers stay on with it. If yours still switches off, Keep Audio Alive can send a short, very deep 30 Hz pulse at regular intervals.
- Pulse every 5, 10 or 30 seconds, or 1, 3, 5 or 10 minutes (start with 3 minutes or more; short intervals only if needed)
- Low / Medium / High level
- Test button to check it on your own speaker

⏱️ TIMER
Run it for 15 minutes free, or choose 30 minutes up to 5 hours, or until you stop it (Pro). The notification always shows the countdown and a Stop button.

🆓 FREE AND PRO
Free: the 15-minute timer, both signal modes and the Bluetooth pulse, so you can try all the important features. Pro (one-time purchase, no subscription): all timers, auto start after boot and future Pro features.

🎚️ TWO SIGNAL MODES
- Digital silence: pure digital zero
- Near-silent noise (about −86 dBFS): for DACs that mute or power down on pure silence

📱 SMART PHONE SETTINGS
Phone makers love to stop background apps. Keep Audio Alive recognizes your phone (Samsung, Xiaomi, Huawei/Honor, Oppo/Realme/OnePlus, Vivo…) and shows exactly which settings to change, with buttons that jump to the right page.

🔁 AUTO START AFTER BOOT (Pro)
Optional: after a restart, Keep Audio Alive starts by itself with your saved settings. Off by default.

🔋 LIGHT ON RESOURCES
Practically no CPU use: the system just repeats a 1-second buffer. The battery cost is about the same as playing something very quietly. The Bluetooth pulse adds a little load only while it is switched on.

🔒 PRIVACY
No ads, no account, no tracking. Your settings stay on your phone. The only network use is the optional Pro purchase, handled by Google Play.

ℹ️ GOOD TO KNOW
If you hear hum even while music is playing (often while charging), that's a ground loop, not standby. A ground loop isolator fixes that; no app can.

🔐 PERMISSIONS
- Foreground service (media playback / special use): plays the inaudible signal while you use other apps. Always visible as a notification with a Stop button.
- Notifications: shows the countdown and the Stop button.
- Run at startup: only used if you turn on "Auto start on boot". Off by default.
- Battery optimization exemption (optional): lets you allow unrestricted battery use so the phone doesn't stop the app.
- Internet: only for the optional Pro purchase.

🎶 Keep the music flowing, not the hum!
