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
Many Bluetooth speakers turn themselves off after a few minutes without a signal, and silence doesn't count. Keep Audio Alive can send a short, very deep 30 Hz pulse at regular intervals, so your speaker stays on.
- Pulse every 1, 3, 5 or 10 minutes
- Low / Medium / High level
- Test button to check it on your own speaker

⏱️ TIMER
Run it until you stop it, or let it stop by itself after 15 to 300 minutes. The notification always shows the countdown and a Stop button.

🎚️ 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.

🔁 START REMINDER AFTER BOOT
After a restart, a notification offers to start Keep Audio Alive with one tap.

🔋 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.

🔒 PRIVACY
No ads, no account, no data collection, no network connections. Your settings stay on your phone.

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): plays the inaudible signal while you use other apps. Always visible as a notification with a Stop button.
- Notifications: shows the countdown, the Stop button and the optional start reminder after a reboot.
- Run at startup: only used for the optional start reminder. Nothing starts automatically.

🎶 Keep the music flowing, not the hum!
