About this app

Bluetooth Mic to Speaker makes your phone the wireless microphone for a Bluetooth speaker. Pair a portable or party speaker, open the app and talk: your voice plays through the speaker in real time while you move around the room with the phone in your hand.

FINDS YOUR BLUETOOTH SPEAKER
• When a Bluetooth speaker is connected, Automatic sends your voice to it, no menus needed
• A status row shows the name of the connected Bluetooth speaker, so you always know where the sound is going
• No speaker yet? The app says so and opens Android's Bluetooth settings in one tap
• If the speaker drops out, the app falls back to Automatic; you can also pick the phone speaker or wired headphones

BUILT AROUND BLUETOOTH DELAY
• Bluetooth audio adds a short lag, often 0.1 to 0.3 seconds
• Keep the speaker a few metres in front of you so hearing your own voice late doesn't throw you off
• Feedback guard listens for the squeal that starts when the mic gets close to the speaker, cuts that tone and lowers the gain by 3 dB
• Even out volume keeps loud bursts from overloading a small speaker

SIMPLE CONTROLS
• Tap the big mic button to go live, or switch to hold-to-talk for short messages
• Gain slider from -6 to +24 dB, with in and out level meters
• Clear voice trims rumble and lifts speech
• Quick Settings tile to start without hunting for the app
• Runs with the screen off, with a notification and a Stop button
• Turns itself off, with a notice, when a phone call needs the mic

PREMIUM
• Echo and reverb: Echo, Karaoke, Hall and Stadium
• Voice effects: Megaphone, Walkie-talkie, Robot and Alien
• Sirens and chimes: Wail, Yelp, Hi-lo, Door chime and Alarm beep
• Unlimited sessions instead of 10 minutes, and no ads
• Monthly, yearly (3-day free trial) or a one-time lifetime unlock, via Google Play Billing

The free version is supported by ads. A rewarded ad gives you a 30-minute pass to all Premium features.

IDEAS
• Speak to a room from anywhere in it: club meetings, training sessions, small events
• Sing along through a party speaker
• Announcements in a garage, gym or backyard
• Kids' shows, games and talent nights

GETTING STARTED
1. Pair your Bluetooth speaker in Android settings
2. Open the app and allow the microphone
3. Check that the status row shows your speaker
4. Turn the speaker volume down, tap the mic and raise the gain slowly

SAFETY AND PRIVACY
Start quiet and keep the phone away from the speaker. Never use the app to listen in on people. Sound is processed on your phone and played live; it is never recorded or uploaded. Firebase Analytics and Crashlytics help us improve the app (you can turn them off in Settings), and ads in the free version use your advertising ID.
