About this app

Turn your Android phone into a simple live microphone for a Bluetooth, AUX, USB or wired speaker.

Mic to Speaker sends your voice from the phone microphone directly to the selected audio output. Use it for classroom announcements, presentations, tour groups, church activities, small events, public speaking or any situation where you have a speaker but no microphone.

SIMPLE LIVE MICROPHONE

Connect a speaker, choose your input and output, then tap Start Mic. The current audio route is always visible, so you know exactly which microphone is being used and where your voice is going.

REAL-TIME NOISE REDUCTION

Make your voice clearer with on-device noise reduction. Choose between Off, Normal and Strong depending on your environment.

Noise reduction can help reduce steady background sounds such as fans, air conditioners and general environmental noise.

BLUETOOTH, AUX AND USB OUTPUT

Use your phone as a microphone with compatible:

• Bluetooth speakers
• AUX and wired audio devices
• USB audio devices
• Built-in phone speaker

For the lowest possible delay, use an AUX, USB or other wired connection. Bluetooth audio naturally has more latency depending on your phone and speaker.

MICROPHONE AND OUTPUT SELECTION

Mic to Speaker displays the active input and output devices.

When Android detects another compatible microphone, you can choose between the phone microphone, USB microphone or other available audio input.

ADJUSTABLE MIC GAIN

Quickly increase or decrease microphone gain with one simple control. A soft limiter helps reduce harsh clipping when the input level becomes too high.

FEEDBACK REDUCTION

The app includes basic echo and feedback protection where supported by the device.

For better results:

• Use an external speaker
• Keep the phone 1–2 meters away from the speaker
• Avoid pointing the speaker directly at the phone
• Reduce mic gain or speaker volume if feedback occurs

Because acoustic feedback depends on the room, speaker volume and device position, it cannot always be completely removed.

WORKS IN THE BACKGROUND

Keep the live microphone running when the screen turns off or when you switch to another app. A persistent Android notification lets you see that the microphone is active and stop it quickly.

PRIVATE AND OFFLINE

Your audio is processed in real time on your device.

• No audio uploads
• No voice recording
• No account required
• No cloud processing
• No subscription required

Mic to Speaker requires microphone permission to capture your voice. Notification permission is optional and is used only to display the live microphone status and Stop action.

DESIGNED FOR REAL-WORLD USE

Mic to Speaker is useful for:

• Classroom and school announcements
• Presentations and public speaking
• Tour guides and group activities
• Churches and community events
• Small meetings and temporary PA setups
• Practicing with a speaker
• Using a phone as a Bluetooth speaker microphone

Mic to Speaker is a portable PA microphone utility. It is not a hearing aid, medical device or professional zero-latency audio system.

Connect your speaker, tap Start Mic and speak.
