Sound Amplifier: Hear Louder

Sound Amplifier is a real-time sound amplifier that uses your Android device’s microphone to make nearby sounds louder and easier to hear. Connect your Bluetooth headphones or earbuds, place your phone near the sound source, such as in front of a TV or near a baby crib, and use Sound Amplifier to listen to nearby microphone audio as live audio streams directly from your phone microphone to your connected headphones or earbuds.

Use the app only where you have permission to listen, and obtain the consent of anyone involved when needed.

The Sound Amplifier app turns your Android phone into a microphone-based sound amplifier, TV listening device, and makeshift audio baby monitor. Place your phone near a television, speaker, baby crib area, or another sound source, then tap Listen to start streaming and continue listening through headphones.

The app captures nearby sound through your phone microphone and streams it to your connected Bluetooth headphones or earbuds. Keep your phone close to the sound source and stay within the supported Bluetooth connection range.

Use Sound Amplifier when you want to continue listening while moving around your home. Leave your phone near the television or another sound source and listen using your Bluetooth headphones or earbuds while you cook, clean, work, do laundry, or use the washroom, staying within Bluetooth connection range.

FOLLOW TV SHOWS THROUGH HEADPHONES
Sound Amplifier is useful when you are watching television but need to step away for some time. Place your Android phone near the TV, connect your Bluetooth headphones or earbuds, and continue to listen while you move around the house within Bluetooth connection range.

Use Sound Amplifier to hear TV audio and follow TV shows and dialogue through headphones.

LISTEN TO NEARBY MICROPHONE AUDIO
Sound Amplifier lets you place your phone near the sound source and listen through headphones within Bluetooth range. Your Android phone acts as a microphone for nearby sounds that captures live sound and sends it directly to your connected Bluetooth headphones or earbuds.

For clearer results, place your phone as close as safely possible to the television, speaker, baby crib area, or lecturer. The closer the microphone is to the sound, the clearer and louder the sound may be.

Connect your Bluetooth headphones or earbuds, tap Listen, and keep your phone near the sound source. You can then use Sound Amplifier to listen while remaining within the supported Bluetooth connection range.

AUDIO BABY MONITORING AT HOME
Sound Amplifier can also be used as a makeshift audio baby monitor at home. Place your Android phone safely near the baby’s crib area or inside the baby’s room, then listen for baby sounds using your connected Bluetooth headphones or earbuds.

Use Sound Amplifier to listen for crying, movement, soft noises, waking sounds, and other baby sounds through headphones within Bluetooth range while at home.

LIVE MICROPHONE AUDIO
Sound Amplifier captures sound through your Android phone microphone and streams the live audio directly to your connected Bluetooth headphones or earbuds. Your phone works like a microphone for nearby sounds, helping you hear sounds near the microphone in real time.

• Listen for sounds from your sleeping baby
• Continue following TV dialogue while moving around the house
