Frequently Asked Questions

Can any Android phone be used as a microphone?

Yes, any Android phone with a built-in microphone can work as a voice amplifier. The app uses your phone's existing hardware to capture audio and outputs it through connected speakers. Most modern Android phones have quality microphones sufficient for presentations and teaching.

What speakers work best with a microphone app?

Bluetooth speakers are the most convenient option for wireless setups. For larger venues, you can connect to professional sound systems via Bluetooth or wired AUX cable. Choose speakers with at least 10-20 watts output for small rooms, and 50+ watts for larger spaces or outdoor events.

How do I reduce feedback and echo?

To prevent feedback, keep the speaker away from the phone's microphone—at least 6 feet or more depending on speaker volume. Use the app's noise reduction feature to filter background noise. Positioning yourself between the phone and speaker also helps reduce echo and feedback loops.
