About this app
Your cell phone becomes the speaker's microphone.
Connect your cell phone to the speaker—via P2 cable, Bluetooth, or using the speaker itself—tap start and speak. What goes into the microphone comes out of the output you choose at that moment. No recording, no account, no internet.
Made for those who need the loudest voice right now: announcements at church, teachers in large rooms, sports courts, fairs, bazaars, karaoke, rehearsals, school presentations, tour guides.
HOW TO USE
1. Connect your cell phone to the speaker. A P2 cable is the best way.
2. Choose the output on the main screen.
3. Tap start and release the microphone when prompted.
4. Adjust the gain until the meter is in the green.
WHAT'S INSIDE
• Choice of output: cable, Bluetooth, or cell phone speaker, with the latency of each on the screen before you decide.
• Level meter with peak marker, to see when it's clipping instead of figuring it out by ear.
• Input gain from -12 dB to +24 dB, separate from output volume.
• One-touch mute, without ending the transmission.
• Feedback protection: detects the whistle before it grows and lowers the volume automatically.
• Delay measured on your device, with a button to measure again whenever you want.
• Three response settings (Minimum, Balanced, and Stable) for when the sound stutters on simpler cell phones.
• Stop by long press, so the microphone doesn't fall out mid-speech.
• Screen that doesn't turn off while the microphone is on air.
• Vibration when starting, stopping, and changing to mute, to confirm without looking.
ABOUT DELAY
Every audio path has delay. Here it appears on the screen instead of being hidden:
• P2 cable: less delay and no risk of feedback. It's the best option.
• Cell phone speaker: solves a short message, but the microphone listens to its own output. Keep the volume low and microphone protection on.
• Bluetooth: practical, but the delay is noticeable. It's good for notifications, not for singing along.
The app opens the fastest path the device accepts and shows which one it found. Different phones deliver different numbers, and the number that appears on the screen is yours.
WHAT THE APP DOESN'T DO
• It doesn't record anything. The audio plays and disappears.
• It doesn't send audio to the internet. It doesn't have an account, login, or server.
• It doesn't collect personal data.
• It doesn't replace a mixing console in professional production.
PERMISSION
Only one: microphone. And it's requested when you tap start, not when opening the app. Without it, there's nothing to amplify.
