Routes live microphone input through a phone to external speakers, Bluetooth devices, or headphones, offering a portable public address workflow for classroom, tour, and event use. Shoutly: Megaphone Mic Speaker, from TheYourList, runs on Android and keeps audio processing local to the device. The app targets teachers, guides, and event organisers who need a handheld amplification tool that operates while the device is locked and supports both live voice and queued announcements.

How the tool handles live amplification and creative voice effects

The app sends the phone microphone output to external audio in real time and applies digital effects, so you can pick between Megaphone, Walkie-Talkie, AM Radio, and Robot modes while speaking. It includes microphone gain up to +24 dB and real-time level meters, which lets a speaker raise presence without external mixers. The soundboard supplies sirens and applause for stage cues, and message recording plus automated repetition helps with timed announcements.

What audio outputs and protection it supports

Shoutly routes audio to Bluetooth speakers, wired 3.5mm outputs, or the phone speaker and continues running in the background when the screen is off. It ships with Feedback Guard and Echo Cancellation that detect howling tones and notch them out, reducing live feedback risk during close-mic setups. The app processes all audio locally, so voice data is not uploaded to external servers.

Performance, workflow, and who can use it effectively

The app targets practical, on-the-move amplification: low-latency mic-to-speaker routing and background operation suit tour guides and teachers who need hands-free use. Karaoke and adjustable reverb modes let casual performers mix music with voice; the music volume can lower automatically when you speak. Event organisers gain automated repeating announcements for queues, while users who need detailed audio mixing may find the single-device approach less suited to complex soundboard rigs.

A practical handheld PA for field use, with a clear target

The app is a purposeful tool for educators, guides, and small-event staff who need immediate, portable amplification and in-device effects without cloud processing. Although it does not replace multi-channel mixers or dedicated PA consoles for large venues, it offers a compact, background-capable way to address crowds, cue effects, and replay announcements, making it appropriate for small to medium, mobile public-address tasks.
