MicCast: Phone to Speaker

Turn your phone into a live microphone.

MicCast plays your voice, live, through the speaker you choose — a Bluetooth speaker, a wired or AUX headset, a USB audio device, or your phone's own speaker. Tap one button and start talking. It's the simple phone‑microphone‑to‑speaker tool for anyone who needs to be heard.

Perfect for:
• Public announcements and events
• Classroom and small‑group voice amplification
• Meetings and family gatherings
• Karaoke nights
• Testing your Bluetooth or wired speakers

What you can do:
• One big, clear microphone button — go live in seconds
• Choose your output: Bluetooth microphone, wired, USB, or phone speaker
• Voice presets — Announcement, Classroom, Karaoke, and Custom
• Adjust mic gain, mute instantly, and see a live input meter
• Keep talking in the background with a handy Stop/Mute notification
• Guided Sound Check to test safely before you go live
• Diagnostics screen with your audio details and buffer modes

Honest about delay: some latency is normal, and Bluetooth adds the most — it depends on your phone, speaker, and codec, and no app can remove it. For the fastest response, use a wired, USB, or the phone speaker, and try the "Lower delay" mode.

Private by design: your audio is processed live on your device. MicCast does not record, save, or upload your microphone audio. Ever.

MicCast is a voice‑amplifier and loudspeaker utility. It is not a hearing aid and not a medical or emergency device.
