How OpenedMic Works

OpenedMic is a browser-based live audio platform. The broadcaster opens a room in a supported browser with no installation or account. Listeners join by scanning a QR code or opening a link. Media uses WebRTC, with a direct peer path where available and an encrypted relay when the network requires one.

No app install No listener account Host-controlled

Three Steps

1
Open a Room
Go to openedmic.com/app in a supported browser. Enter your name, choose a broadcast mode such as Lecture, Tour, Ceremony, or Podcast, then create the room. No account is needed.
2
Share the QR or Link
The room displays a QR code and join link. Show the QR on screen, send the link, or use the built-in share action. Listeners open the room in a supported browser on a connected device.
3
Go Live
Press MIC ON to start the broadcast. Audio is processed in the browser and sent through each connected listener's WebRTC path. Camera, supported screen sharing, and media playback remain under broadcaster control.

Two Roles

BROADCASTER
  • Opens the room from openedmic.com/app
  • Controls audio, video, and media sources
  • Shares QR code or link with the audience
  • Can enable or disable group chat
  • Can kick or block disruptive listeners
  • Can record locally to their device
LISTENER
  • Scans a QR code or opens the join link
  • Joins from a supported browser with no app required
  • Hears processed audio in real time
  • Selects an available audio output and controls playback volume
  • Can send emoji reactions
  • Can participate in chat if enabled

Listeners receive only by default. One listener at a time may request the Approved Guest Mic, and the broadcaster decides whether to approve. Listeners cannot enable a camera or share their screen. OpenedMic is a controlled live broadcast, not an open meeting or video-call tool.

Approved Guest Mic

One listener at a time may request to speak by tapping Ask to speak. The broadcaster sees the request with the listener's name and avatar, and chooses Approve or Deny. After approval, the listener's browser asks for microphone permission. Once permission is granted and the audio path is ready, the guest is live and the broadcaster's mix includes the guest's voice. All other listeners hear the approved guest as part of the broadcast.

The broadcaster keeps full control of the room: a guest volume slider, a mute/unmute toggle, and an End Guest button. The broadcaster's own voice always takes priority. A built-in ducker briefly lowers the guest's level whenever the broadcaster speaks, then restores it. The guest mic is not an open conference call; it is controlled live participation, suitable for a question, a remark, a brief blessing, or a panel response.

What you need as a guest: a supported modern browser with microphone access. The page must be served over HTTPS for mobile browsers to grant that permission. No account, app installation, or registration is required.

Audio Processing

OpenedMic processes audio in the browser using the Web Audio API before transmission. Each broadcast mode applies a documented signal-chain preset with filters, EQ, compression, gating, and gain settings. Results vary with the microphone, device, browser, room, and network.

Available broadcast modes include Lecture for voice-focused filtering, Outdoor Tour with a stronger gate, Music / DJ for a wider range, Ceremony with lighter processing, Podcast with a defined voice EQ and compression preset, Multi-Speaker for stereo output, and Custom for manual controls.

Media Transport

WebRTC carries audio and video in supported browsers. It uses a direct media path when the network permits one. Otherwise, the connection uses an encrypted TURN relay. OpenedMic does not store the live media on its servers.

Up to 200 listeners can join a single room simultaneously. Rooms are created and destroyed per session - they do not persist after the broadcast ends.
