CodecCast TX — Professional Live Audio Broadcasting Turn your iPhone or iPad into a professional-grade audio transmitter. CodecCast-TX streams high-quality stereo audio in real time to CodecCast-RX receivers, giving broadcasters, event crews, and field reporters a fast, reliable way to go live — without heavy hardware. Built around a broadcast-console interface, CodecCast-TX keeps the controls you actually need — input levels, link status, and on-air state — clear and immediate. KEY FEATURES High-quality stereo streaming Send full stereo audio in real time using a music-optimized codec. Connect a USB audio interface or wired headset for true left/right capture; mono sources are sent as clean dual-mono. Flexible audio input Automatic input selection prioritizes USB, then wired, then Bluetooth, then the built-in mic — or pick a device manually. Live input metering with professional PPM-style ballistics lets you set levels with confidence. Free 3-minute test Check your audio and connection with a free 3-minute test broadcast before you commit to going live. Channels and instant QR join Create up to 99 named channels. Show a QR code and listeners join in seconds — no logins, no setup. A separate ADD-TX QR lets multiple transmitters broadcast into the same channel together (GROUP CAST). See who's connected View the receivers and transmitters on each channel, complete with organization name, device name, and online status. Reference tone and instant mute Send a 1 kHz, -18 dBFS line-up tone for level alignment, and mute instantly whenever you need to. Connection monitoring Keep an eye on server link status, latency, packet loss, jitter, and bitrate, and run a line-quality check before you go on air. Broadcast time that stays yours Broadcasting uses broadcast time (minutes). Buy additional minutes anytime as one-time in-app purchases — no subscriptions. Your balance is tied to your installation and can be moved to a new device by QR transfer, or restored with your Apple ID. Set your identity Name your organization and device so receivers always know exactly who's on air. HOW IT WORKS 1. Open CodecCast-TX and create a channel. 2.
