CodecCast vs Redlined

**CodecCast RX — Professional Live Audio Receiving** Turn your iPhone or iPad into a professional-grade audio receiver. CodecCast-RX plays high-quality stereo audio streamed in real time from CodecCast-TX transmitters, giving event crews, interpreters' audiences, and monitoring staff a fast, reliable way to listen live — without heavy hardware. Built around a broadcast-console interface, CodecCast-RX keeps the controls you actually need — output levels, link status, and receive state — clear and immediate. **KEY FEATURES** *High-quality stereo reception* Receive full stereo audio in real time with a music-optimized codec, and hear the broadcast within about a second of the transmitter going on air. *Fully automatic reception* Join a channel once and CodecCast-RX does the rest: it connects, stands by, starts playing the moment the transmitter goes ON AIR, and returns to standby when the broadcast stops. Reception keeps playing with the screen locked. *Instant QR join* Scan the QR code shown on the transmitter and you're in — no logins, no setup. Your joined channels are kept in a list so you can switch between broadcasts with a tap. *See who's on air* The channel list shows each broadcaster's organization and device name, together with live status — ONAIR, ONLINE, or OFFLINE — refreshed every time you open it. *Flexible audio output* Audio follows your output automatically: USB audio interface, wired headphones, Bluetooth, or the built-in speaker. Live output metering with professional PPM-style ballistics shows exactly what you're feeding to your PA or headphones. *Reference tone and instant mute* Play a local 1 kHz, -18 dBFS line-up tone to check your speakers and level alignment — even before connecting — and mute the output instantly whenever you need to. *Connection monitoring* Keep an eye on server link status, latency, packet loss, jitter, and receive bitrate, and run a line-quality check before the show starts. *Try it free* Out of listening time? A free 30-second preview plays whenever a broadcast starts, so you can confirm everything works before you buy. *Listening time that stays yours* Listening uses listening time (minutes), consumed only while a broadcast is actually playing — standing by costs nothing. 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 broadcasters always know exactly who's listening. **HOW IT WORKS** 1. Ask the broadcaster to show their channel QR code in CodecCast-TX. 2. Open CodecCast-RX and scan it — you join and connect automatically. 3. When the transmitter goes ON AIR, audio starts playing instantly. 4. Switch channels anytime from your channel list. **WHO IT'S FOR** • Event staff, houses of worship, and conference attendees receiving a live audio feed • Interpretation and assistive-listening audiences • Engineers monitoring a remote or backup feed • Anyone who needs simple, high-quality, real-time audio reception **NO ACCOUNT REQUIRED** Get started right away. CodecCast RX doesn't ask you to create an account. CodecCast-RX is the receiver app. To broadcast, install CodecCast-TX on the transmitting device. Listening time is sold as consumable in-app purchases, and prices are shown in the app before you buy. Real-time performance depends on your network conditions.
