OnAirScreen 1.0.0 — IBC 2026

OnAirScreen 1.0.0 is out. After years of 0.9 in real studios — feature requests, betas, and the long stretch from an on-air lamp to a full studio display — this is version 1.0.0.

It lands as IBC opens in Amsterdam, 11–14 September. If you already run 0.9.8, you know the web UI, MQTT, and the top-of-hour countdown. 1.0.0 is the release that puts loudness, AoIP, analog clocks, mixer GPI, and Stream Deck on that same screen.

OnAirScreen 1.0.0 main view: stereo meters, mic timer, ON AIR LED, digital clock, weather widget, and NOW line — OnAirScreen 1.0.0 — meters, ON AIR, clock, AIR timers, and weather.

Loudness and audio sources

Studios wanted meters on the on-air display. 1.0.0 has them: stereo L/R in dBFS, dBTP, or BBC PPM, and programme LUFS to EBU R128 — momentary, short-term, and gated I+LRA when you start a session. Show L/R, LUFS, or both.

The feed can be a local sound card, or Axia Livewire or AES67 compatible (SAP or a pasted SDP). If the level is too high, TOO LOUD appears on screen or an LED comes on. If the signal drops out, silence detection can show a WARN message, trigger MQTT, or send an HTTP GET.

A clock that matches the room

The clock on screen can use local time, NTP, software PTPv2, or SMPTE LTC.

Choose a face in Settings. The rest of the display stays put — LEDs, timers, meters, branding. LED digits, a classic analog, numerals, a white studio face, a railway station clock, or 24-hour cream with a ticking or smooth second hand.

OnAirScreen with the digital LED clock, orange seconds ring, meters, ON AIR, and weather — Digital — LED digits and a seconds ring.

OnAirScreen with the classic analog clock: white ticks and hands, no numerals — Analog — ticks and hands, no numerals.

OnAirScreen with Analog Numbers: black analog face with numerals 1–12 — Analog Numbers — 1–12 on the classic face.

OnAirScreen with Analog Studio: white face, black ticks, and numerals 1–12 — Analog Studio — white face with black 1–12.

OnAirScreen with Analog Railway: white station clock and a red ring second hand — Analog Railway — station clock, red ring second hand.

OnAirScreen with Analog 24h: cream face, black 1–12 and red 13–24 — Analog 24h — cream face, 1–12 and 13–24.

From the desk

LEDs, AIR timers, NOW/NEXT, loudness, and settings from where you sit: in the browser, in Bitfocus Companion, or on the Stream Deck.

Elgato Stream Deck with OAS keys in a radio studio: MIC, ON AIR, LUFS, and timers, with mixer and on-air lamp in the background — Stream Deck at the desk — MIC, ON AIR, LUFS, and timers.

OnAirScreen Remote Control in the browser: live status for LEDs, AIR timers, silence, loudness I+LRA, and NOW/NEXT plus control panels and settings — Web UI in the browser — live status, control, and settings.

Bitfocus Companion Buttons view with the OAS page: MIC, timer, and ON AIR keys plus LUFS readout — Bitfocus Companion — live times, LUFS, and LED keys.

Raspberry Pi: GPIO and an SD image

Behind the studio monitor, a Raspberry Pi is still the compact way to run OnAirScreen. In 1.0.0 the mixer GPI can light the LEDs and start the AIR timers — up to eight inputs. GPIO is included with the Raspberry Pi edition and the SD image.

Flash the image, plug in, go on air.

Meet at IBC

I do not have a stand at IBC. I will be at the RAI in Amsterdam from 11 to 14 September. If you want to see 1.0.0, ask about using it in your studio, or just say hello — write me.

Upgrade notes

Your settings stay compatible — no migration. Shop customers update with the Update Key from the customer portal.

Saved settings keep working after the upgrade
Web UI stays on the HTTP port (default 8010); settings can sit behind a PIN
MQTT stays off until you enable it. Home Assistant picks up the new loudness and silence entities

Ready-to-run builds for Windows, macOS, Linux, and Raspberry Pi — from €23 — are in the OnAirScreen shop. The SD image ships with OnAirScreen already installed.

Thank you

1.0.0 is for everyone who ran the 0.9 builds on air, filed bugs, tested betas, and told me what the screen still needed. Years of that work is in this version.

Thank you — and happy broadcasting.
