The professional loudness meter for broadcast, post and live shows, EBU R128 / ITU-R BS.1770-4 and BS.1771 compliant, with AI-powered speech analysis.
Whether you are mixing a news show, signing off an audio drama master or running a live programme, the loudness METER PRO does not just tell you whether your level is right. It tells you how intelligible your speech actually sounds, how your programme is shaping up to broadcast end, and whether your dynamics stay inside the allowed corridor. All in realtime, in one clear interface.
Momentary, Short-Term and Integrated Loudness with correct 400 ms gating engine at 75% overlap. Power-domain in double precision, no LUFS drift over hours-long programmes. LRA per EBU Tech 3342.
Inter-sample peak detection with 4x polyphase FIR filter. Spot-on even at inter-sample peaks, compatible with every R128 limiter. 200 ms update rate, smooth without flicker.
Silero VAD v5 reliably detects speech even under music. wespeaker ResNet34-LM with speaker-lock auto-detects speaker changes. Traffic-light: Good · Fair · Poor, tells you whether your speech reaches the listener intelligibly, before the phone rings.
Predicts Integrated Loudness and LRA at programme end based on the running history. Programme-duration panel with remaining time, 4-field banner with loudness trend, LRA trend and headroom.
PPM bars in broadcast scale (-59...-5) with cyan/green/red zones, vectorscope with correlation, FFT spectrum, loudness radar and three histograms (Loudness, LRA, R128 Gating). Familiar look for seasoned engineers.
All / Live / Analytics, three modes for every situation. Batch mode for whole folders with CSV and multi-page PDF reports. MIDI Learn, Bluetooth MIDI pairing and GPI for the gallery.
The same DSP runs on every platform. Feature scope scales with the use case, from a mobile quick-check to full production.
