Audio Monitoring

Real-time audio monitoring ensures quality, compliance, and seamless integration with TAG’s multiviewer and probing workflows.
What is it?

TAG audio monitoring is a set of configurable events and thresholds that continuously check program audio for issues like loss, silence, phase errors, loudness problems, bitrate/codec mismatches, and channel/language inconsistencies.

What can I do with it?

You can detect and get alerts on conditions such as no audio, silence on specific channels, mono on stereo, audio level too low or too high (LUFS, true-peak), incorrect bitrate or codec, wrong channel layout (Mono/Stereo/5.1), language descriptor mismatches, and Dolby dialnorm deviations.

What are the benefits?

It helps ensure audio quality and consistency, maintain standards-compliant loudness and metadata, quickly pinpoint and troubleshoot specific audio problems per PID/channel, and ultimately protect the viewer experience with less manual monitoring.

TAG’s audio monitoring capabilities provide automated, real-time oversight of program audio streams to ensure consistent quality and compliance. The system continuously checks for a wide range of audio issues, such as missing audio, prolonged silence, phase errors, excessive peaks, loudness deviations, bitrate anomalies, codec mismatches, and channel configuration errors. These checks are based on configurable thresholds and industry standards, allowing operators to tailor monitoring to their specific requirements and receive timely alerts when issues are detected.

By monitoring both overall and channel-specific audio characteristics, TAG helps broadcasters quickly identify and resolve problems that could impact the viewer experience. The platform’s detailed event reporting covers scenarios like mono audio on stereo streams, mismatched audio languages, and dialogue normalization discrepancies for Dolby content. This comprehensive approach ensures that audio quality is maintained across all channels and formats, supporting operational efficiency and regulatory compliance throughout the broadcast workflow.

FAQ

What are the audio monitoring specifications?

Audio codec :   MPEG2 / AAC / HE-AAC / A-52 / AES67

Dolby :  Dolby-D, Dolby-Plus, Dolby Atmos, Dolby-E

Audio channel mode :  1 / 1+1 / 2 / 5.1 / 8 / 16 / 7.1

Loudness monitoring :   EBU-R-128/ITU-1770-3/ATSC A/85

What kinds of audio problems can TAG catch?

It can automatically spot issues like no sound at all, long periods of silence, sound that’s too quiet or too loud, sound only on one side, the wrong audio format or number of channels, wrong language, or inconsistent dialogue levels.

How does TAG help me control volume and loudness levels?

TAG can watch for very short-term peaks (True-Peak Audio Level above X dBTP, ID 73, and 3s Audio Level above X LUFS, ID 74) as well as longer-term levels (Low Audio, ID 211, and Loud Audio, ID 340), so you can be alerted when audio is too quiet, too loud, or clipping and adjust your workflow or source accordingly.

How does TAG audio monitoring help day-to-day operations?

It reduces the need for constant manual listening, gives your team early warning when audio goes wrong, and makes it easier to pinpoint where the problem is, so operators can spend more time fixing issues and less time hunting for them.
