Audio

ID	Name	Event Error	Description
61	No Audio	No Audio	This event is triggered if one of the following occurs: The compressed Audio content is not encoded/present. Audio cannot be decoded or produced by the Decoder. There is no audio PID in the TS, or on the HLS or MPEG-DASH stream.
62	Audio Silence	Audio Silence	Audio Silence is detected for a longer time than the configured thresholds. The message specifies the relevant PID. Silence is calculated as 0 - 70 (dB) for all the Audio Silence related Events.
63	Audio Phase	Audio Phase Error	The audio phase error detected between Stereo or 5.1 content for a longer time than the configured threshold. The message specifies the relevant PID.
73	True-Peak Audio Level above X dBTP	Audio Peak	The audio peak detected is higher than configured. The default threshold defines the distance from max sample value in dBTP units according to ITU-1770-2, EBU-R-128 (3341, 3342, 3343, 3344) standards. The message specifies the relevant PID.
74	Short Term (3 seconds) Audio Level above X LUFS	3s Audio Level	The audio detected short-term loudness above the configured value (calculated on a 3-second interval). The message specifies the relevant PID. Loudness value is measured in LUFS units.
86	Audio Bitrate, Max Threshold	Audio BR above Max	The audio bitrate detected is greater than the configured maximum threshold.
87	Audio Bitrate, Min Threshold	Audio BR below Min	The audio bitrate detected is smaller than the configured minimum threshold.
107	Detect Mono Audio (on streams with 2 or more channels)	Audio Mono	Mono audio detecting operates on Stereo or above programs. Audio level measurement of the differences between the left and the right channels is done. For the stereo channel, there should be some difference in amplitude. The event will trigger when Mono audio content is detected on the Stereo channel for a duration exceeding the configured threshold.
125	Detect Audio Codec Mismatch	Audio Codec Mismatch	The event will trigger when the detected audio encoding does not match the configured/expected CODEC type (MPEG, AAC, HE-AAC...).
126	Audio Silence on Left Channel	Left Audio Silence	Silence detected only on the left channel.
127	Audio Silence on Right Channel	Right Audio Silence	Silence detected only on the right channel.
128	Detect Audio Channels Mismatch	Audio Channels Mismatch	This event is triggered when there is a mismatch in the audio program between the actual and expected value for Stereo, Mono, 5.1.
141	Audio Silence on all Channels (Mono, Stereo, or 5.1)	Audio Silence (L+R)	Audio Silence is detected on all Audio program channels. It can be on Mono, Stereo, or 5.1 channels.
143	Audio Silence on Surround Channels	Surround Silence	Silence detected on audio surround channels.
211	Audio Level below X LUFS for 60 Seconds (or channel defined time)	Low Audio	The audio level is below the configured minimum level for 60 seconds or more.
255	Audio language descriptor mismatch	Audio Lang Mismatch	If the current and expected Audio Descriptors PID's values are different, this event is triggered.
258	Monitor dialnorm vs expected static configured value	Dialnorm Mismatch	Dialnorm is only relevant for Dolby content. The value ranges between -1 to -31 and provides an indication of the level of the dialogue from the Audio content feed. It's basically the number displayed on the audio bars in yellow. The event will trigger when the detected value is different than the expected static configured value.
340	Audio level above X LUFS for 60 seconds (or channel defined time)	Loud Audio	It is triggered if the Audio level is above X LUFS for more than 60 seconds or as defined in the channel.
