Audio Encoder Statistics
The following table lists the Audio Encoder statistics:
Audio Encoder Statistic | Description/Values |
|---|---|
Status | The current operating status of the encoder, indicated by the status icon, either:
|
| Encoded Frames | Number of encoded frames. |
Encoded Bytes | Number of encoded bytes. |
Encoded Bitrate | The audio bitrate used for the encoder (in kbps). Note When using 16-bit Pass-Through, this statistic may not match the configured bitrate. In this mode, the configured audio encoder bitrate is ignored; instead, the bitrate is a fixed number determined by the number of channel pairs carried. |
| Encoded Framerate | The current rate of encoded frames per second (FPS). |
Encoder Errors | Number of audio encoding errors. |
Encoder PTS | The current encoder Presentation Time Stamp (PTS) based on a 90 kHz clock: e.g., 0x138a56483 |
STC Source Interface | (only available when State is Encoding) The audio input from which the audio STC (System Time Clock) is derived: either BNC-1, BNC-2, BNC-3 or BNC-4. |
Maximum Sample Value | The maximum sample value for each channel pair being processed. Range: 0-32767 (0-100%). |
| Maximum VU Level | A sample of the maximum volume level (in dB) per channel. Range: -80 dB to 0 dB |
| Last Statistics Reset | The time elapsed since the last statistics reset. |
Reset | Click to reset the Audio Encoder statistics. |
| Linear PCM Audio Statistics | Description/Values |
| Pass-Through Type | The pass-through type detected in the audio source. Values can be: PCM, or, non-PCM |
| Detected Algorithm | The audio codec algorithm detected from the audio source: e.g., AC-3. |
| Detected Samplerate | The sample rate (in kHz) of the incoming audio. Values can be: 16 kHz or 48 kHz. |
| Detected Bit Depth | The number of bits detected per sample. Values can be: 16, 20, or 24 bits. Note Currently, only 16 bit Bit Depth is supported. Reported Bit Depths of 20 or 24 bits indicate error conditions. |
