Description
This Test is about the reference sampling clock frequency of the audio essence.

Typical values are 32, 44.1 and 48 kHz.

Typical notations in user interfaces are 48000/1, 48000, 48 kHz, 48.0 kHz.
Definition
Used in Checks, the system shall check whether the sampling rate of the audio track(s) indicated in the wrapper metadata matches the expected one specified in the input. Optionally it may report the read out values.

Used in Reports, the system shall read out the sampling rate of the audio track(s) declared in the wrapper metadata and report it.

Examples
  • Input: "Audio Sample Rate Expected" = 48.0 kHz
    Output: "Check Result" = false
    Output: "Audio Sample Rate Value" = 44.1 kHz

    Remark: Used as a Check.


  • Input: none
    Output: "Audio Sample Rate Value" = 44.1 kHz

    Remark: Used as a Report.

Remarks
Remarks
This Test is a readout only and includes no measurement.

This Test is about the metadata "Audio sampling rate" and not the metadata "Sample Rate" which can also be found in the Generic Sound Essence Descriptor.

This metadata element is best effort metadata. If the detected value is a distinguished value, the search shall be continued until a non distinguished value is found. If no non distinguished value is found, the distinguished value shall be used. If the metadata appears more than once in the file, the results can be output using the implicit Track and/or WrapperLocator output attributes.

This information is not available in all wrapper formats.
