OriginalSpeedStandard Speed standard applied to the tape recorder during the digitisation of an open-reel tape. It can be one of the following values: 0.9375, 1.875, 3.75, 7.5, 15, 30. These values are in inch per seconds (ips). This field is optional.
OriginalEqualisationStandard Equalisation standard applied to the tape recorder during the digitisation of an open-reel tape. It can be one of the following values: “IEC”, “IEC1”, “IEC2”.

The notation refers to documents [16,17].

The association with OriginalSpeedStandard shall be compliant to the values indicated in [16,17].

This field is optional.
OriginalSamplingFrequency UUID [3] that identifies a Restoration.
Restorations List of restorations objects. Each object shall have at least the following fields: RestorationID, RestoredAudioFileURI, PreservationAudioFileStart, PreservationAudioFileEnd, AppliedSamplingFrequency, ReadingBackwards.
RestorationID UUID [7] that identifies a Restoration.
PreservationAudioFileStart Time Label indicating the instant of the Preservation Audio File when the restoration starts.
PreservationAudioFileEnd Time Label indicating the instant of the Preservation Audio File when the restoration ends.
RestoredAudioFileURI URI of a Restored Audio File.
ReadingBackwords Boolean value indicating if the audio signal direction has been inverted during the restoration process.
AppliedSpeedStandard Speed standard applied during the restoration process. It can be one of the following values: 0.9375, 1.875, 3.75, 7.5, 15, 30. These values are in inch per seconds (ips). This field is optional.
AppliedSamplingFrequency Specifies the sampling frequency of the Restored Audio File. This field is mandatory.
AppliedEqualisationStandard Equalisation standard applied during the restoration process. It can be one of the following values: “IEC”, “IEC1”, “IEC2”.

The notation refers to documents [16,17].

The association with AppliedSpeedStandard shall be compliant to the values indicated in [16,17].
