Guidelines: Performance impairments caused by interstitial errors
Audio-Visual Working Group

Interstitial errors consist of lost or altered samples within the recorded file, resulting in the loss of content and integrity. These errors--often very momentary--result from a failure in one or more of the interfaces that carry digital data, e.g., the handoff from the ADC to the digital audio workstation (DAW), and in the DAW's writing of the file to a storage medium. The first item linked below, titled Study Report, describes a 2012 field test carried out in three federal audio facilities, designed to identify occurrences of interstitial errors in the course of actual work. The second item, titled Appendixes and completed in 2012, provides background information as well as re-presenting sections from the consultant's initial 2011 report.
