Dobbin System For QC and Derivative Creation

CBC uses a DAT ingest system based on 4mm data drives, rather than standard DAT players. The main advantage of this system is that it can ingest at double speed. However, this system creates "data" files that must be converted to wave files by using a background batch processor-type application. The disadvantage of the system is that - like most current DAT transfers - they are susceptible to drop-outs from media problems and/or transport tracking issues. To some extent, these issues are amplified due to the fact that the transport is moving twice as fast as a standard DAT tape. Additionally, the system cannot use the DAT error correction facilities since the system handles the tapes as "data" tapes - not DAT tapes.  For problem tapes CBC uses standard DAT ingest via AES/EBU.

 CBC employs 4 parallel data-ingest platforms and since the process is at double-speed there is no "human" monitoring. The requirement for some automated quality control after ingest was required to keep the workflow moving efficiently or it would quickly bottle-neck with human spot checking. The numbers of errors are potentially high and many could be missed by spot checks or alarms on the ingest platform. A custom workflow to test for digital errors and data corruptions was created for the CBC. If a wave file passed all QC tests, a Dalet style mp2 file is created and uploaded to the Dalet Radiola system. Here is what the workflow looks like.

Dobbin and Cube-WorkflowSystem For Custom QC Workflows for Post Production

Since 1984, Chace has earned a reputation as a world leader in the field of soundtrack restoration, preservation, and 5.1 / 7.1 mixing. Chace Audio by Deluxe provides complete audio post production services, with a dedicated team of specialists in both historic material and cutting edge technology.

An early adopter of Cube-Tec restoration technology, Chace also uses Dobbin and Cube-Workflow for custom quality control processes in their post-production facility. The requirement for this project was to provide specific automated QC processes for film post-production projects. A number of QC processes were required:

  • Digital and analog file corruptions.
  • Automated extraction of audio streams to BWF from Pro-Res AV files.
  • Optical sound track QC using Psycho-acoustic correlation between master and transfers.
  • CALM based Loudness Correction.
  • Automated camera/gen noise removal from dailies.

The workflows required projects to be started from the Chace 4D database, triggered from XML metadata which was ingest to Cube-Worflow. Project management and process control was through Cube-Worflow with final results exported back to the 4D database upon completion.  A sample worklfow is below and an early workflow power-point is on the link:

Dobbin System For QC Workflows and Derivatives

Library and Archives Canada preserves and makes accessible the documentary heritage of Canada. It also serves as the continuing memory of the Government of Canada and its institutions. This heritage includes publications, archival records, sound and audio-visual materials, photographs, artworks, and electronic documents.

Libraries and Archives Canada uses Dobbin to perform ingest QC for both digital and analog defects.  If the QC tests pass, then files are prepared with an File Security Code and a SHA-1 hash for the master preservation file (deep archive) - as well as creating mp3 derivatives for access use.

QUADRIGA Cassette Transfer System and Dobbin System For QC Workflows and Derivatives

The Baylor University Archives at The Texas Collection serves as the secure repository for Baylor University records. Its principal function is to collect, preserve, and provide appropriate access to records of enduring value related to the history of Baylor University. In addition, The Texas Collection is a special library, archival research center, and the University Archive that collects, preserves, and provides access to materials documenting the history, heritage and culture of Texas for the Baylor community and the public

In 2010 Baylor Libraries/Archives required a high-speed cassette ingest platform for approximately 6000 hours of spoken word plus secondary use for other library collections. A QUADRIGA/CTS system with the Otari dual-deck double-speed cassette player was procured for this project. Two cassettes are ingested at double-speed with both A/B directions in a single pass. This results in an overall throughput of 8x real-time. QUADRIGA creates all the metadata for Dobbin post processes to re-equalize, reverse flip and pitch/time correct audio files. A secure master preservation BWF is created as well as mp3 derivatives for access. See PDF's for workflow particulars.

QUADRIGA, Dobbin and Cube-Workflow Systems with DB integration

The National Archives and Records Administration (NARA) is an independent agency of the United States government charged with preserving and documenting government and historical records and with increasing public access to those documents, which comprise the National Archives. NARA is officially responsible for maintaining and publishing the legally authentic and authoritative copies of acts of Congress, presidential proclamations and executive orders, and federal regulations. The NARA also transmits votes of the Electoral College to Congress. NARA Archives II, near the University of Maryland, College Park campus takes care of audio visual records. Ingest of audio recordings for NARA are handled in-house and through third party service companies.

In order to handle the large amount of parallel ingest a Dobbin system was ordered to handle automated QC. All external materials are loaded into a basic "specifications test" workflow - to first ensure that materials follow NARAS digitization specifications. If the third party ingests pass, audio files move to the next in-house process - if they fail, the supervisor is notified and a report created so that the third party is notified for possible re-digitization. The QC algorithm tests for the following cases:
