title: Audio Quality Assurance: An Application of Cross Correlation
creators: Bolette Ammitzboll Jurik Jesper Sindahl Nielsen
abstract: We describe algorithms for automated quality assurance on content of audio files in context of preservation actions and access. The algorithms use cross correlation to compare the sound waves. They are used to do overlap analysis in an access scenario, where preserved radio broadcasts are used in research and annotated. They have been applied in a mi- gration scenario, where radio broadcasts are to be migrated for long term preservation. This work was partially supported by the SCAPE Project.
  The SCAPE project is co-funded by the European Union under FP7 ICT-2009.4.1 (Grant Agreement number 270137).
