Title |
IS20 Detect audio files with very bad sound quality |
Detailed description |
In a collection of mp3 files (20 Tbytes - 360.000 files) we have discovered files with very bad sound quality. Before ingesting everything into our DOMS we would like to be able to discover the bad files and potentially get those re-digitized from the original analogue media. |
Scalability Challenge |
Large amounts of data (20 Tbytes - 360.000 files). We foresee that the process needed to solve this will require both I/O intensive work as well as heavy use of CPU for analysing the actual content. |
