Mp3 To Wav Migrate QA CLI List Test
Created: 2012-11-05 11:43:51
Last updated: 2012-11-13 10:54:26
Migrates Mp3 files from input List to Wav files and performs QA. The QA steps include File Format Validation, Significant Property Comparison and migrationQA file content comparison (all CLI). As this is a Test workflow, the (very large) Wav files are deleted, and only the QA results and log files are saved for analysis. This workflow matches solution SO4 on the SCAPE opf wiki, see http://wiki.opf-labs.org/display/SP/SO4+Audio+mp3+to+wav+Migration+and+QA+Workflow
