Download Workflow

This workflow migrates an mp3 file to wav using a SCAPE ffmpeg web service. It validates the migrated file using a jhove2 SCAPE web service. It extracts and compares simple characteristic using an ffprobe SCAPE web service. This workflow matches solution (most of) SO4 on the SCAPE opf wiki, see http://wiki.opf-labs.org/display/SP/SO4+Audio+mp3+to+wav+Migration+and+QA+Workflow
