Easy Quality Control Checks


In a playlist directory or chosen files, QCBox analyzes the relevant media data. Basic checks include checking for correct stream length continuity (no missing or overlapping frames), frozen or empty frames, and audio tests including measurement of loudness, phase and audio quality. Test results are stored on AirBox in a metadata file that contains the media file. The metadata file is tested and, based on the software parameters, the AirBox playout can be programmed to skip the file, show an alert before playing the file or play the file. In addition QCBox's loudness control data can be used to change the audio playback settings automatically.
