More often than not, cost-effective unskilled employees will have to perform the ingest process, which provides a lot of challenges to the process definition. One thing is editing the final archive file, which may result in a badly cut audio signal.

For this reason QUADRIGA•Audio provides an All-time Undo feature in order to redo the archive soundfile trim operation at any given time, without having to manage backup copies or, worst case, having to redo the ingest recording.

This is achieved by storing short audio fragments, before and after the proper sound modulation, invisibly for standard media players in a private chunk of the sealed BWF/MBWF file. This allows for example to repair a destroyed onset even years later when the defect finally gets detected. And this is the reason why QUADRIGA•Audio provides a "temporary" and a "sealed" file format.
