It would be very interesting to have an automatic tool that checks the audio quality of a recording. And to plug such tool to the Record Wizard so that it prevents to upload recordings where an audio defect is detected (long blank before or after the recording, clicks, sudden increase or decrease of the volume, etc.)
We could also imagine that instead of blocking the upload, it tags the recording and alert the user to ask for a manual check.
