Why Log Audio?
Broadcasting to general public implies responsibility which may need you to store all the recordings of your Radio Station for later referral in case of any queries from the Authorities. Normally recording of Audio in Audio Tapes will suffice the Compliance requirements but the newer restrictions in some countries require you to save the audio recording in a format thats easy to retrive when needed.
Audio recordings saved as Videos with the Time Stamps overlaid help retrieve the content quickly!
