Post Production And Broadcast: Audio Loudness Correction On Your File Based Content With Cerify

CerifyCerify can now go beyond audio checks by automatically correcting audio loudness in the audio essence(s). Working with a variety of container types, audio level correction can be applied to the entire essence duration, and can be triggered by non-compliance to EBU R128 or ITU-1770-3 Audio Loudness Recommendations. Automated loudness correction works for Dolby Digital, Dolby Digital Plus, Dolby-E, PCM audio formats. Watch this product demo video to find out more.
