About this course

This course teaches the complete audio-restoration pipeline a working editor runs on damaged dialogue and music, from diagnosing a problem on the spectrogram to applying the right repair module in the right order. You will use named tools including iZotope RX, Audacity, and the Youlean Loudness Meter, and the specific numbers that separate clean repair from over-processed, watery artifacts. By the end you can fix 50/60 Hz hum, remove clicks and mouth noise, recover clipped peaks, and reduce broadband noise without destroying the source.
