The De-hum audio plug-in and module in iZotope RX automatically identifies the base frequency of unwanted hum and precisely removes it from the recording along with harmonics, ensuring a clean overall sound without electrical interference. For more complex hum and buzz removal, the module also automatically recommends when to use De-noise instead, so you'll always have the best tool at hand for the job. Use Adaptive mode to remove hum that changes in frequency over time.
