    Any ideas on how to repair this audio track with IZotope RX ?
    Hi all, Here's "Little Wing" by Stevie Ray Vaughan : https://www.deezer.com/fr/track/848860 This track has a very disturbing hum all track long. You can notice it easily at 1:22-1:23, but it's there all song long. This hum appears on two separate audio equipments, so I guess the problem is not on my side but on the track's side. I have tried to remove it with IZotope RX 7, but I haven't suceeded at all. I guess it goes beyond my current skills. I have tried almost everything I could : hum removal, spectrum repair, and all sorts of things. After one hour, I just can't make it go away. I must be doing something wrong. Maybe I'm missing the hum's exact frequency, I don't know. Could somebody please point me in the right direction ? Thanks in advance !

    Hi - Of course the De-Hum module in RX should be the best way to go at it -- you might have to fine-tune the [base] hum frequency to get it to work effectively. The version of De-hum in RX 9 offers some improvements and might yield better results. The RX 9 De-hum also adds a Dynamic mode which iZotope suggests could potentially be more effective on problem tracks -- it has to Learn the hum in this mode, but it sounds like you might be able to use the more isolated section you mentioned [if the hum is isolated enough] to get De-hum to Learn the hum signature, and then apply it to the rest of the track.

    Thanks for your reply. I have spent 30 min again with the De-hum tool, focusing on the part around 1:22-1:23 where the hum can easily be heard, and I can't for the life of me find the frequencies of that damned hum. The auto detection gives me nothing useful, and I have tried a lot of frequencies and a lot of Q factors. I'm lost here. If somebody can either try on his own (I can provide the track or a part of it), or point me to another RX-focused forum... My point is that I don't want to bother anybody. I generally like to do things on my own, but this is the first time I'm completely lost with a given track. This is driving me mad, really.

    I guess if De-hum can't handle it you could try Spectral De-Noise -- that also has a Learn function and an Adaptive mode [at least in RX 9], which might help if the hum/buzz changes over the course of the song [iZotope suggests it for changing, shifting noise sources].
