Hi
I have a video file that was probably originally recorded from TV.
There is a buzzing noise keeps drifting in and out.
Can anybody clean it up for me please?
Here is a sample ---> buzzing_sample

Why not use Uploads sub forum here instead of that joke site for the sample file?

Try Audacity's Noise Removal effect. I used the noise that occurs around the 11 second mark for the "noise profile". It didn't remove all of the noise and it introduces some artifacts that make it sound like a cell phone, but it might be an improvement.

When the nose is that bad, there is no perfect solution. So, it's best if you do it yourself and decide if the results are an improvement. Noise reduction usually works best when you have a slight constant background noise... i.e. It works best when you don't really need it.

Professionals STILL record in soundproof studios with really good equipment, because there is only so much you can do with software.

I believe that noise is either a VCR with HiFi tracks. There is a mismatch on the tracking and/or RF envelope because of tape guide alignment. If he still has the tape it can possibly be made better. Another possibility was RF interference of analog TV, ghosts / reflections / mis-adjusted AGC in the receiver. There is no fix for this except what can be done with noise reduction.

Processing the audio independently of the video may make it difficult to 'lay back' the audio when it's done.
