I don’t know if this is the place or not but here goes.
Can someone tell me how I can get rid of this horrible buzzing sound that you hear on this recording.
I tried playing around with different settings on the noise removal but it just made things worse.
Thanks a lot
Noise Removal isn’t the miracle drug that everyone wants it to be.
First recording? It sounds like you’re trying to do an interview across the room from the microphone. Even the big kids can’t do that.
Describe your microphone, computer, the room, etc.
Thanks for your fast reply.
I used a MacPro with the internal mic.
It was just a regular room and we sat about foot away from the mic.
Not such a good idea? But is there any hope to save it
(setf s (notch2 s 90 5)) (setf s (notch2 s 632 50)) (setf s (notch2 s 899 50)) (setf s (notch2 s 2898 20)) (setf s (notch2 s 12192 50)) (setq mysound s) (setq q 25) ; set the base Q for the filter (setq iter 44) ; set the number of iterations (setq freq 216.545) ; set base frequency ; start the DO loop (dotimes (i iter mysound) (setf mysound (notch2 mysound (* freq (1+ i)) (* q (1+ i)))) ) ;end of loop
It will look like this …
Select the section of audio with the buzz and apply Nyquist Prompt like an effect, and voilà the buzz has gone …
(the code only removes buzz, not hiss).
The picture is of my noise removal settings and the clip is post correction. Noise Removal works in two steps. The first step is to get a “profile” by drag-selecting a portion of the show with noise and no performance or other noises. The second pass is the actual reduction.
I uses the first second or two of your clip as profile.
I didn’t know MacPros came with internal mics.
On the newer laptops, there is a setting in Apple > System Preferences > Hardware > Sound > Input > Internal Microphone: [X] Use Ambient Noise Reduction.
Try that on a test interview before you get in a car for that President Obama meeting. Typically, that only works for voices. That’s not going to work if you record music.
Thanks a lot. It worked perfectly!!! (like magic)
I work with children (and teens) with learning difficulties so I like to record them in the beginning and then to record again a few months later to show them how much they improved.
In the old version (before the code you sent me) it was a little hard to hear now it’s great. Thanks a lot
p.s You are right I don’t have a MacPro but a MacBook!
