Hello
I have an audio that’s from the radio (not officially provided by the radio station) and when I put it on a video editor and add an audio visualizer, the peaks are okay at the sides but in the center it’s almost flat.
How can I balance that range, and without distorting the sound?
Thanks
The visualizer should be responding to the sound so any changes should be heard AND show-up in the visualization.
You can experiment with the Graphic EQ effect to adjust different frequency ranges. The Filter Curve EQ is more precise but not as easy to “play around” with.
“Distortion” usually means clipping (the most common kind of distortion). You’ll get digital clipping if you go over 0dBFS.
If you boost with the equalizer you can end-up pushing the levels into clipping, but if you run the Amplify or Normalize effect before exporting, the default settings will bring the level down to where it’s safe (if necessary).
If the levels are low, Amplify or Normalize will boost them they won’t boost enough to cause clipping.
…Changing the sound with EQ can “distort” the frequency response but it’s not normally considered to be distortion.
Thanks for the suggestions. I have tried with the Filter Curve EQ and the levels are pushed, but then again the visualizer looks almost the same.
I put the audio on a website that removes background noise and cleans voice, etc. and chose a filter they have that is called Bandwith extension and auto voice eq , and THAT actually changed the levels in the visualizer and it looked more balanced but it made the speakers sound as if they had lisp. The website is called auphonic
This is how they describe part of that filter
Our AutoEQ algorithm automatically analyzes and optimizes the frequency spectrum of voice recordings, removing sibilance (De-Esser) and plosives (De-Plosive) while creating a clear, warm, and pleasant sound
Well, I hope that information helps (you help me).
It’s possible to control the visualization by extreme equalization of the audio you feed it, (even if it sounds unpleasant). Then once the visualization video is generated, replace the unpleasant audio on it with the original undistorted audio.
That’s too much de-essing.
