#Levelator increases background noise code#

Also, normalizing (on Audition) doesn't work on the average, it works on the peak(s). (Technical note: most compressors I've seen work in both directions. Or maybe do step #2, and then run it through this one. That should have the settings built in to make the final product good enough. Leveler is a simple, combined compressor and limiter effect for reducing the dynamic range of audio. That *should* get the waveform looking pretty flat, and then you normalize it to -1db.ģ- Or, look for a compressor plugin that is something like 'FM Radio' or 'broadcast post-processor' or something like that. So you set your compressor to (for example) reduce anything that's above -12db by 12db.

If you look at the waveform, you might see that the other person's voice never goes above -16db. I'm not sure about audacity, but in Cool Edit (or Audition), you can program the compressor with rules. Then you clean it up in post.)Ģ- Once you've got a clean recording, set up a (dynamic?) compression filter. Any surprises still have some headroom to work with. (The way around this is to record at a fairly deep bit depth, and shoot for say -6db as your zero point. But in digital, it simply cuts off and you lose information. In the analog world, you can overdrive the input a little and it usually will sound OK. Digital recording is all about NEVER clipping. Even if you reduce the volume, the clips will just be quieter, and still 'sound' loud.

And then subtract this dominant color from the images who has clusters in it: def substract (image, dominant): cells cv2.imread (image) cells cells :, :, 2 cells cv2.subtract (cells, dominant) This code is not working though. Are the peaks of your voice clipped? If that's the case, you need to reduce the volume you are recording at, because you really can't clean those up once they are clipped. The dominant color should be the background noise. This would be optimal.ġ- Look at the waveform. (I would note that this is going to sound like ass no matter what you do, especially if the room you are in is echoey.) There should be adapters available that you can plug in between the handset and the base of a desk phone, or between a cell and a headset. If it is just a digital recorder next to a speaker phone, stick the recorder right next to the speaker. My first suggestion would be to find a different way to record the audio.
