How to remove "fry" - vocal raspiness?

Hello, I’ve gone round in circles trying to remove a kind of rumbly, raspy sound in a voiceover track. It’s the main reason why I purchased SpectraLayers.

It seems to occur intermittently and although I’ve tried to select various areas in the audio, I can’t identify where it’s coming from (because once I do then at least I could remove or ameliorate it).

Also, I don’t know how much overlaps with the actual “voice” sound - I don’t want to remove or affect the voice itself - just remove the “rumble” that may be coming from somewhere in the throat or perhaps a vibration of the bones in the mouth or something!

Any idea where to start?

Listen especially to the words: throughouttimeswhen I was metdoubtI faced four (decades ago).

Try this awesome thread!

haha, I started that thread here a good two years ago. I haven’t found a good solution yet. The main problem is identifying which part of the audio signal is the crackly or raspy bits.

That’s why I thought it better to start a new thread. Once you can accurately identify the “noise” elements, then one can run Spectral Denoise on Izotope RX Advanced or Find Similar on Spectralayers.

What I like about Spectralayers so far is that you can select parts of the signal with the paintbrush tool. But for the life of me, I can’t find the noise (or at least separate it out from the voice signal).

Maybe there’s a different way to visualize the audio. That would probably nail it!

Try this (a bit tedious selecting process though…):

  1. Concentrate on the frequencies where the raspiness is the most pronounced, that is up to 2,2 k. Select this range with the Frequency Range Selection tool.
  2. Copy to new layer.
  3. On this new layer: use the Harmonics Selection tool to select the spoken words (this could be tedious…); use Thickness 2 pixels, Master Rank 1 and Count 35. Select with the mouse pointer on the lowest “spoken words bands”.
  4. Erase the selected areas (Backspace multiple times). The resulting material will be the warbles/rasp.
  5. Phase invert this Layer and play it together with the original layer; Merge the layers when satisfied. The result should be significantly less raspy.

Much better!

Seems like the tools aren’t good enough for complete transparency yet … sound processed to me.

I should add I’ve used a simple LPF, e.g., down to as low a 5-7K in a male singer, to get rid of a singer’s vocal fry. I guess it would depend on the musical setting, but in the right circumstances it can sound quite transparent.

Nasel passages are causing the added noise, IMO. I can’t imagine how something so ingrained in the delivery could be separated from the final product.
