Tool to fix rapid-fire dropouts?

[aliteralmind]

(I also posted this in Audio Stack Exchange: https://sound.stackexchange.com/ques...-fire-dropouts)

I recorded a phone call and the cell service was pretty shoddy. Here's an example (https://www.dropbox.com/s/wet8oc1o5f...ample.mp3?dl=0). Good briefly, then high-speed dropouts, then good again.

In this image (https://i.stack.imgur.com/nP1y1.jpg), you can see the dropouts to the right of the red line.


Is there anyway to fill in those very thin and frequent dropouts? It seems like it should be reasonably, programmatically, simple to do it. Just fill in those blanks, gradually "morphing" it from the start sound to the end sound.

Any ideas or advice would be appreciated. I've encountered this problem consistently when I record cell-phone calls and would love to be able to deal with it. (I use ZenCastr when possible which provides amazing audio quality.)

(Finally, someone suggested Izotope RX. I'm looking into it, but based on their online documentation and videos, at least (https://www.izotope.com/en/products/rx.html) I'm not seeing this particular problem as being addressed by it. I've written their support and will update with their response.)

Thanks.

I suppose you could do it with some FFT magic & some other stuff, you'd have to detect the gaps ("programmatically" - but only short ones, right?) freeze a bit of audio right before (or after) the gap (with some kind of crossfade) and then crossfade or otherwise splice at the end of the gap. Crikey. Know anyone who's a wizard at Pure Data or Max/MSP ?

Sounds like a product if you can make this happen.

A fantastically laborious way of doing it in Reaper would be to timestretch adjacent fragments of 'good' audio to fill in the gaps. Almost certainly not what you're after.

Cooledit click & pop remover could probably do a respectable job of it. The 'corporate' version is called Adobe Audition.

Edit:
Looking at the waveform, it looks like the gaps are due to noise gating in the cell phone codec (which it uses to gate background noise so it isn't boosted by compression). Doctoring it might be possible, but don't get your hopes up.
