Title: Suggestions for cleaning up crackles/pops on recording
Post by: themonkey on January 13, 2012, 02:37:44 PM

I recorded a nice set the other night and in the process of making a matrix.  Anyhow, on the board tape there is plenty of cracks/pops on the vocals.  Not sure of the cause, but looking for suggestions to clean it up.  I played around with Audicity's low pass filter and got some improvement, but not much.  I also have an older version of Wavelab (4.0) running on my old computer I could work with.

iZotope RX2

Best results scrubbing each pop separately.

It's magic.

Izotope works great.   The pop and crackle filters in Samplitude work well and just take a bit of playing with the settings to eliminate what you don't want without doing harm to what you do- not sure if there is something similar built into Wavelab.  You may try one of many available inexpensive or free VST plugins primarioly targeted at cleaning up pops and crackles on digitized analog records.

just be careful. it's an audio stake knife; very powerful, but very dangerious if you aren't careful.

The Samp filters and VST plugins I mentioned are not spectral editors, but instead look for unusual sharp transients characteristic of pops and crackles (I think).  They are more of a 'check to make sure you have it set appropriately, then apply to the entire track' sort of thing.  That might be more practical if you have lots of pop and crackles to deal with than a spectral editor that has more capability for dealing with all sorts of things, but requires editing each event seperately.

Thanks.  Izotope RX2 looks good, beyound my budget for the time though.  Not sure what the current version of Wavelab 7.0 would have to offer in this realm, but might consider it in the future.

I'll search around and see what's available for free VST plugins.  Luckily, my audio turned out great for the time being.

In WaveLab 4/5/6 there is a pencil tool where you can redraw the audiowave ;) Works GREAT for balloon pops and clapping at shows. A Little labor intensive, but well worth it in the end. I just did this for balloon pops from saturday night, and you can BARELY hear them ;)

Cool, I'll keep that in mind.  I looked into the newest version of Samplitude Pro X, which looks like a really nice and well rounded DAW.  I downloded their 30 day free trial for Pro X and have played around with their restoration filters.  The dehissor appears to be my ticket at the moment.
