Can you remove a glitch after recording?

Nigel:

Help me understand what type of 'glitch' you are referring to.  Do you mean a series of clipped peaks or a gap in your audio?  I agree that you shouldn't spend too much money on some things - other things are worth the investment.

My suggestions include:

#1 Retrack that vocal - unless the client is unavailable or project costs risk over runs
#2 Does the section repeat (e.g. chorus) where you can copy and paste a usable section over the problematic area?
#3 I use Izotope RX2 for both of the situtations I mentioned above.  It does a miraculous job on audio gaps and an excellent job on clipped peaks.

RX Declipped Example

I couldn't find the demonstration video on audio gaps but it is fairly impressive given the ease of use.

dillyboy, how about posting a screenshot of the glitch, zoomed in fairly tight? Whether it's digital overs, dropouts or overflow inversion, the ability to transparently repair a glitch depends mostly on how wide it is. In most cases, there is lost data that must be reconstructed, and that can be very challenging - it's a matter of putting data back in that is no longer there. The shorter the duration of the anomaly, the easier it is to fake the missing data.
