iZotope RX 11 – Remove detuned chorus effect – Hosts & Applications (Sequencers, DAWs, Audio Editors, etc.) Forum

That is a very short audio clip. It would be interesting to hear the original.

What I hear is a recording of acoustic guitar, but chopped up and stitched together again where short pieces have overlap of two sections.

I’d say you used the wrong tool, or your recording is not suitable for it with those settings, or what you try to do with it.

Timing errors are imho best corrected by splitting it up by hand (at convenient points) and shift the pieces where you stretch individual pieces if they need to be longer and just cut off the end if they are too long. Once the timing is straight you can use a simple stretch to adjust tempo, if needed.
