Description:
Using either Audio Quantize or manually editing via AudioWarp produces clicks, crackles, and glitches that did not occur in previous Cubase versions.
Steps to Reproduce:
- Create an empty project in Cubase 9. (I work at 32bit/48kHz).
Add an audio track.
Record some audio. (Recording guitar or bass with simple eight notes at a low level works best; the clicks stand out better).
Select the audio and Quantize it (hit the Q key). elastique - Pro Time was used.
Play it back. clicks, pops, and glitches are present at many of the calculated hit points.
Example Files:
I’ve included two files, both exported at project sample rate of 48kHz:
-
1NonClicky: The raw audio recorded through Cubase. No clicks. This is recorded at a very low level (-32dB-ish) to help highlight the clicks after quantization.

2Clicky: This is the audio after applying quantization. Clicks and glitches are present, even in the rendered file. They are most noticeable after Bar 7 (if imported into a 120bpm project).

I’ve also been able to reproduce by importing 1NonClicky into a blank project and applying Quantization there. Results become more pronounced if applying multiple rounds of Quantization. None of this occurs when importing into Cubase 8.5.
