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.
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.
