Cubase Pro 11, make Spectralayers Edit on audio track perminant so can remove Spectralayers?

Windows 10
Cubase Pro 11
Spectralayers Pro 10

Is there a way to save any editing made using Spectralayers Pro 10 as an extention back to an audio track (wav file) and then be able to remove the extention to save on ASIO or CPU usage?

I am unable to find the answer to this within the online hel[ as it seems to refer to Cubase 12 and/or 13 only.

Within the online help, to make and edit Permanent it says…


  • Do one of the following:
    • Select the audio event, and select Audio > Extensions > Make Extension Permanent.
    • Right-click the audio event, and select Extensions > Make Extension Permanent.


All editing that you performed with the extension in the Editor is permanently applied to the audio event. The Extension field on the info line is set to No Extension.

In Cubase 11 if I go to Audio > Extensions there is no “Make Extension Permanent” option.

In Cubase 11 “right clicking” on an audio track only shows the cusor object selection menu.



Use the Bounce Selection or Render in Place function, please.

Hi Martin

Thank you for your suggestion which I have just tried.

It has bounced the the part I was editing and allowed me to remove the original audio file that had the Spectralayers Pro extension.

This has caused a new problem.

The files that I am working on are parts of a vocal comp (so it is made up of various voical takes). I was removing a mouth click with Spectralayers from one of the comp parts and all of the parts are placed on one single track using X fades (which works great) and means yoiu do not have bits of vocal on multiple tracks.

The new bounced file will not allow me to add it on to the track with the rest of the parts, Where there is silence at the end of the new file cubase mutes the following clip until the silence ends and then brings the next part, it is no longer a smooth transition.

Normally, if you put two audio files on the same track and lay one over the other, where there is silence in one, you will still hear the one without silence?


Would the Render in Place fit to your use case then?
