I am working on a project where I am using the Sonnox DeNoiser built in plugin. It has addressed the background noise issue beautifully.
However, when you render the file it remains unchanged. By this I mean that the resultant file is unaffected by the DeNoiser plugin: the background noise remains.
Tried this a number of times and used all the usual tricks to try and get the render to work. Without success.
In the end, the workaround was to ‘record what is played back’: a real time bounce. This worked.
The DeNoiser was the only plugin loaded, apart from dither. I also tried it without the dither … same result. The plugin was loaded in the master section.
The file was 24 bit 48 kHz stereo wave.
System is current version of WL on Windows 7 Professional.
