I recorded a song that has very open stereo, I didn't put the bass in mono and I had problems as you will notice in the audio, there were some jumps and landurfing.

Re: Ever so slightly successful stereo embossing

Re: Cutting with a diamond cnc engraving bit?

making a cone for a good cutterhead is not an easy task, after many attempts and finally you can make one and soon realize that you need 2.
