This stereo panner assumes that the signals

independent), or that they contain a stereo image which is
mono-compatible, such as a co-incident microphone recording, or a
sound stage that has been created with pan pots.*

With the default values it is not possible to alter the position,

The stereo panner will introduce unwanted side effects on

When you reduce the with, you are effectively summing two highly

Depending on your material and on how much you need to manipulate the width,
some degree of comb filtering may be acceptable. Then again, it may not. Listen
