Could you say that in English. I’m unclear what you are asking.

“True” stereo has different sounds located at different positions in the stereo field (some instruments/voices further to the left, and some further to the right).

Technically a “stereo” track, is simply a track that has two audio channels. If both left and right channels are identical, then the sound is “mono” and will sound identical to a mono track. Audio CDs always have two audio channels, even for mono recordings.

So what exactly are you trying to achieve?
