Listening through headphones and at the same time through speakers sounds very big, great

This was tried by chance on Uher. The RadioShack mixer had been connected to line out.


Signal path:


                                       - Uher monitor speaker
Uher 4200 reproducing -
                                        - Realistic disco mixer - Sennheiser HD 580 headphones


The reason it sounds so nice could be:


The direct sound at speed of light from headphones and the speaker sound at speed of sound in air therefore time delay from speaker to ears effectively create what a revebaration chamber does.


A similar effect happens when recording with a mic and at the same time a loudspeaker plays in the room (from the output of the recorder) what is being recorded. It is effectively an echo or reverberation chamber with feedback.


Adjusting mic from speaker distance adjusts time delay.


It sounds like (is) artificial double tracking.
