Bonjour, 
l'album Amused To Death de Roger Waters est mixé en Qsound:
... "In the early 1990’s, QSound Labs brought effective, practical three-dimensional (3D) audio technology to music and film production studios in the form of a ¼-tonne digital audio processing station called the QSystem. Meanwhile, video gamers enjoyed ground-breaking QSound 3D audio on Capcom™ arcade machines." ...
..."QSound is essentially a filtering algorithm. It manipulates timing, amplitude and frequency response to produce a binaural image. Systems like QSound rely on the fact that a sound arriving from one side of the listener will reach one ear before the other and that when it reaches the furthest ear, it is lower in amplitude and spectrally altered due to obstruction by the head. However, the ideal algorithm was arrived at empirically, with parameters adjusted according to the outcomes of many listening tests.[2]
3D positional processing like QSound, the multi-channel QSystem professional processor used in the production of pop music and film audio, is distinct from stereo expansion like QSound QXpander or SRS® Sound Retrieval System. Positional 3D audio processing is a producer-side technology. It is applied to individual instruments or sound effects, and is therefore only usable at the mixing phase of music and soundtrack production, or under realtime control of game audio mixing software. Stereo expansion (processing of recorded channels and background ambience) is primarily a playback process that can be arbitrarily applied to stereo content in the end-user environment using analog integrated circuits or digital signal processing (DSP) routines." ...
