AB  - The subjective effects of controlled multichannel audio bandwidth limitation and effects of selected down-mix algorithms were compared. The investigation was focused on the standard 5.1 multichannel audio set-up (Rec. ITU-R BS.775-1) and limited to the optimum listening position. The obtained results of the formal listening test show that in general listeners prefer limitation of number of channels to limitation of bandwidth, for a given 'information rate'. However, for some programme material containing foreground content (direct sound) in the rear channels, limitation of either parameter has a similar effect.
