Don't want to teach grandmother to suck eggs, but... Cross-talk cancelling is incredibly vulnerable to distortion caused by very early reflections from nearby surfaces- within a millisecond or even 2. (or 1 to 2 feet - sorry, 300 to 600mm) The desk on which your computer sits can be one source of problems - though this is, of course, usually symmetrically placed wrt the speakers. But a an adjacent wall, filling cabinet, extra monitor - all these can throw things out. Generally, if the right side of the field seems to collapse into the speaker, look to your left - and vice versa
Best way to really test it is to carefully put the laptop on a 1m high 'platform', in the middle of a room and stand exactly facing, making sure your head is not within 1m of a wall or similar large reflective surface Dr Peter Lennox School of Technology University of Derby, UK tel: 01332 593155 e: p.len...@derby.ac.uk -----Original Message----- From: sursound-boun...@music.vt.edu [mailto:sursound-boun...@music.vt.edu] On Behalf Of Augustine Leudar Sent: 15 June 2012 14:42 To: Surround Sound discussion group Subject: Re: [Sursound] Can anyone explain this ?
