    Dear all,

    If I (being mad and in need of certification) wanted to find out what the peaks and dips of my room were so I could optimise my system to get the flattest response possible, how would I achieve this without spending an absolute fortune?

    Regards,
    Brad

    A decent SPL meter and some slow sweeps can help.
    A test CD with bursts and TONE sweeps/STEPS from 20hz-20khz is useful.
    Run the sweeps slowly and measure the in room response.
    There is not much more that you can do without spending quite a bit of £$'s!

    This will identify room modes etc that you can control to some extent with drapes and curtains/ speaker positioning etc.

    I've found these 2 channel sweeps to be flawed for movie setups, I get a far more accurate reading of my room's behaviour with a Dolby Digital sweep found on the calibration disc AVIA. Just my opinion of course........

    To get even more accurate readings from the standard SPL you can get a mic add-on that plugs into the SPL and this in turn is fed into the PC via a Midi connection, touch of overkill springs to mind though.
