Assuming I get out in time, later/later (or maybe even tomorrow) I will
record a track from an 'enhancer disk' which sweeps from 20 to 20,480 Hz
at
the rate of + one octave every 12 seconds.

Oh you really aren't going to like the look of what that shows. Rooms
are just horrible.


OK, this is the CD track I intend to use - let me know if there's anything
unsuitable about it?

Also, can you confirm the start frequency - I have no trouble hearing it
from the very start, even on the computer setup with 2.5 inch drivers...??

Right, orf aht for a while now....




It starts out at 20Hz OK, but it really is unsuitable for the job. It
will spark off every standing wave in the room, and you really will be
shocked at how lumpy it is. Take up Nick's offer - it will be miles
better.

That sort of sweep is really only for internal testing of equipment,
not for rooms.


OK, forget that then. It looks like I'm going to have get summat sorted out
on the mic front.
