Current Firmware: 7 June 2010
New features and changes in firmware of 7 June 2010.
The following are the most significant changes. Not all refinements are listed.
1. The ALL speaker measurement procedure now allows measurements of a speaker or speakers to be
made separately in stages. This provides a completely flexible way to create multiple virtual speakers
in different locations and with different channel assignments from lesser numbers of real speakers. As
a result, a channel on/off screen appears at the end of every measurement sequence to specify which
channels are to be saved. For the typical ALL procedure, the channels will be set the same as when the
measurement sequence began, in which case one additional OK keystroke is required.
2. Direct mixing of bass (LFE and/or redirected bass) into the headphones is now possible. This is for
situations where there is no real subwoofer to be measured, or where there is only an inferior
subwoofer, or where the room has modes that make low frequency performance problematic.
3. The ONE, LsRs and LbRb speaker measurement procedures now allow subwoofer (or other)
measurements to be added, so 5.1 and 7.1 are now possible in addition to 5.0 and 7.0, etc.
4. The ONE, LsRs and LbRb speaker measurement procedures now use the default channel
assignments.
5. Virtual loudspeaker arrays assigned to the same channel can now be created from a single real
speaker by using an option in the AVG LOOK C menu which allows multiple sweeps to run with
pauses between sweeps. During the pauses, a speaker can be moved to different locations. The typical
application is to generate multiple virtual subwoofers from a single real subwoofer.
6. Measurement processing has been refined to improve the capture of multiple speaker arrays.
7. The TE screen is no longer momentary; it remains until CANCEL is pressed.
8. Manual EQ now uses thirty-one uniform 500 Hz filter bands (except for the last band).
9. A CONTROL MENU has been added, allowing enable/disable of
UART and USB wired remote controllers in addition to the IR remote.
10. The TE menu has been modified to accommodate wired head trackers.
11. For look angle adjustment of “looking centre” after measurement, the left and right speakers’
phantom centre image is now used instead of the centre speaker. Thus stereo and other PRIRs which
contain no virtual centre speaker can be adjusted; and perceptual sensitivity is increased.
12. The HPEQ inverse EQ compression factor (XFACT) bands are now 0-5 kHz, 5-10 kHz, and
10-24 kHz.
13. The head tracker SCOPE default is now HOLD.
14. Channel assignment options now appear in SMPTE/default order, and the C, LsRs and LbRb
measurement procedures use SMPTE/default channel assignments.
