4. Automatic backup of all files to SD card.
5. Linear taper can be applied to PRIR with user-definable start and end points.
6. Microphone calibration and test procedure.
7. Optional password protection.
8. Headphone limiter threshold and release controls.
9. For optional meter bridge, phase meter adaptation rate control.
Changes:
1. For presets, PRIR and HPEQ files are automatically saved to non-volatile memory when loaded,
and preset erasures are also non-volatile. Parameters remain volatile until a preset is saved.
2. The toggle (on/off with same button) functions of the
MIX
and
PASS
keys have been dropped to
prevent inadvertent re-switching by holding the key too long. The
SVS
key cancels
MIX
or
PASS
, as
before.
3. In the
ALL
mode, a virtual centre speaker is generated automatically not only when only
L
and
R
speakers are selected for measurement, but also when any number of speakers is selected (omitting
C
).
4. When head tracking is disabled (
TD
), the head angle is set to the PRIR look-centre angle.
5. The channel 7 and 8 outputs are driven when the tactile output is disabled.
6. Rev. 2.0 file format (PRIR20XX.SVS, HPEQ20XX.SVS), enabling future enhancements.
7. For the
ONE
mode, speaker delays all conform to the delay measured during the first sweep.
8. For the
LsRs
and
LbRb
modes, the fixed speaker delays are reduced to 8 ms (384 samples).
Fix:
Hardware ID menu fixes occasional display line transposition and power up/down thumps in early
Realisers.
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.
