o + some more improvements.

Sep 07 2007

o Added an option to calculate minimum-phase when importing a curve from other programs.
o The microphone selector now has an import utility where you can have it to calculate the minimum-phase etc.
o There is now also a FLAT microphone selection which make it more clear that a microphone is used and the sensitivity can be changed freely for the FLAT microphone.
o Added import support for two more frequency curve files.

Aug 18 2007

o Added a new feature called MultiWin in the capture tab, this is an improved form of the DuoWin with even better removal of the reflections (in this case at low frequencies).
o You can zoom the frequency graph in the capture tab with the mouse, hold left button down and drag down to the right and it will zoom in and by dragging up to the left it will zoom out.
o Added Cepstrum.
o Improved measurement toolbar where it is possible to select to show Phase and/or Group-Delay, Magnitude Scale and also PIR, ETC and CEPSTRUM.
o The stimulus can be calibrated in the soundcard settings, there is an option to calibrate all stimuluses or just the current.
o + some bugfixes and improvements...

Apr 30 2007

o There is now a measurement properties dialog, just right click in on a graph in the Capture tab and select Properties.
o The dB scale top in the Capture tab can be changed by dragging the mouse over the scale but first do you have to turn off"Automatic Scale Top" by deselecting it via the right click menu in the SPL graph.
o The size ratio between the SPL and PIR graph can be changed by dragging the = between these to the right.
o When using multiple PIR it is now possible to select if it should scale the graph to the largest PIR, see the right click menu.
o + more...

o Bugfix: When double clicking on an EQC file would EQ-Capture crash.
o UI Fix: When clicking on the measurement bar resizer will it refresh even if not dragged.

Apr 03 2007

o Just a cosmetic fix, it now fits in a resolution of 1024x768 pixels.

Mar 07 2007

o Help has an updated Capture tab section.
o The normalisation frequency for the difference and normalisation is now set by dragging the red vertical cursor when one or more operate is checked.
o Added a difference feature which is enabled when only two curves are selected via the operate on check boxes and if one of them is active is the result diff = active - other, or if none is active is it the diff = first - next. The difference curve is drawn with a dashed line and it can also be exported to a text frequency curve (right click on the frequency curve and you find it in the bottom of the menu).
o Zooming of the PIR has been improved, you can now scroll left and right with 3 new buttons |< =home, < =left and > =right.
o + some minor fixes.

Feb 22 2007

o PZO is implemented according to Zoelzer anno 1993, this is the type of PEQ that is used in the XTA x-overs.
o + many bug fixes and improvements.

Dec 21 2006

o 2 minor bugs were fixed, normalisation of non-SPL curves and export of filter curve.

Dec 20 2006

o First retail version...

Known Issues

o There are redraw problems with the curve selector in the capture tab, this is not a problem on NVidia graphic cards but on others like Intel. As a temporary solution do you click on the sizer just above it to the right (the 4 shadowed lines).
o Print preview may crash the program sometimes so it is recommended to save all the work before looking at a preview.
