Live-Capture Pro change list

Mar 25 2019 v1.26

o The Lake 2 plug-in failed to find the Lake directory causing a hang.

Mar 20 2018 v1.25

o You can now calculate Room-Mode eq when selecting more than on measurement with "operate on" and then right click on the frequency graph and you find "Analyze Room Modes". In the "Room Modes" tab you will get a list with the worst modes for all analyzed measurements, you can select which measurement you see in the toolbar.
o Imported microphone correction files is now normalized at 1kHz when loaded.
o Phase blanking was not executed automatically when doing a measurement...
o The Q-SYS plug-in is updated to export the biquad coefficients in .csv format that can be loaded in to the Q-SYS software.
o + minor fixes.

Jan 30 2018 v1.24

o A couple of measurement presets are now included.
o 6 input channels can be used again if your soundcard support it, see Soundcard settings.
o When importing a microphone calibrations file it could fail if the data was way off, there is now a check that solve this. So if you had this problem import the file again and agree to overwrite the old one.

Jan 23 2018 v1.23

o The microphone calibrator was whining about more than 0.5dB difference even when there was no or less difference.
o If you want you can have your own logo in the graphs, make a uncompressed BMP file with 16 or 256 colors and name it Logo.bmp and place it in the installed folder. The bitmap can have transparency just fill those areas with magenta (RGB=255,0,255). A good size for the bitmap is 64x64 or less, it will be stretched when printing but note the transparency does not work well with all printers and PDF writers so please experiment.

Nov 30 2017 v1.22

o Fixed a fatal bug when running under Windows 10 and trying to change anything in the Transfer Fn Setup dialog.
o The smooth algorithm is improved.
o You can now export the power spectrum in the Capture tab.
o + minor fixes...

Oct 27 2017 v1.21

o Phase-ref in Transfer Fn, right click and see the top of the pop-up menu.
o 3 dB divider on the frequency scale in Transfer Fn.
o + minor fixes...

o Improved compatability with Windows 10.
o Many small bugfixes.

Aug 18 2015 v1.17 (pre-view)

o The user Leq values behaved strange in the SPL/LEQ Meter view.

Jul 20 2015 v1.16 (pre-view)

o New Lake plug-in which now can export eq overlays, see "Lake v2" in the optimizer tab. Since Lake Controller v6.4.0 is the old Lake plug-in not working but it is still bundled for those with old Lake devices.
o Smooth and normalize wasnt working on captured Transfer Fn curves, now it behaves like expected.
o You can now right-click on the windowing selector both in the Transfer Function tab and the Capture tab, there you can add the current windowing if not included. You can also import and export your windowing presets and there is also a properties choice where you can rename and delete presets.
o The logger is now gone and replaced with a sound level meter which show all readings in real-time, it do also show how much that is left (Remaining LEQ) i.e. how many dB more you can put out at the end of the show.
o There is now also a built in web server so you can see the sound levels on your smart phone.
o For those who used the old logger there is a special offer on RT-Capture, just contact Dan.

Jan 12 2015 v1.14

o The windowing choices in the TFn and Capture tab is now replaced with a drop-down box, there are now some basic presets too.
o When using Compute FFT in the Capture tab you can now use the operate on function and change the windowing on those selected as one.
o Rewrote the code that capture curves in the Transfer Function tab, it now looks like the orginal curve.
o Faster wavelets.
o You can now name the input channels in the levelsbar, these are then used for naming measurements and RTA captures.
o + Many more improvements & fixes

Mar 04 2014 v1.12 (pre-view)

o There was an issue with the Lake plug-in, now it works again.

Jan 10 2014 v1.12 (pre-view)

o Background level monitoring now works again.
o You can now name the input channels in the levelsbar, these are then used for naming measurements and RTA captures.
o Fixed the bug where turning off AmbiWin on multiple measurements using Operate On failed.
o Fixed the bug where stimulus calibration would crash the program when running in ASIO mode.
o Dynamic Average is a new feature where an average curve is created for all visible curves in real-time, so if you make a new measurement the curve will be updated instantly. To enable this new feature right-click on the Average button and select the mode "Dynamic Averageing". To start averageing click on the Average button and it will work as long as it is selected, click it again to stop the averageing and the curve is now locked.
o Measurement Presets can now be exported and imported by a right-click on the preset selector in the "Stimulus & Analyser" dialog. This can be useful for transferring the settings between computers, please note that any calibration is not transferred.
o The X-Over Aligner have some improvements, the PIR and Step Response is now normalized as default to make sure you see both bands. The total PIR is now also filtered when the input PIR's are filtered and of course it is also normalized when set.
o Added a setting for the naming of measurements, see bottom of the Settings menu. There you can set the default name of a measurement and if it should copy previous channels measurement name. You can also select if it should add channel number to the name and if you are running in one channel mode; add channel number in that case (default off).
o The SPL logger is now threaded and the memory required is now reduced to 2 days instead of 5, I hope it works better.
o Copy filtered PIR to capture tab in the Output tab was broken, it is now working again as it should.
o The tail correction function in the Capture tab is not stealing the focus anymore, you can now drag the group-delay curve even when tail-correction is enabled.
o The double-click function on the group-delay curve is now improved, a double-click will make sure that group-delay curve is visible by making the right most frequency visible. By holding a Ctrl key down it will center the group-delay scale.
o There is now a listen function in the target tab, and it is real-time so you can drag and listen.
o The listen function in the output tab is now real-time.
o You can now overlay a group-delay curve in the delay aligner (see right click menu).
o The wrapped phase in Transfe Function is now rock stable.
o Added 3 measurement presets that will make it easier to align systems etc, click on the small black down arrow to the right of the green arrow in the toolbar.
o When using Auto mode for the time-window start it is now possible to set the time before the peak called "Pre peak offset", it is found under the Advanced settings in the Stimulus settings dialog.
o Improved the target editor in the Target tab, you can now also drag the high-pass and low-pass filters and there are buttons below the graph to select which one you want to drag. If you right click in the graph you can set the dB scale and also export the target curve as a text file for use in the user weighting in the RTA and the TFn.
o You can now drop frequency response and impulse files on the Transfer Fn tab and they will load.
o Target curves can now be created, loaded and saved in the Target tab. There is now tilt filter, low and high shelf and one PEQ. These can be enabled by clicking the checkboxes and the checkboxes is also used to select one of these. The Load/Save params will save these and the HPF, LPF and the imported curve into one file. ECHO Indigo IO(x) is now working with ASIO so Aubion X8 should now also work (not tested yet), the problem was that the driver wasn't sending the "process now" flag which is documented in the ASIO SDK.
o Mic calibrator is now using a bandpass filter which should make it easier to calibrate the mic in noisy environments.
o WinMLS WMT import was broken.
o Listening on filters in the Output tab is now even more improved.

Apr 04 2013 v1.11

o When averaging the delay now always will be right.

below is a list of improvements since v1.02

o The X-Over Aligner is improved:
1. It keeps the polarity switchen when optimizing, so if it doesn't look good try to reverse the polarity again.
2. You can now see the total impulse response in the lower graph (it turns gray when it is not in sync but it
will appear again in the correct color). Turn it off by a right click on the impulse graph.
3. You can now also resize the SPL vs Impulse graph by dragging the handle between the graphs.

o Improved the Listen function in the Output tab, you can now change between eq'ed or non eq while playing and
it will now also cache a list of last 16 files. The sample rate converter is now also caching converted files
which is found in your document folder in a folder called "WaveCapture Audio Cache".
o The Lake EQ plug-in is now improved and it now works fine with the Lab.gruppen LM44.
o Improved the TWO spinbutton, the focus is now handled better + if you hold down a Ctrl button it will go 100 times faster.
o APEX Intelli-Ware software can now connect to Live-Capture via our Audio Client Measurement API.
o Captured RTA curves can now be saved and loaded in one file with the extension .rta,
to load from the file menu you click on import or you can just drag and drop a file
on the RTA and it will load.
o Now with our Measurement Audio Client system, where you can do RTA and Transfer Function measurements via
the network in your own software via a DLL. You can request a developer kit on our web (see Live-Capture Pro).
o Improved the accellerated chirp, it now has better SNR.
Please note that you should re-calibrate your stimulus presets.
o The target tab now have 2 vertial cursors which is used to find the target level automatically.
o The horisontal reference leveloffset cursor should now never dissapear...
o Added high-pass filter option for chirp, this may reduce low frequency problems when using high start frequencies.
o User weighting is now available in the RTA and in the Transfer Function tabs.
o Weighting can now be used in the RTA when connected to Lake Controller.
o Improved error handling when last used soundcard is not found.
o The serial number protected version now works in Wine v1.2x on Intel Mac.
o A "High Preformance" mode will half the buffer size, for users with quad core and higher.
o Current preset is deselected when changes are done in the Stimulus & Analyser dialog and the user is not updating the current preset and press OK.
o When averaging curves the resulting curve now always get a 1s time window (the same length as the impulse).
o Operate On now works with the windowing functions MultiWin, the overall logic for Operate On is also improved.

Jun 16 2009 v1.02

o Added measurement presets in the Capture tab, you can have 16 presets and they are configured in the Stimulus setup dialog.
o The soundcard calibrator will now calibrate the current and the presets when you select to calibrate all stimulus types.
o and more...

Previous updates

o Lake interface is included.
o Improved X-Over Aligner, you can drag almost anything and you can zoom in both graphs. The automatic finder algorithms is also improved (Flattest Amplitude and Using X-Over Freq.).
