RoomEqWizard : uscita nuova versione !

[WillyWonka]

Il buon John Mulcahy ha sfornato una nuova versione dell'ottimo RoomEqWizard.

Queste le novita' :

• Room EQ Wizard Revision History
  
  V3.23 28th Oct 2005
  
  Warnings about overwriting filter settings and measured data
  only given if there are settings or data to be overwritten
  
  Use antialiased rendering on zoom cursor and zoom box (if selected in Graph menu)
  
  Revamped the graph traces display to provide multiple groups of traces chosen via a drop-down box in the graph panel
  
  Line colour/style for traces is shown next to trace name
  
  Removed "lin"/"log" indicator at RHS of graph Y axis, now shows "Hz" or "s" instead
  
  Added units indicator at top of Y axis
  
  Added display of impulse responses, normalised to the peak value
  
  Added display of the window used when calculating frequency response
  
  Only use CZT for 0.1Hz response resolution when end Freq 1kHz or less, above that use conventional FFT for 0.183Hz resolution
  
  Cut size of all channels 10Hz to 20kHz sweeps mdat file from 37M to 10M
  
  Reduced RAM usage, peak now 76M when all 9 channels have been used for 10Hz to 20kHz sweep measurements
  
  Added export of Impulse Response data as text
  
  Added support for FBQ2496 with Midi setup, only 12 (of 20 possible) filters per channel in this release
  
  Added progress monitors during Midi downloads
  
  No longer capture and process the left channel for sweep measurements, all calcs are relative to the stimulus
  
  Added support for soundcard cal file with menu entries to measure response, load and reset the cal data and save a measurement as cal data
  
  Cal file responses are drawn across centre of graph regardless of graph Y axis position
  
  Traces for mic/meter and soundcard cal are only enabled (and so can only be selected) when a file has been loaded
  
  Removed the loopback indicator and the menu entry to enable loopback
  
  Removed the SPL Limiter check box and associated functionality
  
  BFD Pro (DSP1124P or FBQ2496) can have filters from any channel downloaded (previously was only sub or sub2), with choice of whether to send the filters to the left or right bank
  
  Setting measurement level has been revised, should be much easier to handle now
  
  Setting input volume control and calibrating the SPL meter reading have been separated, can cal the reading independently after setting the input volume
  
  Making measurements (and setting target level) are allowed even if the input level has not been set, SPL cal has not been done or measurement level has not been set - get a once-per-session warning message
  
  Connections message for target level only shown once per session
  
  Dutch help files removed (too far out of date)
  
  BUG FIX: loading a set of measured data would give null pointer exception if there was no measured data for the current channel
  
  BUG FIX: Exporting measured data as text would report "No measured data" from sweep measurements
  
  BUG FIX: Corrected numerical ill-conditioning in biquad magnitude calc for very high Q and low Fc
  
  BUG FIX: Set Target Level could set a level outside the allowed range of the target level spinner
  
  BUG FIX: Setting Target Level chooses sub or speaker cal depending on speaker type selected for the channel, prev only used sub cal on the Sub channel
  
  BUG FIX: Setting measurement level chooses sub or speaker cal depending on speaker type selected for the channel, prev only used speaker cal

Come vedete ora supporta via MIDI anche il FBQ2496 (quindi forse anche il DEQ2496...)

E tutto questo e' gratis....

Thanks John !

Grazie anche a te.

Ho ritenuto opportuno spostare la discussione in questa sezione in quanto più pertinente (installazione - setup), dandole quindi maggiore visibilità; la sezione in cui avevi postato si riferisce esclusivamente al materiale da riprodurre: musica, film.

Ciao

[pela73]

ho scaricato il programmino ma visto il mio vasto sapere riguardo la lingua inglese non ho ancora capito una mazza di come si usa.
non c'è qualche anima pia che ha già provato ad usarlo che può spiegare come procedere.
un saluto a tutti
ciao

Ma come ti capisco Mirko
Dall'alto della mia ignorantaggine, mi sembra più in interfaccia con funzione di misurazione per i 3 equalizzatori supportati.
In pratica dovrebbe essere: misurazione, elaborazione, "coordinate" da dare all'eq (magari tramite porta midi o com aggiusta direttamente lui l'eq).
Ma potrei anche essere fuori strada di brutto brutto brutto.

[pela73]

ma porcaccia la miseria non era meglio l'avatar del milan con il tuo nome,quella nuova mi attira lo sguardo,continuo a guardare a sinistra.
mannaggia mannaggia.
tornando in discorso stiamo a vedere se qualcuno ne sa più di noi,
perchè a vedere così sembrerebbe un programmino interessante.

John Mulcahy e' andato avanti ed e' arrivato alla versione 3.27

L'aggiunta piu' importante e' il plot Waterfall



Dalla 3.23 ecco cosa e' cambiato

V3.27 22nd Dec 2005

Impulse responses shown as absolute dBFS and %FS values rather than normalised to the impulse peak value. Y axis settings on the IR controls page are updated after each measurement to suit typical impulse magnitudes for the measurement range
Baseline for dB plots moved to -180dB
Now render to intermediate images to get rid of the sluggish cursor movement when viewing complex plots like waterfall and impulse responses
Default for waterfall antialias changed to on
Added z slider to waterfall controls to adjust perspective effect
Added button, menu entry and shortcut (ctrl+shift+J) to save the graph image as a jpeg
Aux channel now always labelled "Aux" (was "Sub2" for equalisers other than TMREQ)
Added Measurement Averaging graph group allowing averaging of frequency and impulse responses
BUG FIX: Final slice of waterfall could have old data in it after regenerating the plot
BUG FIX: Waterfall numeric display was always from left channel
BUG FIX: Warning message that "Impulse peak is not where it should be" could appear when it should not


V3.26 18th Dec 2005

New features

All 20 filters of an FBQ2496 can be set up
Added a Low Frequency (10Hz to 750Hz at 48k sample rate) Spectral Decay plot, providing a 2D view with the t=0 response plus 8 slices at configurable spacing with configurable slice window width
Added a Low Frequency Waterfall plot (also 10Hz to 750Hz) providing a 3D view over a configurable time period with configurable window width for each slice. Note that for comparable results to ETF 5 waterfalls, use a window width that is 1.4 times the ETF gate time.
Added an Oscilloscope-style plot to show the generated sweep and the captured data as time-based plots (static view of captured signals, not live data)
Added fractional octave smoothing for frequency response traces
ETF *.pcm impulse responses (exportable from Full Range measurements) can now be imported (allows the Low Frequency Spectral Decay plots and Waterfall plots to be generated from the data)
Each channel's impulse response and the impulse response of the channel's filters can be exported as 16-bit mono WAV files
Added a new Generic equaliser type, mainly for use in generating filter impulse responses for export. Offers parametric, low pass, high pass, low shelf, high shelf and notch filters with centre frequencies from 10Hz to 22kHz in 0.1Hz steps.
Cursor position now shown at bottom right corner of graph when cursor within the graph area
Impulse response windows can now be offset from the impulse peak using the Window Ref Time control in the impulse response controls graph group. The position of the window ref is shown by a vertical dashed red line, the window extents are shown by vertical dashed black lines. If the ref or the extents are changed, the new window extent is shown by a highlighted region on the graph until the new values are applied to the response
Soundcard tab added to filter panel, shows measurement results for soundcard including -3dB points, flatness and 1kHz distortion figures
Added a View menu entry to show the filenames of the mic/meter and soundcard calibration files, if loaded
Check box added to each multi-channel graph group to offset the traces from one another
Dragging the mouse with the right button pressed shows deltaX and deltaY measurement cursors as well as drawing a zoom box. To zoom to the dragged area, click within the box when text underneath indicates this is allowed, any other action dismisses the box.
Added a "Delete channel data" option to the analysis menu, deletes all measured data for the current channel
Added a button to set the graph axis extents to manually entered values
Added a "trace offset" spinner for each channel that shifts the trace vertical position in steps of 0.1dB. The data values are not affected, only the position on the graph. To apply the offset to the data values, use the "Add to Data" button. Note that data generated from a sweep will revert to its original level if the "Apply Windows" button on the Impulse Controls is used as this recalculates the frequency response.
Lowest frequency of measured data derived from sweeps is set according to width of windowed impulse to exclude invalid data for frequencies whose period is less than the window width
Measured and Corrected traces for data which has had inverse C weighting applied show a "C" icon next to the value on the graph traces
The frequency resolution corresponding to the current impulse response window width (Pre ref plus post ref) is shown on the Impulse Response Controls graph page
Useability Enhancements
Selection of graph groups has been added to the view menu with associated Alt+1/2/3/… shortcut keys
Reformatted SPL Meter and Signal Generator to better match single channel operation, selection of input channel provided via radio buttons on the SPL meter, Signal generator signals are on both L and R output channels, VU Meters changed to a mono version
Control for post-impulse window duration and Apply Windows button are accessible on the Filter Adjustment page as well as the Impulse Response Controls page
Expanded text in warning messages for soundcard cal and target level setting
Further revisions to the input/output calibration procedure and accompanying help text, changed measurement level setting to simplify it and remove dependence on input cal (now done before input volume setting), changed input vol setting procedure to use the Wizard's signal generator as the cal signal source
Improved action of axis scroll bar sliders, especially at high zoom levels. Arrow buttons move 1% of span, clicking in track moves half of span (min 5Hz, 500us).
Graph axis settings (range & position) for each trace group are now independent of one another, and for the impulse response groups there are two independent sets of settings, one for the dB axis and the other for %
Added 0.1 and 0.2 as Y axis grid steps and allowed higher zoom levels
Other Improvements and Changes
Longer settling time for measurements of Target Level
Modified the measurement sweep to extend down to DC to improve accuracy and remove windowing artefacts from impulse responses. Upper end of sweep can go to half the sampling rate.
Default shape for pre-impulse window changed from Rectangular to Hann
Default impulse window limits changed to 500ms post, 10ms pre (but pre impulse time increased when end frequency of sweep is below 1000Hz
Corrected name of Hann window
Default Y axis for impulse response plots changed to dBFS
Dialogs centred on graph area
When tracking is active rms numeric and bar displays on SPL panel show the DFT reading
Soundcard measurement can be selected/viewed like other measurements
Moved selection of peak data table display from graph menu to view menu
Harmonic distortion displays are disabled when harmonics of the frequency being tracked exceed half the audio sampling rate
Graph upper limit changed to 30kHz
Signal generator upper limit changed from 20k to half soundcard sample rate
Limit find peaks upper frequency to 500Hz (detection unreliable at higher frequencies and 500 is already beyond the range of modal resonances correctible by EQ)
Warn if peak input level of a measurement is low
Warn if soundcard cal file sample rate does not match current sample rate
Catch a NullPointerException during init that can occur if the Windows theme is not supported by the JRE
Tweaked the trace colors
Menu entries for reading/downloading filer settings moved from "Unit" menu to "Equaliser" menu, Unit menu deleted
Plotting of measured and corrected data and filter responses revised to ensure extrema always shown regardless of freq axis scale
The Wizard only adjusts axis settings on the Filter Adjustment page to frame new measurements, and then only if the current range does not encompass the new measurements. It will not alter the axis settings on any other graph pages.
No longer force linear freq axis for measurements ending at 200Hz or below
Start Frequency spinner is disabled for sweep measurements (not used, sweeps start at DC)

Bug fixes

Some files using comma as decimal delimiter were wrongly imported (cal files and data files)
Graphing of measured traces was broken during manual and stepped sine automatic measurement
Input vol setting could give incorrect result and leave vol at max or min
X axis Zoom out button did not work when slider was on right edge
Spl axis top/bottom levels sometimes not set correctly to encompass measurement
Bottom horizontal grid line was sometimes not labelled
Track Cursor would try and update generator frequency when X axis was not frequency
Graph trace tooltips were not being displayed
Manual Measurement and Auto Measurement buttons were not disabled during auto measurements
Apply Windows button in Impulse Controls group was sometimes not enabled when it should have been

V3.25 30th Oct 2005
BUG FIX: Fixed obfuscation problem that stopped measurement data sets saved with 3.23 or 3.24 being loaded again
BUG FIX: Find peaks would not locate any peaks when run on loaded measured data sets


V3.24 30th Oct 2005
BUG FIX: Fixed broken links in help files
BUG FIX: Set Target Level did not run unless cal had not been done on input or output

ed e' sempre GRATIS....

Thanks John !

uscita versione 3.28

V3.28 16th Jan 2006

Added File menu entries to load and reset a "House Curve" to define the desired target response shape - typically used to define a boost for the lower part of the subwoofer range
Added a field to show the bandwidth in Hz of parametric filters
Added renaming of channels by right clicking the tabs in the filters pane, names remembered for next startup
Speaker type and cutoff settings in the filters panel are remembered for the next startup
Settings used in the Set Extents dialog are remembered for the next startup
Added Ctrl+3 as a shortcut for applying one-third octave smoothing to current channel, with corresponding entry in the Analysis menu
Added 1/2 octave as a smoothing step in the Trace Smoothing selections
Made the fractional octave smoothing much faster
C-1 icon now shown by spectral decay and waterfall plot trace values if generated data has C weighting compensation applied
Measurement info now states ETF5 PCM Impulse Response if IR was imported from a pcm file
Changed default freq axis setting for the Filter Adjustment group to logarithmic
Cal files and imported data files can now have any extension, though default is to show files with extension .cal in the cal file dialog and .txt in the import data dialog
Added preview to the .pcm file chooser
Added a cancel option to the 'load mdat file' confirmation dialog
Paths to mic/meter and soundcard cal files are remembered after cal data has been cleared
Added a help entry listing all the keyboard shortcuts

Removed serial port selection menu for non-Windows systems
Don't force graph axis min extents on new sweep measurements

Bug Fixes

Wizard would not close if an audio input device had never been selected
Stepped sine measurements did not work
ctrl+shift+S was assigned to saving measured data set and sending channel filters to unit, sending filters to unit changed to ctrl+shift+F
Measurement info in data summary was changed when Apply Windows was used
Spectral decay and waterfall plots were cleared when Apply Windows was used
Trace smoothing factor was common to all traces, should be independent
Cursor line on back wall of waterfall was sometimes slightly offset from correct position
Pressing Cancel on the Set Target Level progress dialog did not cancel the procedure

Per questa roba Edofede e' il riferimento assoluto.
Adesso gli linko il 3ad e vediamo se ci da una mano ufficiale.

Edo siamo nelle tue mani

[WillyWonka]

c'è il supporto per il FBQ2496, non c'entra nulla ?
potete provare ? Puo' darsi che i comandi midi siano gli stessi...

All 20 filters of an FBQ2496 can be set up

L'FBQ2496 e' la nuova versione del DSP1124.

Il DEQ e' molto piu' duttile e completo, non c'e' paragone, infatti ai 20 filtri parametrici del prodotto citato ne aggiunge 62 grafici, l'unita' di delay, l'eq. dinamico, l'RTA, gli indicatori di livello, l'I/O analogico-digitale etc etc

l'instancabile John ha sfornato la 3.29

V3.29 2nd Feb 2006
Impulse response import now accepts WAVE files as well as .pcm files. Format must be Signed PCM, with 16, 24 or 32 bits per sample. If the file is multi-channel can choose which channel to import
Impulse response export now offers choice of 16, 24 or 32 bits per sample with/without normalisation and allows two channels' responses to be exported as a stereo WAV
Added controls to the Impulse Response Controls page to re-scale the impulse response to achieve a desired peak SPL figure in the frequency response
Added selector to display the full range Energy-Time Curve in place of the impulse response with adjustable smoothing
Changed shortcuts to allow Alt+1,2 etc to select the channel, Ctrl+1,2, etc to select graph group and Ctrl+Shift+3 to apply 1/3rd octave smoothing. The number for each channel appears in the channel's tab
Shortened the default names for the surrounds to SL, SR, SBL, SBR (use Restore Default Names to apply them) so that the tabs fit within the default width of the app on startup
Added an SMS-1 equaliser setting
Added an overlay capability to the waterfall plot with variable transparency
Added measurement notes for each channel accessed via View -> Measurement Notes or by right clicking on a channel's tab in the filters pane. Notes are saved/restored with measurement data sets and are also shown in italics in the tool tip for each channel's tab in the filters pane and in the file chooser preview for mdat files.
Filters tab text is black if channel has data, grey if not
No longer restore initial mute states on exit to avoid possible feedback loop if Line In was not muted in replay volume before startup

Bug Fixes

IR window extent lines were drawn one pixel offset to the right
Spectral Decay and Waterfall data were not cleared when a new data file was loaded
Incorrect limits checking on some of the values of the Set Extents dialog
Trace generation could produce index out of data range
Help topic link broken for bfd midi configuration

Thanks John !

[vilnius]

Io ci provo e vi chiedo: ci scrivete poche righe su come utilizzarlo (bene) per capire la risposta in frequenza del nostro sistema audio e la successiva calibrazione?
E' sufficiente un fonometro tipo radioshack ?
