MOV | 32.81 MBHar-Bal is the software that introduces the concept of Harmonic Balancing and the means of achieving it. In this section we introduce the software and the process of Harmonic Balancing as implemented through Har-Bal. Before continuing and further, I thoroughly recommend that you first read the Har-Bal introduction as you will learn a great deal about the structure of the software, its capabilities and the thinking behind its implementation.
1. Filter related toolbar buttons
These toolbar buttons allow you to open, save and create new filters for the track being harmonically balanced.
2. Reference related toolbar buttons
These toolbar buttons allow you to open, close a reference track or reference track analysis and swap a playable reference with the current track being harmonically balanced.
3. Filter design undo/redo toolbar buttons
These toolbar buttons allow you to undo and redo filter design changes.
4. Playback/Record control related toolbar buttons
These toolbar buttons allow you to playback and/or record the current track with or without the filter in circuit.
5. HB Air, Filter, Dynamics and Reference control toolbar buttons
These toolbar buttons allow you to switch HB Air in and out, switch the filter equalisation in and out, switch dynamics processing in and out and switch the reference track playback in and out.
6. IntuitQ and IntuitMatch toolbar buttons
These toolbar buttons apply the IntuitQ and IntuitMatch algorithms to the spectrum content of your track, with the frequency range of application being determine programatically.
7. Filter editing and view control toolbar buttons
These toolbar buttons let you control the graphical view and design the Har-Bal filter.
8. Time line control
This control cue the track playback to the desired position, select looped playback, create and select track segments, navigate through segments and select segement references.
9. Time display
This display shows the live time in seconds of the track being played.
10. View Selection Tab
This tab controls is used to select between Sprectrum, Frequency Response and Histograms views.
11. Spectrum selection dropdown list
This dropdown list allows you to select the spectrum to view and design a filter for. It is one of Mid, Side, Left or Right.
12. Average power figure of merit indicator
This indicator displays the un-weighted average power figure of merit for the current track without any processing. This value is relative to the power of a full-scale square wave.
13. Processed figure of merit indicator
This indicator displays the un-weighted average power figure of merit for the current track with dynamics processing and applied gain. This value is relative to the power of a full-scale square wave.
14. Volume control slider
The volume control slider can be used to change the playback monitoring level. This has no effect on recorded levels.
15. Spectrum view
The spectrum view shows a graphical representation of the overall energy content of the current and/or reference track. The spectrum display shows the average spectrum, the peak spectrum and the real time spectrum for the track. We make use of the spectrum editing tools to design Filter equalisation schemes.
16 Limiter gain control slider
This limiter gain control slider allows you to apply a gain to the playback and/or recording of the current track. This is typically used for normalising track levels. This gain is on the input side of the integrated Har-Bal limiter, which limits the final output to -0.5dB relative to full scale.
17. HB Air control slider
This HB Air control slider allows you to apply the HB Air effect to the recorded and played back tracks. This is typically used when your track lacks a sense of space.
18. Tips popup
The tips popup gives spectrum context sensitive clues to designing appropriate equalisation filters.
19. Status bar message area
This region of the status bar is used to report context sensitive help on menu items and toolbar buttons as well as general data values from the graphical views.
20. Cursor focus indicator
This indicator informs you which spectrum trace is being edited when using the parameteric and shelving cursors.
21. Limiter gain reduction meter
The limiter gain reduction meter gives a graphical indication of the amount of gain reduction being applied during playback by the limiter. The meter is a log scale meter (linear in dB) with full-scale corresponding to -15dB.
22. Spectrum resolution buttons
These buttons allow you to alter the resolution of the displayed spectrums. You can switch between 1/12th octave, 1/6th octave, 1/3rd octave and 1 octave resolutions.
23. Spectrum view toggle buttons
The spectrum view toogle buttons allow you to toggle on and off the average, peak and real time traces.
24. Spectrum view control buttons
The spectrum view control buttons allow you to toggle on and off the original spectrum, spectrum focus indicator, reference and segment reference traces.
