Welcome toBodzioSoftware Pty. Ltd.: We are based in Melbourne, Australia and have beendeveloping loudspeaker system design software for personalcomputers since 1990. This site is intended to provideinformation about our WinXP™ program: BoxCad,and Windows7/64bit and Windows10/64bit programs: SoundEasy and UltimateEqualizer.='3'>

“An Interview with NevilleThiele” - By Steve Mowry,Voice Coil 2006.

We can provide you with comprehensive Subwoofer Box Design Software for creating a high performance bass box. Build a ported box, sealed box for your low-frequency speaker. Make a subwoofer enclosure plan. Calculate speaker box volume, port length and other parameters without getting confused in formulas. This AutoCAD tutorial is about basic 3D modeling with some easy command, Check it out!!! Term-PRO Loudspeaker Enclosure Design Software Video Tutorial. Transmission line speaker box design.

“…SM: What do you see asthe trends in loudspeaker design and development in the next tenyears?

NT: Active loudspeakers with equalization,lower crossover frequencies, and more nearly omnidirectionalradiation. Theymay not be trends but seem to me a better way of doing things….”.

Introducing the Ultimate Equalizer='#800000'>

Exampleof The Ultimate Equalizer System Configuration Screen (BBM+CABS)

Majorcharacteristics of Ultimate Equalizer system are

Active system – allows amplifiers to exert maximum control over loudspeaker driver and makes crossover characteristics independent of driver loading.

DSP crossover and voicing – maintains crossover and voicing characteristics with mathematical precision.

Amplitude and phase HBT equalization – results in flat amplitude and phase responses and extends bass response.

Linear phase – maintains 0deg acoustical phase response of each driver, which results in transient-perfect system for correct spatial imaging (realism, depth, resolution, ambience) for multi-channel sound reproduction.

Minimum-phase/Linear-phase room EQ – removes most obnoxious room modes.

Available with BBM bass management and CABS active suppresor of room modes.

Remote control – via 2.4GHz wireless keyboard and mouse.

Built-in WAV Player - with this option, there is no need for any sound cards at all. UE will create and play 'playlists' with the standard CD-style WAVE files (16-bit/2-channels/44.1kHz) using motherboard codecs.

And also Hi-Res WAVE files 24bits/2-channels/96kHz and 24bits/5.1-channels/96kHz using motherboard codecs and digital add-on sound crads.

Use Windows Media Player, or install other Media Players – to create audio server and state-of-the-art loudspeaker management system (user-friendliness, power, flexibility, cost efficiency and sound quality) on one HTPC.

Removes 'flabby' or 'woolly' bass and provides linear-phase bass as commented by:

1. Michael Gerzon “ The subjective effect of phase compensation of the bass from loudspeakers is very marked, giving a much tighter and more 'punchy' quality, with greater transparency, and interestingly a subjective extension of bass response of at least half an octave. The improvement is audible even on loudspeakers with a very high cut-off frequency, such as Quad electrostatic designs. . . . The benefits of bass phase equalisation are considered, by those who have heard itt, to be a substantial improvement over what was hitherto possible with analog technology, and digital equalisation provides a way of improving bass performance without going to ridiculously large giant space-consuming power-hungry monster speakers, and is certainly a much cheaper route “.

2. Keith Howard “As I pressed Play, I didn't know what to expect: a mild improvement or a revelation. To use a curry-house analogy, I was half-prepared for korma rather than phal. But when I compared the unprocessed and phase-corrected tracks, it took only a few seconds of the latter to persuade me that here was a significant improvement. Just as Michael Gerzon described, the phase-corrected sound was both weightier and punchier, and distinctly more coherent. It simply sounded more like a bass guitar, to the extent that I almost hummed along—not something that I would normally expect to do when listening to a bass-guitar accompaniment shorn of all else (sorry, John), and certainly not an urge I felt with the unprocessed track. Still, time-consuming as it was, this experiment involved only a single music excerpt and was conducted in mono, and so hardly offers a comprehensive insight into the full benefit of bass phase correction. But what I heard convinces me that this is an area in which the application of DSP can make a significant contribution to fidelity.” Source: http://www.stereophile.com/reference/706deep/index.html

Ultimate Equalizer V10 has been released.....

For full description of the program features,please download PDF manuals below. This release is recommendedfor i7-960, 3.2GHz or better processors. Please note, thatour software is periodically reviewed and fixes are implementedas an ongoing process.

List of improvements in Ultimate Equalizer V10.0

1. The size of project data files is reduced to half of the V9 size. This is quite substantial change, and allows for faster loading of project files.

2.MLS system uses WASAPI 16bit/24bit drivers instead of the legacy WDM/MME drivers.

RoomEQ measurements use WASAPI 16bit/24bit drivers instead of the legacy WDM/MME drivers.

Added second version of the BBM system. The FL channel is independently filtered and summed with Left Subwoofer, and FR channel is independently filtered and summed with Right Subwoofer.

Current Bass resolution settings (buffer-size dependant) are displayed on MLS transfer function screen.

Bit depth on the input-side can be set to 16bit or 24bit. Many contemporary motherboards only allow for 16-Bit depth on recording side due to compatibility with CD recordings requirements.

MLS system uses the same impulse response files as SoundEasy V21. The UE10 and SoundEasy V21 programs are compatible for impulse response measurements.

WASAPI Debug Mode. Useful to debug sound card drivers implementation.

Automatically appends buffer size and sampling frequency to driver’s filename. Also, appends sampling frequency to impulse response filename.

10. Compiled and tested on Windows 10/64bit.

The UE includess inverse-HBT equalization, time-inverse processing that eliminates phasedistortion, crossover filtering, and partitioned convolution.Equalization of the individual drivers’ response to the userspecified acoustic target is performed automatically with theclick of a button. The outcome is a transient perfectspeaker system with flat amplitude and phase responsesthat faithfully reproduces any input signal relative to thedesign point, as demonstrated by the ability of thespeaker system to play undistorted square waves.Shelving and notch filters are included to voice the speaker toother than ruler flat response and the time-inverse processingand be switched on or off as desired. Recommended sound card isLynxAES16 and Delta1010LT (capable of WASAPI technology inExclusive Mode). This stand-alone, fully self-containing programincludes ALL functions, that you need to createyour 'DSP-on-PC' system. The UE-PC incorporates RoomEqualizer and large 5.1 Home Theatre option (8in/16out).The program includes self-starting option, so you can arrangeyour PC to start running UE on power-up, and thus have the wholeprogram up and running by pressing 'Power ON' button onyour PC case. Latest release includes 19-function remotecontrol via wireless keyboard.='#ff0000'>

SoundEasy v26 has been released......

SoundEasy + EasyLab system is acomplete modelling and measurementsoftware package. ( for full description of the program features, pleasedownload the PDF manual below )

SoundEasyoperatesin time and frequency domains and models the complete design andadvanced (Phase/SPL/Zin - constrained)optimisation process of multi-way loudspeaker system, includingWMTMW arrays. The program allows for a complete characterisationof all drivers, including complex transfer function for soundpressure (amplitude frequency response) and input impedance. Directdata import functions from PC-based measurement systemsare included. SoundEasy will even tell you if your imported phaseis correct and will help you to correct it (using Hilbert-BodeTransform, HBT, during the import). Enclosure design includes13 types of enclosures,including H/U Dipoles and handlesmultiple driver configurations. Up to 4 identical drivers can beplaced on the front panel to analyse diffraction distortion andmutual radiation impedance.Large-signal analysisisprovided and includes: BL(x) and Cas(x) non-linearity, portcompression and thermal power compression effects. OurNEW, full-screen, scrollable,re-sizable CADsection of theprogram, handles all electronics of the passive/active systemsuch as: complete and detailed passive or active crossoverdesign, and time/frequency/impedance compensation circuits. TheCAD system allows you to include advanced DSP components, like LinearPhase Filters, Time Delay Elements, andour own Super-Components, Mega-Componentsand Modular Crossover concepts, none of which can beimplemented in standard, passive crossovers. 100 of popularfilter/crossover types are built-in. Finally, complete systemresponses are obtained by taking into account mutual 3D alignmentof the drivers on the front panel, includingoff-axis simulations, tiltingand rotating drivers. As theRay-Tracing Methods are really not suitable for low-frequency(below 300Hz) room modelling, we have implemented extensiveevaluation of room and car cabin acoustics using Image Method andthe powerfulFiniteElement Method for complex room geometries - ideal for 4sub-woofer placement evaluation, including two dipole subwoofers. The FEM includes modelling ofabsorption at each node and allows you to include openedwindows, carpets, heavy drapes, (any size) etc. in youranalysis. The program is quite large. It contains over 80plotting screens/control boxes for modelling various designprocesses and a number of 'calculators' for performingspecific modelling functions. There are also numerous dialogueboxes for customizing plotting and display functions. The programincludes support for design and optimization of Transient Perfectcrossovers. Small-Thiele loudspeaker model has been expanded byusing FEM to model enclosureresonant modes. Non-Coherence Analysis is included and Minimum-Phase Extraction is based on iHBT and Curve-Fitting Algorithm. Peak Power Dissipation ratio displayed.='2'>='#000000'>='#000000'>='#000000'>='#0080ff'>

DSPFunctions

1. CAD-based Digital Equalizer has been implemented to enable perfect filtering withsimultaneous equalization of ANY irregularities of SPL responsecurve. This has been accomplished by modifying the targetedfilter transfer function by the inverse SPL response of thedriver, and at the same time cancelling the parasitic'tails'of the SPL using Hilbert-Bode Transform. OurEqualizer allows you to audition your favorite audio-CD via thesound card and also includes simulating propagation delays due todifferent spatial location of the acoustic centers of drivers.This feature is significantly more advanced than typical DigitalFilter - see SoundEasy Reference Manual, Chapter 9 for details.Filters and Equalizers up to 2x4-way can be constructed andevaluated with suitable, MME-compliant sound card.='2'>='#ff0000'>

2.Digital Room Equalizer (DRE) allows you to step out of the loudspeaker box anddo something constructive with your room acoustic. The DRE is aHBT-based, minimum-phase equalizer, designed to put 'finaltouches' on your room transfer function. It includesfull-screen SPL pixel editor for precise modifications to yourmeasured SPL curves and other processing tools. Please seeSoundEasy Reference Manual, Chapter 19 for details. Will run onmost 16-bit, full duplex, stereo sound cards.='2'>='#ff0000'>

3.System Phase Equalizer works with already built loudspeakers and allows you toremove all phase delays due to enclosure and crossover frequencyresponses. Loudspeaker equalized this way will reproduce squarewave reasonably well, depending on amplitude irregularity. Pleasesee SoundEasy Reference Manual, Chapter 19 for details. Will runon most 16-bit, full duplex, stereo sound cards.='2'>='#ff0000'>

4.Advanced System Phase Equalizer. In addition to (3), the Advanced System PhaseEqualizer also equalizes the amplitude response of theloudspeaker system. When operated with a loudspeaker system, youwill be able to flatten the amplitude AND phase of the completesystem. Loudspeaker equalized this way will reproduce square waveperfectly. Please see SoundEasy Reference Manual, Chapter 19 fordetails. Will run on most 16-bit, full duplex, stereo soundcards.='2'>='#ff0000'>

5.Bass Synthesizer. This is a sub-octave bass synthesizer generating firstsub-harmonic of the lowest bass note present in the musicmaterial played through the synthesizer. The resulting bassoutput is user adjustable and is perfect way to give yoursubwoofers something to do. You can also write your own WAVfiles, while the bass synthesizer is working, so you can modifyyour favourite music, giving it tonal balance of your choice.Please see SoundEasy Reference Manual, Chapter 19 for details.Will run on most 16-bit, full duplex, stereo sound cards.='2'>='#ff0000'>

6.Digital Filter (FIR implemented as Fast Linear Convolution, and alsoas Partitioned Convolution ) function has been provided forauditioning your crossover design via sound card. Ourimplementation includes simulating sound propagation delays dueto different spatial location of the acoustic centres of drivers.You can also write your own, and read WAVfiles. Please see SoundEasyReference Manual, Chapter 9 for details. Filters and Equalizersup to 2x4-way can be constructed and evaluated with suitable,MME-compliant sound card.='2'>='#ff0000'>

EasyLab - Advanced is an expanded section of the SoundEasy program,dedicated to frequency and time domain measurements of the driverand room acoustics. The system incorporates digital (MLSand pre-emphasized MLS) and analogue (ESS) measurement system thathas been implemented for measuring SPL and Zin. Both methodsinclude powerful post-processing functions, including amplitude/timezoom-in on Impulse Response, scroll ImpulseResponse and analog input buffer, HB Transformfor easy determination of acoustic center of thedriver. Dual Channel Oscilloscope with built-in6 signal generators: Sine Wave, Square Wave, Pink Noise,White Noise, Two-Tone and Tone-Burst.Next, Spectrum Analyser with various screencontrol option (including WarpedFFT), THD display, and the sameset of signal generators. Cumulative Spectra Decay (CSD)Analyser now includes Tone-Burst Waterfallsas well.There is also a Small-signal(T/S) and Qb extraction screen using Delta Mass andDelta Compliance methods, RLC Measurement screen,Distortion Analyser, including estimation ofnon-linear coefficients of BL(x), K(x) and Le(x)using truncated Volterra series expansion method, and finally,advanced Non-linear Parameter Measurement screenand modeller based on driver's differential equations andnumerical differentiation. EasyLab employs extensively MLS-typeof test signals, Hilber-Bode Transforms and curve-fitting methodsin it's measurement system. 'Curve Arithmetic'function for Digital and Analogue measurement functions is alsoprovided. Your SPL field measurements can be saved as a raw-datafiles, so that you can perform all post-processing andpresentation functions later, at your convenience - see SoundEasyReference Manual, Chapter 16 & 17 for details. Tone bursttesting method is also implemented. The next addition to theEasyLab system is RT60 measurement capability.The system incorporates Schoeder Backward Integrationand two methods for noise reduction: Truncated andSubtracted. THD/IMD measurement system and Cepstral Deconvolution have been added recently, and finally, a Matching Filter Techniquehas been implemented, in this release. CepstralDeconvolution and Matching Filter Technique both allowreconstruction of measured, echo-contaminated, low-frequencyresponse of a loudspeaker system. Non-Coherence Distortion analysis, CSD Differential plots and Large Signal Impedance Measurements are the latest additions to EasyLab section.='2'>='#ff0000'>='2'>='#ff0000'>='2'>='#0080ff'>='#0080c0'>

BoxCadisa sophisticated software tool (separate program) focused onenclosure analysis using acoustic impedance models and electricalimpedance models - highly recommended for advanced designers. 10models are built-in for your convenience, but you can letyour imagination fly and invent an esotheric enclosure andanalyse it using BoxCad -unlike using other loudspeakermodeling programs, you are NOT restricted to built-in enclosuremodels. Again, frequency and timedomain analysis is available. The results of the analysis can becombined with active/passive circuits designed with built-inelectronic CAD system. And yes!, you can model PassiveRadiator Band-Pass enclosures of any type with BoxCad.If you are concerned with vent non-linearitiy during turbulentflow - perhaps PR system will satisfy your requirements. And howabout an Acoustic Cannon ?.='#000000'>='#0080ff'>

Pokegen For Mac High Sierra

MacOS High Sierra (version 10.13) is the fourteenth major release of macOS, Apple Inc.' S desktop operating system for Macintosh computers. MacOS High Sierra was announced at the WWDC 2017 on June 5, 2017 and was released on September 25, 2017. In this article, I am going to give you the direct link to Download macOS High Sierra ISO DMG VMDK File – All In One. Whenever you want to install macOS High Sierra on virtual machines like VMware and VirtualBox then obviously you will be in need of ISO file in order to have a clean installation of macOS High Sierra.

More than four years ago, Alicia Katz Pollock wrote “Five Ways to Reset a Lost Administrator Password” (17 January 2014), and through the vagaries of Google’s search algorithm, it remains our most popular article to this day. Apparently, lots of people forget their macOS passwords or need to help friends or clients who have lost their passwords.

Unfortunately, that article is long past its shelf life, so here’s a current guide to resetting an admin password in macOS 10.13 High Sierra. As before, you can accomplish this task in a variety of ways, depending on how the Mac in question was set up and what information you know.

Reset the Password from Another Admin Account

The best-case scenario is that there is another admin account on the Mac for which the password is available. If that’s true, you can log into that account and change the password for the locked account:

Open System Preferences > Users & Groups.

Select the locked account in the list at the left. (If necessary, click the lock at the bottom of the window and provide your admin credentials.)

Click Reset Password.

Enter the new password, verify it, and (optionally) include a password hint.

Click Change Password.

The only problem with this method is if the locked-out account is logged in, you can’t modify it. The easy solution is to restart the Mac, log in with the admin account whose password you do know, and carry on from there. To forcibly log out the other user while rebooting, you have to enter an admin username and password.

If you don’t currently have an extra admin account on the Macs you take care of, it’s a good idea to create one. Just make sure it has a strong password that you’ll remember.

Reset the Password Using an Apple ID

What if there is no other admin account available? You can use the Apple ID associated with the account in question to reset the admin password, but only if these conditions are true:

You know the Apple ID’s email address and password. If you don’t know the password, but you have access to the email address, you can reset the password at Apple’s Apple ID page.

The “Allow user to reset password using Apple ID” checkbox in System Preferences > Users & Groups must be selected. This setting won’t appear if FileVault is enabled.

To get to the point in the login process where you can reset the password, click the question mark that appears on the right side of the password field or just try to log in three times. After the third failed login attempt, the Mac will prompt you with the password reminder, if one is set, and give you the option of resetting the password using your Apple ID.

Then enter the Apple ID email address and password and follow the onscreen instructions.

Reset the Password Using the Reset Password Assistant

If the “Allow user to reset password using Apple ID” option isn’t enabled, or the previous method doesn’t work, there’s still a way to use Apple ID credentials to reset the admin password. You’ll need to use Apple’s Reset Password assistant, which requires that you reboot into macOS Recovery and use Terminal:

To enter macOS Recovery, restart the Mac. As it’s starting up, press and hold Command-R until you see the Apple logo, at which point you can let go.

Once in macOS Recovery, ignore the main window and choose Utilities > Terminal, which opens a Terminal window.

In that window, type resetpassword and press Return to open the Reset Password assistant.

Either way, once you’re in the Reset Password assistant, select “I Forgot My Password” and click Next.

If the account for which you wish to reset the password is a standard account, rather than an admin account, all you have to do is enter a new password.

For an admin account, you’ll instead have to enter the password for the account’s associated Apple ID. (If you don’t know it, you can click “Forgot Apple ID or password?” to move on to the Apple ID recovery process, which may require your trusted phone numbers.) Once you have entered the necessary password, you may be prompted for a two-factor authentication verification code, which will arrive on another device connected to that Apple ID. (If the Mac is your only Apple device, you should be able to receive the code from a phone call or SMS text message.) Finally, you’ll get to a screen where you can enter a new password and password hint.

What If You Use FileVault?

FileVault encrypts the Mac’s boot volume, making it readable only after the appropriate login credentials are entered, typically those of the primary admin account. The process for resetting the admin password changes a bit if FileVault is turned on because FileVault eliminates the option to reset the password with Apple ID credentials.

Fortunately, the method remains simple: enter a random password three times at the login screen, after which you’ll be prompted to reset the password using your Apple ID or recovery key.

Apple notes that you may still have trouble logging in with the new password after all this, and if so, suggests that you use the Reset Password assistant to reset the password again, using the “My password doesn’t work when logging in” option and following the subsequent instructions.

I hope your FileVault recovery key is stored in a safe place, like 1Password or LastPass! If it wasn’t saved or you can’t access it, you may want to turn off FileVault before you get into a situation where you can’t log into the Mac. In my experience, it’s easier to back up the drive, erase it, and then restore it, than it is to turn off FileVault.

Dealing with the Keychain

The keychain is an encrypted container associated with each user account that stores login credentials for apps, network servers, AirPort base stations, and Web sites accessed in Safari. It’s easy to forget about the keychain because it is typically protected by the same password used to log in to the account. As a result, resetting the password for an admin account means that you can no longer access the keychain for that account. Sorry, but there’s no way to recover that information.

Pokegen For Mac High Sierra Leone

After resetting the admin password and logging in again, you will likely receive an alert that macOS was unable to unlock your login keychain. Click Create New Keychain to start fresh. If you don’t receive the alert and have problems with the keychain, follow these steps to reset it:

Open Keychain Access from /Applications/Utilities.

Choose Keychain Access > Preferences and click Reset My Default Keychains, which creates a new keychain with no password.

Log out of the account by choosing Apple > Log Out Username.

Log back into the account to tie the account password to the new keychain.

Don’t Reset Passwords Willy-Nilly

As you can see, there are a variety of ways that you can reset a lost or forgotten admin password and regain access to a Mac, although they all depend on knowing either another admin password or an Apple ID password.

However, don’t reset an admin password unless doing so is absolutely necessary because the login keychain will be lost in the process, and that will likely cause future annoyance.

Pokegen For Mac High Sierra 10.13

If you’re not yet in this situation, take precautionary measures now! Be sure that your Macs’ passwords and any FileVault recovery keys are stored in secure locations that you—and other trusted users—can access easily. And of course, make sure to keep regular backups, which can help you recover from a multitude of sins.
