Beta Test: Multitone Loopback Analyzer software

[pkane]

Multitone Analyzer v1.2.19 is now the officially released version.

Changes in 1.2.19​

• Add: support to save test signals in DSF (DSD) file format, up to DSD1024
• Add: support for reading and displaying spectrum for DSF (DSD) files if dropped into the spectrum window
• Add: option to play and generate DSD test signals with bandwidth not limited by the DSD base rate (Test Signal/DSD Gen multiplier setting)
• Add: a 7th order DSD modulator option (previously 6 was the maximum)
• Add: arbitrary low-pass and high-pass filter option to the test signal specification

I note from one of your earlier posts that task manager doesn't show anything.
Something has to be using resources though - but this kind of issue is difficult to diagnose remotely.
Have you tried loading the bios defaults?
Are you running on battery or mains power?

I would try setting the Power Mode to "Best performance" in Settings or select the High Performance or Ultimate Performance power plan instead of balanced.

What is this

Wdf01000.sys
High isr and dpc

Thanks

Stuff like that usually have to do with power plans if I remember correct another thread.
What's your power options at this time?

Try the following:

Open Command Prompt as an administrator (right-click the Start button and select "Command Prompt (Admin)" or "Windows PowerShell (Admin)").
Run the System File Checker by typing sfc /scannow and pressing Enter.
Run the Deployment Image Servicing and Management (DISM) tool by typing DISM.exe /Online /Cleanup-image /Restorehealth and pressing Enter.

Both of these will take some time to complete usually. Once they're done, reboot the computer.

Thanks, I did it. Still the same problem.
By the way, I ran the latency monitor on another windows 11 computer that has no issues with the cosmos and the bad remark of latency monitor appears on the other computer as well although no problems with cosmos or playing music

Hi Paul,

I tried to test the DSD function of the MTA (1.2.19). The DAC is set to ASIO while the E1DA COSMOS ADC to WASAPI.
Put short FFT length like 1k and DSD native up to 512 is working in the sense that in the preview window I see the test file (e.g. 1khz) but at the end, at the main analysis windows nothing, basically noisefloor, same from DSD 64 to DSD 512. What do you think I am dpoing wrong?

Hi Guy,

Can you post a screen shot with all the settings?

 

[Guy.Cohen]

Hi Guy,

Hi Paul, here are the setting. Except that it is offline. I am using Singxer DAC as source, so ASIO driver for DSD. For the ADC I am using E1DA WASAPI exclussive. In the setting I also check the wasapi exclussive, but even if I unchecked and then using shared for the E1DA ADC it does not help.

You can see I put native and DSD mutiplier 256 but also others like DSD 64 not good. I am using short FFT but this is not the problem. The modulator order also does not help

Sometimes for some reason I do not undertand it works but reasding is not stable, I tried another PC, same issue. It happens with my Singxer SDA 6 PRO2 and with SMSL DO300EX

Thanks,
Guy

Hi Guy, can you try base 44.1k DSD rate, instead? Many (most?) audiophile converters don't implement the 48k-based DSD rate correctly.

You are right! Thank you.

Having a problem with latest MT SW. Been using it for quite a while very successfully. I use it with an RTX6001 audio analyzer as the ADC/DAC via RTX ASIO driver. Currently it will not output any test signal to my RTX DAC. The input measures the noise floor of the unit under test. My other test SW (Virtins and SpectraCal) work just fine still. I tried to install an old version but I get the same issue. Is there a way, besides using uninstall, to completely delete the program? The reason I ask is even when I install an old version it starts up with my previous settings. Im guessing a old config file is being stored somewhere that I would like to delete.

You can delete or rename the following file to set the default settings without removing the program:

C:\ProgramData\Multitone Analyzer\_MultitoneDefault.dw

Multitone must be closed before altering the file!

Programdata -folder is hidden by default, but you can paste the path to access it...

 

[dougggoldberg]

They did it. I deleted the config file and reinstalled. All is well. Many thanks!

Hello Would it be possible to save separate L and R files for different "cal" settings in the future?



Even if it's just for convenience, as a simple shortcut...

an elegant way to access the "cal" selection by right-clicking on the small "cal" icon in the bottom bar, allowing for instant display changes...

Example of use:
Compare the impact of different "cal" settings (hpn, heq, no cal, etc.) on headphone measurements. If you clarify my request for this feature ( like cal left/right different..Heaphone measurement benches offer two distinct left/right "cal" values, for example...)

and perhaps more important
allow us to keep the number of "ave" if we only change the "fft size" or "gain" and not systematically revert to "1",especially since it resets to "1" at the time of measurement

And a classic smoothing functions like in Rew?
"Multitones can also be used in acoustics"
;-)




Happy new year

Hi @morillon, and happy New Year to you too!

Sure, I see you're trying to use MTA for more acoustic measurements. My intention was never to compete with REW but to find simpler ways to measure electronics. I can certainly add some acoustic-related functions. ERB smoothing, for example, was something I already wanted to add, especially where it involves frequency response and noise floor measurements. Let me think about it.

> allow us to keep the number of "ave" if we only change the "fft size" or "gain" and not systematically revert to "1"
That seems to be a bug when changing FFT size. I'll fix it.

 

[morillon]

Sorry for my writing... I hope my point is somewhat clear. :-0
(While using the headphone measurement bench addressed somes minor needs ..I had regarding file "cal" management.. L and R , not juste one... the rest is really for general use...In practice acoustic, if a smoothing treatment is somewhat versatile, it's generally 1/12 or var...But in electronics, a 1/24 or 1/48 scale will probably be quite sufficient (?))

 

[morillon]

What I find sometimes practical is being able to modify the display of a previously measured FR curve by manipulating the "cal" files... without having to retake the measurement...
which I'm probably not expressing very well. :-(
(One of the features of REW that I find always impresses me a little is its ability to extract detailed distortion data during log chirp analysis.even though in acoustics one might require long chirp, seen and repeated to be relevant)

 

[morillon]

Hey...
why did I use MT here and not rew for this use.. ?
it's because fundamentally MT (like Virtins) is comfortable handling differentiated ADCs and DACs, (even at different resolutions) not REW
Thank you mr pkane...
;-))

 

[morillon]

Ps an 1/12 or erb for "acoustic use" , and a 1/24 just for "clean" in electronic is probably enough
;-)
( and a small 2sigma for w&f?)
;-)

 

[morillon]

The idea isn't to replicate the core functionality of software as different, powerful, and polished as REW...
but in practice, there are points where you think, "Wow, this is really missing..."
There's one obvious and necessary comfort feature that seems to be absent in MT, which makes REW comfortable:
the ability to easily and independently adjust a given scale (X or Y) using a simple "+-" motion, rather than scrolling proportionally to both (or having to manually redefine the X-Y window).

It makes all the difference in practice.
