Beta Test: Multitone Loopback Analyzer software

Are you sure that you uploaded the correct version?

ENOB is still wrong too:

I think so, but just re-uploaded it again. Looks like you were still on the old version...

I checked the compilation date inside the zip of your previous upload, it was about 21 hours old so the re-upload helped!

Now the link is right:

makes the correct output:

ENOB is fixed too with the calibration file:

And channel and channelNumber too:

Thanks a lot!

Would it be hard to change the code to open the "New variable" -line below the "Harmonics" -line and not the above of it?

It would make all your own rows to be neatly at the bottom of the list and not sandwitched between the "Harmonics" and all the rest...

And could the DC-offset from the Spectrum -view be added to "Results" -window too:

I'll spend more time on where the new variable is added. For now, it's next to the last to allow the enter key to be processed properly. When it is on the last row, the enter key has no effect, and to me, that's really annoying I'll see if I can figure something out in the future.

Of course, I can add DC, but now so can you Just use the {dc} variable (or dc1 or dc2).

Thanks!

Please pay attention to this behaviour too:

If you have ticked only your custom variables visible...

... and you add another one, all the lines come visible without ticking them on:

Note the "ticked on" harmonics, which wasn't selected before! And your new variable (test2) isn't selected...

Of course, I can add DC, but now so can you Just use the {dc} variable (or dc1 or dc2).

Ooh, a hidden feature! Does this mean, that I'll have to try to find all of them?

@pkane something have to be still done with the initialization of variables when using the single channel measurements.

There will be problems with the calculations that are meant for the two channel measurements (Like the averages etc). This is right after the restart of MT before any measurements because there is no intial values for the second channel variables:

And this is after one LEFT -> LEFT measurement, still no initial values for the second channel:

If the second channel variables were changed to zero at the startup then the error is gone but the averages would be calculated incorrectly:

Would it make sense to copy the first channel values to the second channel when using single channel measurements (But of course not mark the current measurement as a two channel measurement)?

It does look a bit ugly, but to me an error message indicating there's no value is better than using the wrong value and not saying anything. Maybe we can come up with a better way to indicate the value is missing...

You can, sure I just added documentation for a few other missing variables: https://distortaudio.org/multitone-exp.html

• dc
• tones
• crest

Ok,I won't bother you with charts and it's a little off MT.
I played with EAPO the last days.
Installed it (for the second time),set it up nicely and I only corrected 4 freqs,all below 250Hz.
Did a measurement the whole chain and it was a mess!Specially multitone measurements (32 tones) were 10db down!
Clicking it off everything comes back to normal.
Does this makes scene?

What do you mean 10db down? The level of the multitone was 10db lower than without EAPO? Any EQ can affect the overall level, but a lot depends on the engine and what EQ you apply.

I mean worst SINAD and stuff.Lots of grass,elevated noise,etc.

I will never install it again in my life,I even cleaned-up registry and everything that even reminds it!

And that's the second frustration for today,the first was that the fuel regulator's sud pressure hose of my car got a hole and was hissing like @Holmz 's PA5.

Easy to find it then

Sounds like you need to get back to breaking Multitone, then! That should reduce frustration and make you happy!

What is multi tone hiss?
It is not pink, so maybe it is brown noise?

I left a speaker cable in front of the speaker and in the dark last night, I thought it was a brown snake.
Which are pretty dangerous…

King Brown Snake (Mulga) - Australian Reptile Park

Despite its common name, the king brown snake is not a true brown snake but one of the black snake family.

The bastards can dump over a half cup of venom into their victim/prey.

I've been trying to!
But other that some hung-ups,2 freezings and some history stuff (Sokel's way) which were random I had nothing to report.

Brown multitone isn't as hissy, I think. Maybe blue?

Or purple?

I'll work harder to mess things up for you. Can't have a master breaker getting frustrated on the job, now can we?

 

[Sokel]

Ok I have one but it's maybe me or the function of the sample rate.
(I measured a nice analog thing)

That's 44100 going smoothly:

...but what is going on with 96000 sample rate down there???
