Beta Test: Multitone Loopback Analyzer software

[Sokel]

Felt very useful today so I measured Khadas's filters.

EDIT: to be fair,that's not Khadas's filtrers,it's Ian Canada's filters contained in his controller.Default (and only one Tone1 has without the controller) is Apodizing (the bottom one in timestamps).

You guys are doing such a great job of testing new versions! Let me run one more by you, see what you can find . Assuming the new features work and I didn't break anything new, this will become the next official release:

https://app.box.com/s/qbrh3czrvudclkqs9n8lm806k3hzmjx5

Changes in this one (v1.0.40):

• Added support for multi-channel input devices (WASAPI and ASIO) -- please test!
• Cleaned up multi-channel support in output devices from previous version
• Added cool-down setting for sweeps and repeated measurements
• Fixed the waveform plot to scale both graphs correctly when mixing different sampling rates
• Added settings panels to waveform and frequency response plots

Wait for it!

That pretty much describes my development process: find a way to do it wrong 100 different ways, then fix it

 

[Sokel]

Nope.
This time you must have broken it Sokel's way

 

[pkane]

Wow. That's not good Back to the drawing board...

Nice round number, no? Looks like ASIO sample conversion is broken. Strange, as I tested it with different ASIO drivers on my side.

Wasapi shared is also VERY weird.

Can you post an example?

Uninstall it,wait a sec to put it back.

Does exclusive mode work with your driver? Can you try if it does?

Nope,but after I tested it wasapi shared works!
(ASIO still doesn't)

Yes, I see the issue with ASIO. I changed how sample conversion works to speed it up, but I see I broke it for anything but 32-bit floating point samples. I'll fix ASIO asap.

 

[pkane]

Let's see if this fixes the issue with ASIO (@Sokel ):

Seems ok!

 

[Sokel]

Cool-down works nicely.wave form too.
Pff...nothing broken so far,later!

Impossible!

Hi @pkane

just tested, but I don't know if it's the version from this post, or from you're following post and so an updated one.

So, with the same device than yesterday, and ASIO:
- I get it to work on inputs and outputs from CH 1 to 8, with just a strange thing: the warm-up (for 1, 2 or more seconds) is always like this, and the right signal appears just once it says recording

Measurements are OK though

- selecting CH 9 or more (I only had 14 this time instead of 22 because ADAT was disabled) gives this error:
