Beta Test: Multitone Loopback Analyzer software

[Sokel]

I feel it's slipping away, but I'm still trying for that raise... Here's the updated version 1.0.24. Please check your WASAPI Exclusive setting, as the meaning has changed. If a driver supports less than 24 bits in exclusive mode, a warning will be displayed. Let me know if you can get it to work with more than 16 bits in exclusive mode!

Changes in 1.0.24​

• Fix & Change: WASAPI Shared mode setting renamed to WASAPI Exclusive. The meaning was previously swapped
• Fix: Some ASIO drivers couldn’t be mixed with WASAPI or other ASIO drivers because each driver tried to open channels for input and output

No glitches at all in 1.0.24.
Well done!

Not the most important thing but the preview window is acting strangely since around 1.0.22 version
I sometimes gets a lot of distorsion jumps, especially once the averaging begins, but the good thing is that it's not appearing in the final result.
The fundamental is also wider from the base, but once in the result window, it's a clean line

Yes, the preview window was "deprioritized" in favor of supporting higher sampling rates on slower computers It is now updating at much slower rates, and I've decreased FFT size to 4096 from 16k, which lowered the resolution of the preview window.

Thanks @pkane !

This turned out to be even more painful than I anticipated, but I believe WASAPI exclusive mode should now work correctly at more than 16 bits/sample with drivers that support it. I've tested it with four WASAPI drivers, hopefully you can help test with some others. Windows audio is a mess, and unfortunately, the audio library I'm using made it even more difficult.

Changes in Multitone 1.0.25​

• Fix: WASAPI Exclusive mode now works with the best available bit setting (previously only supported 16 bits)

Doesn't work for me.The interesting thing is mixing them so I get this:

Following...

If I twist them I get this:

I hope something of the above is useful.
ASIO works great!

Are you sure your device supports being used through ASIO and WDM at the same time? I would be surprised if it did.

No,not sure at all,you're right.
ASIO works great,WASAPI shared too with some -10db better noise.

Device in use is an error from the driver. Either you have some other software using the driver already or the driver doesn’t support mixing two exclusive modes modes, which is likely the problem.

10 years old driver,is a miracle that even works!

The PCI versions of EMU interfaces have hardware DSP and CPLD (similar to FPGA, but simpler) to achieve true multiclient operation. The USB ones on the other hand don't. It is not only a driver limitation, but also hardware limitation.

I'll stick to ASIO or WASAPI shared then,thank you!

 

[Sokel]

At last I got the WASAPI (shared) fixed and was able to replicate the measurement of ASIO at the same level.

I was all about a silly connection to the balanced E-MU input,for a unbalanced output I should only have the tip and the ring connected in the balanced E-MU input.

I think I'm ready to measure people's stuff .

Just did a digital loopback test with Hi-Fi Cable and it works via WASAPI Shared, but not via WASAPI Exclusive

WASAPI Shared:

WASAPI Exclusive:

After that, I tested with FLEXASIO (ASIO between Multitone and FLEXASIO) and in FLEXASIO, I set WASAPI for Hi-Fi Cable: it works for both Shared and Exclusive, but Shared gives a better result than Exclusive (not buffer related as I get the exact same result with 64 or 2048 buffer)

FLEXASIO + WASAPI Shared Hi-Fi Cable:

FLEXASIO + WASAPI Exclusive Hi-Fi Cable:

My results. Digital loopback going through the Creative hardware mixer (What U Hear) and therefore not 100% clean.

ASIO

Exclusive, @pkane how about showing "exclusive" and "shared" in the drop down menu so that others don't need to mention it? Also eliminates the need to open the setting dialog.

Shared

For DS, I don't know, it doesn't work at all, including the Realtek with stock MS driver

The result is close enough to EMU's marketing material with RMAA tutorial (check attachment), indicating healthy hardware and decent driver.

Did you try to lower the gain for the clipping in exclusive mode? There are differences in driver processing between exclusive and shared modes.

I know!This way I understand I do it right.
That's from my manual:

Yeah, not sure about Direct Sound recording. I'll need to do some more testing on that, playback should still work. I'll do some testing.

Sorry about all the recent updates, but with your testing Multitone is becoming much more complete and stable app

I've fixed the issue with Direct Sound drivers (it was mostly with the output driver, not the recorder) - @bennetng .
Seems to work as expected in my testing, and behaves nearly exactly the same as WASAPI shared mode driver: version 1.0.26

Changes in 1.0.26​

• Fix: Direct Sound driver selector broken in recent updates
