Inguz EQ/DRC

[JohnB]

Odd. I'll do some tests later today.

[JohnB]

Well, I've confirmed your findings. On a test with pick noise the mono single channel was approx 8 or 9dB quieter.

I would guess that it is a bug but that doesn't get us much further. Sorry I don't have a resolution.

[Apesbrain]

Well, I've confirmed your findings.

Thanks for trying it yourself. I solved the problem the "brute force" way: converted all my one-channel FLAC to "dual-mono" 2-channel. The files are no larger so I guess FLAC must record this using a flag rather than storing two identical channels.

Inguz stopped working - filetypes wont select

Hi,

Inguz stopped working for me about a week ago. I did a reinstall etc, rebooted LMS many times but with no success. I noted also that it had stopped writing to the log.

Elsewhere on this forum I saw a recommendation to check that the filetypes were set up correctly. When I try that I see that Inguz is only mentioned in one place, The MP3 setting looks like this:

MP3	FLAC	Disabled
	MP3	Native

It is possible to select Lame/InguzDSP from the FLAC entry but when I try and "Apply" that it jumps back to "Disabled".

Looking at the LMS log file I see that whenever I try and do that I get the following error message:

[19-11-23 23:19:08.0200] Slim::Utils::Misc::msg (1252) Warning: [23:19:08.0198] Use of uninitialized value in concatenation (.) or string at C:\PROGRA~2\SQUEEZ~1\server\HTML\EN\settings\serve r\filetypes.html line 38.

This is where my debugging skills run out. Can anyone suggest what might be wrong and how I fix it?

My setup:

Logitech Media Server Version: 7.9.1 - 1522157629 @ Fri Mar 30 12:17:59 WEDT 2018
Operating system: Windows 10 - EN - cp1252
Platform Architecture: 8664

Many thanks

[JohnB]

A couple of things to look at first:

You say that Inguz stopped working about a week ago. Were there any changes to your PC or LMS that you did around that time?

Inguz needs lame to be installed for Inguz to work with mp3 files, so please check that lame is installed for LMS. In Windows 7 lame.exe should be in the folder "C:\Program Files (x86)\Squeezebox\server\Bin".

[Apesbrain]

Interesting finding: Since updating my PC from Win 7 to Win 10, I can now see and control Inguz settings in Internet Explorer (11.535.18362.0 x64).

[firedog]

Just installed this. When I go to plugins>EQ>settings
I get
"Cannot initialize Silverlight: createSilverlightControl is not defined" This happens on all browsers, including Internet Explorer.

I do have Silverlight installed on the LMS server. What's missing?

Plus: How do I add my RC convolution filters? If I go to my Touch interface to Extras>EQ>DRC the only option that appears in "none". ????

Thanks

The Silverlight thing is very unpredictable. I don't depend on it, but instead access EQ via mobile app: Orange Squeeze or Squeeze Commander. You can designate your filter file in the app or on your Touch under "Extras > EQ > Settings > Room Correction". The file first needs to be on the server in the "C:\ProgramData\InguzEQ\Impulses" folder if Windows. May also need a server restart to see it.

[JohnB]

firedog,

Apesbrain has already covered much of this but ....

The Inguz browser interface is only functional with Internet Explorer (partly because only Internet Explorer supports Silverlight).

Silverlight needs to be installed on the same PC as the browser.

If you already have FIR filter files, for Inguz these should be 32bit wave files and the files should be copied to folders:

Windows: C:\ProgramData\InguzEQ\Impulses\

Ubuntu: /usr/share/InguzEQ/Impulses/
- Mine are set to Owner squeezeboxserver:nogroup, Permissions: 777

If you want to set up equalization, this can be done either using the browser interface or via iPeng on an iPad or Orange Squeeze, Squeeze Commander.

Let us know how you get on.

[firedog]

almost there

Thanks for your help. I made progress.
I have convolution/filter files I made in Audiolense. They supposedly are 32 bit float, and are wav files.
I loaded them into my Touch, but can't get playback.
Here's the log output showing the error, I'd appreciate it if one of you can tell me what this means and how to fix it.

Okay, above I wasn't getting playback but now I am. But I still don't think the RC is working properly. Question: I have 6 correction filters, one for each common sample rate: 44.1, 48, 88.2, 96, 176.4 and 192. In the "EXTRA" settings of the Touch, it seems only to allow me to use one filter. Does, Ignuz not know how to interpolate the filters for each sample rate? How do I do correction for playback files with different sample rates if I can only choose one of the filters?

You say you have loaded the FIR files into your touch.

Are you running LMS on your Touch, rather than on a separate PC, etc? If so you will not be able use the Inguz plugin - the Touch just doesn't have the processing power.

No. Sorry for not being clear. I've got a pretty powerful Windows server with LMS running on it. When I said I loaded the files onto the Touch, I meant I went into Extras>EQ>Room Correction and picked one of the correction filters that show up there - the ones loaded into C:\ProgramData\InguzEQ\Impulses on my server.

Thanks

Okay, above I wasn't getting playback but now I am. But I still don't think the RC is working properly.

Does, Ignuz not know how to interpolate the filters for each sample rate? How do I do correction for playback files with different sample rates if I can only choose one of the filters?

You can only choose one filter to be active at any time.

If the FIR filter has the same sampling rate as the file being played it will be used.

If the filter has a different sampling rate then Inguz will attempt to resample the filter to the sampling rate of the file and save the resampled filter in the folder C:\ProgramData\InguzEQ\Temp\

If it can't resample the filter then Inguz can't process the music file, but it should still play.

Here's the log:

That, the first bit of the "second" log, looks right

In the following section you are playing a 44.1kHz file, still using the 96kHz filter.
Inguz first checks whether it has previously created a resampled file, but there is no resampled file present.
So it attempts to resample the filter file using sox.

BUT for some strange reason it hasn't picked up on the sox path

20200128191523: b8:27:eb:3a:b6:bf Trying sox "C:\ProgramData\InguzEQ\Temp\RE00B9A7FE0A.wav" "C:\ProgramData\InguzEQ\Temp\44100_0038F87BF0_Impu lses_T-flat F-Default M-hogtalare 27012096.wav" rate -v -I 44100

Should be

20200128191523: b8:27:eb:3a:b6:bf Trying "C:\Program Files (x86)\Squeezebox\server\Bin\MSWin32-x86-multi-thread\sox.exe" "C:\ProgramData\InguzEQ\Temp\RE00B9A7FE0A.wav" "C:\ProgramData\InguzEQ\Temp\44100_0038F87BF0_Impu lses_T-flat F-Default M-hogtalare 27012096.wav" rate -v -I 44100

I'm not sure why that has happened but Inguz needs LMS to be restarted a few times for it to be fully operational.

So I suggest you:

Stop LMS
Delete the contents of C:\ProgramData\InguzEQ\Temp\
Restart the Touch
Restart LMS

Let me know what happens

(I'll come back to you on Internet Explorer - it might be that Silverlight isn't enabled in its settings.)

[JohnB]

firedog,

I've just looked at the code for InguzDSP. It looks as though, on your PC, it couldn't fine sox.exe in the location it was expecting to find it and so just used "sox".

In my W10 system sox.exe is in folder: "C:\Program Files (x86)\Squeezebox\server\Bin\MSWin32-x86-multi-thread"

Can you check whether sox.exe is there on your Windows machine.

[firedog]

Thanks again. My Sox.exe is in the same place as yours. So the question is, why is Inguz looking for it in the wrong place? And how do I "fix" that?
I also followed your other advice about deleting files and restsrting LMS and the Touch. Same results as you saw above. Whenever the samplerates of thr filter and the playback file don't match, Sox isn't found.
