Re: [SlimDevices: Audiophiles] RC (Inguz etc.)
I don't want to put anyone off and I am sorry if this is overkill or not appropriate for the forum, but I thought it might be useful to post an example of the DRC correction filter creation process using Acourate. These are a few screen shots of one of the versions I did. It is for my main speakers, without sub. 1. The measured response. (That "combing" isn't at all unusual) 23389 2. Amplitude preparation - i.e. a smoothing of the measured response. There is a trade off - the more accurately this follows the measured response the more restricted and narrow the listening position is. Acourate allows you to adjust how accurately it follows the measured response (Audiolense has 3 settings which do the same), but this is Acourate's recommended setting - a best compromise. 23390 3. Target prepartion. This shows the target curve (in black) after I prepared it, against the curves used to calculate the DRC filters. 23391 4. Filter generation. This is Acourate's simulation of the DRC result with the filters it has generated for that target and the amplitude file. It includes the target curve. 23392 +---+ |Filename: 4-simulated result 800.jpg | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=23392| +---+ Touch, Meridian G92, Meridian G55, PMC OB1i speakers, HP Proliant Microserver/Ubuntu, PC/Windows 7, iPad 4, iPeng, Squeezepad.

Re: [SlimDevices: Audiophiles] RC (Inguz etc.)
Bob, As you know, the GUI has been a problem for many years - one the rare occasions I need the GUI I use IE. As far as DRC is concerned, the correction impulse files, and how they are created, are critical. I might be wrong but I don't think REW creates these. There was a basic method that was described in the original Inguz instructions. I seem to remember that there was a Youtube video which someone did to demonstrate how to do this, so it might be worth looking for this. I did have a go using it but didn't get very far. For more control over the filter creation process there are two software packages that people have used (see below). They are expensive but they do give good results. The basic procedure is: - measure the room response (using a microphone and soundcard) - display the room response and create a target response - run the software to create the correction filters to use with Inguz - copy the correction filter wave files to the Inguz Impulses directory. In practice it is an iterative process - and people try different targets in order to get a final response which they feel is the most pleasing. Why not use a flat straight target? Well that doesn't necessarily work best for many people. One thing worth mentioning: sometimes a room will have a deep null (or near null) in the bass region - no DRC (or amplifier) can correct that. It will be caused by the room modes and the only solution is to move the listening position. I found that one incidental benefit of setting up DRC is that I had to start to scanning the room frequency response and that made me think about loudspeaker and listening positions. As a result I moved things around to make the frequency response smoother even before DRC. These are the software packages that were available a few years ago when I started looking at DRC. I use Acourate, Phil Leigh (who posted a lot on Inguz) used Audiolense. I have no idea to what extent they are currently being developed and there might be other options these days: AUDIOLENSE This comes in two versions: _Audiolense_2.0_ (165 Euro) - a more basic version which is very easy to use but has limited options. However this will be fine for most people with a stereo system. _Audiolense_XO_ (390 Euro) - a more advanced version with cross over design, etc, etc. Probably overkill. There is a trial version which enables you to create a corrected wave file that lasts 90 seconds, but you can't save your work. One advantage of Audiolense is that the room measurement is done within the main package, so you can see the result immediately. ACOURATE This costs 340 Euro. It is chock full of options which the non-expert will find totally confusing. However, once you get over the initial feeling of panic and follow the basic instructions it isn't so frightening. There isn't a trial version, but you can use download the measurement program for free and use that to measure the room response, send the impulse files to the developer together with a music clip of a few minutes and he will send you back a corrected version of the music clip. In either case - I'm not sure of the usefulness of the test files. They give some indication but, as I said, getting to a good result depends on trying various targets.

Re: [SlimDevices: Audiophiles] RC (Inguz etc.)
John & Wirrunna Using Johns commented instructions I have Inguz working on an Intel-NUC which seems to have more than enough CPU power to run Inguz. I'm using Ubuntu 16.04 LTS. John, I just followed your instructions to the letter, apart from having to modify permissions a little. The biggest problem was getting the EQ GUI working - initially I tried installing a silverlight lookalike for Linux called 'pipelight' in the hope of being able to get the GUI running direct in a web browser on Ubuntu. No luck, just couldn't get it to run in either Chrome or Firefox. So I downloaded silverlight for Mac and after activating it in Safari it works fine - well, the GUI anyway - connecting through Safari to the NUC on port 9000 is all that's needed. The adjusters (up and down buttons) for EQ work but most of the other adjusters, e.g. 'Quietness', do nothing. I seem to remember reading about this problem years ago and if I recall correctly, it was something to do with the version of silverlight being used, an earlier version being required. Could get it functioning on Windows 10 with IE and Safari (but not Edge) but still the same issue with the adjuster buttons. I seem to recall there was a way of getting those buttons to work but for the life of me I can't remember how. I get sound out of the speakers and changes to EQ changes the sound produced so in principle it's working. Except I don't have a clue how to get room correction up and running. I have REW and a USB calibrated microphone but don't know what file types to export from REW or where to put them in Inguz. I know that information was on the Inguz website but it's no longer accessible. There's a whole raft of threads on this forum about Inguz and I'm sure the information could be sifted out but I'd be grateful for any help here.

The directories and paths you quote are those applicable on Ubuntu (Debian). Actually, as far as I understand it, -/usr/share/squeezeboxserver/Plugins/InguzEQ/- is a soft link to -/var/lib/squeezeboxserver/Plugins/InguzEQ-. You say you are running Fedora. I know very little about it but, from what I can gather, there are similarities between Fedora and Redhat. The Inguz installation guide for Redhat differs from the Debian installation in that it uses different paths to the installation directories. So you might want to look at the Redhat installation instructions. In the Plugin.zip that you posted in #393 there are the original Inguz instructions for Redhat in file "inguz audio ยป Installation on Red Hat linux.htm" (when Plugin.zip is unzipped the instructions are in the Plugin/InguzEQ folder). A few points: - In the instructions, you will need to change "slimserver" to "squeezeboxserver" where it occurs in the paths, e.g. "-/usr/local/slimserver/Plugins/InguzEQ-" becomes "-/usr/local/squeezeboxserver/Plugins/InguzEQ-". - The instructions refer to SlimServer - this, of course, is now LMS. - Inguz requires mono to provide Windows Net 2 support. When I installed Inguz on Ubuntu I was very green and had problems with mono. In the end I installed mono-complete (sudo apt-get install mono-complete) which is probably a gross over-kill - there is almost certainly a more elegant solution. - The instructions mention restarting "SlimServer" (i.e. LMS). In Ubuntu the terminal command for this is: -sudo /etc/init.d/logitechmediaserver restart- but I'm not sure whether it is the same in Fedora. I rebooted my Touch and restarted LMS a few times.

Re: [SlimDevices: Audiophiles] RC (Inguz etc.)
This is a copy of the InguzEQ plugin.pm that I edited. Details of the edit are documented in the file, just after the original version history, though, of course, the line number of the edit will now have changed because of the lines I added to describe what I did. There are absolutely no guarantees that my edit is correct or successful, but it doesn't throw up any errors on my Ubuntu system and it seems to work OK. I've had a quick look at the InguzDSP.zip file that you uploaded. The installation directories shown in setup files are different from those used in the Debian (or Ubuntu) installation - possibly because you are using Fedora(?). The Inguz plugin.pm in your zip file seems to be the last one that Hugh Pyle issued and is the one that I have successfully used in Ubuntu 14.04 (which uses Perl 5.18) and then edited to amend the deprecated code. +---+ |Filename: Plugin.zip | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=23387| +---+ Touch, Meridian G92, Meridian G55, PMC OB1i speakers, HP Proliant Microserver/Ubuntu, PC/Windows 7, iPad 4, iPeng, Squeezepad.
