Sorry this is a long post. I've combined the instructions for Windows installation into this one post.
*MANUAL INSTALLATION FOR WINDOWS* *INSTALLING THE PLUGIN* The plugin is the user interface: it lets you control filter functions from the Squeezebox remote control. To install: Download the plugin from: http://inguzaudio.com/EQ/download.php Unzip in the Logitech Media Servers Plugins directory. You should end up with a folder C:\Program Files (x86)\Squeezebox\server\Plugins\InguzEQ\ containing the plugin file Plugin.pm and a few other supporting files. Stop and restart the Logitech Media Server. Open the Logitech Media Server web interface, select Settings -> Plugins. Verify that the EQ plugin is checked. On a Duet: using the remote control, select the EQ menu (under Extras) or on a Touch use the Touch screen. You will see a message indicating that the server must be restarted. Stop and restart the Logitech Media Server a second time. *INSTALLING THE FILTER PROCESSOR* The filter processor is the engine: it processes audio files as they are played, and sends the processed audio to your Squeezebox or Transporter. To install the processor: Download the filter processor from: http://inguzaudio.com/DSP/download.php Unzip in the Logitech Media Server C:\Program Files (x86)\Squeezebox\server\Bin\MSWin32-x86-multi-thread\ folder. Youll see a few new files, including InguzDSP.exe, in the folder. *INSTALLING UPDATED PLUGIN.PM, INDEX.HTML* The original plugin.pm is not compatible with Perl 5.22 or higher so I amended the file. Download an updated Plugin.pm from the bottom of this folder: https://forums.slimdevices.com/showthread.php?77084-RC-(Inguz-etc-)&p=903072&viewfull=1#post903072 On Windows 7 64 bit, copy the Plugin.pm file to folder: C:\Program Files (x86)\Squeezebox\server\Plugins\InguzEQ\ bobertuk did a fix in* index.html* for the missing text 'Save Preset' in the button in the web interface when using Internet Explorer. Download an updated index.html from the bottom of this post: https://forums.slimdevices.com/showthread.php?77084-RC-(Inguz-etc-)&p=903072&viewfull=1#post903072 On Windows 7 64 bit, copy the new index.html to folder: "C:\Program Files (x86)\Squeezebox\server\Plugins\InguzEQ\HTML\EN\plugins\InguzEQ\ *GETTING STARTED* STARTING THE PLUGIN LMS may not recognize the plugin immediately when its installed. Then, when the plugin is first used, it needs to write some configuration information. The first time: Restart LMS. From the LMS web interface, select Server Settings -> Plugins. Verify that the EQ plugin is checked. Verify that the Plugins menu or the EQ plugin are active on the player. If you have a Duet: Using the remote control, select the EQ menu (under Extras). If you have a Touch: use the Touch screen. You will see a message indicating that SqueezeCenter must be restarted. Restart LMS a second time. Check the LMS/Settings/Advanced/File Types that the InguzDSP options are enabled. RUNNING Now the plugin and filter processor are installed, you should be able to play music. From the Duet remote control or Touch screen, etc, you can configure the plugin and change equalization settings. For room correction, you need to create and install room correction filters. After playing the first track, check that theres a file Log.txt in the application data folder (C:\ProgramData\InguzEQ\). This is the filter processors log file, and you should read it occasionally to check that the filter processor is working properly. More detail about the log file can be found below. LOG FILE When the filter processor runs, it writes information into a file log.txt, which you can find in the InguzEQ folder. On Windows 7 64bit, this is in C:\ProgramData\InguzEQ\. You can read this log file with a text editor. No updates in the log? If you play music but there are no updates in the log file, first check that the LMS file types are selected properly (see the installation instructions for details). A TYPICAL LOG For each track played, you should see a series of lines in the log, like this: 20070104235906: InguzDSP (version 0.9.12) -wav -d 24 -id 00:04:20:10:01:ae -r 44100 20070104235906: 00:04:20:10:01:ae This evaluation version will expire 6/1/2007 12:00:00 AM 20070104235906: 00:04:20:10:01:ae Gain -16 dB 20070104235906: 00:04:20:10:01:ae Impulse Impulses\Normal.wav, matrix MatrixImpulses\Space.wav 20070104235906: 00:04:20:10:01:ae EQ00323806D3 20070104235907: 00:04:20:10:01:ae 16/44100 PCM => 24/44100 PCM TRIANGULAR, gain -16 dB 20070104235921: 00:04:20:10:01:ae 232:The pipe is being closed 20070104235921: 00:04:20:10:01:ae 1802240 samples, 14609.375 ms, 2.7379679144385 * realtime, peak -6.6932641448126 dBfs The number at the start of each line is a timestamp: in this case, 2007-01-04 (January 4th), 23:59:06. The 00:04:20:10:01:ae which follows the timestamp is the ID of your Squeezebox (its MAC address). In normal use, youll also occasionally see series of log lines such as this: 20070105000200: 00:04:20:10:01:ae Configuration changed 20070105000200: 00:04:20:10:01:ae Configuration changed 20070105000200: 00:04:20:10:01:ae Impulse Impulses\Normal.wav, matrix MatrixImpulses\Space.wav 20070105000200: 00:04:20:10:01:ae EQ005215B387 A sequence like this is logged each time you change the equalizer settings using the remote control. Clipping! Clipping is when the digital signal gets too large: the signals too loud, and the only way for the filter processor to handle these is to clip off the peaks (and then reduce the volume a little). If clipping happens, you will see messages in the log such as this: 20070108225053: 00:04:20:10:01:ae CLIPPING+ 20070108225058: 00:04:20:10:01:ae CLIPPING- It may be OK to see one or two clipping messages, but if you see lots more than a couple in an hours listening, for example then youll need to decrease the filter processors gain control. Too quiet? Depending on your setup, you might find you have the opposite problem: the signal is way too quiet. This doesnt produce log messages like clipping does. Instead: take a look at the last line from the log above: 20070104235921: 00:04:20:10:01:ae 1802240 samples, 14609.375 ms, 2.7379679144385 * realtime, peak -6.6932641448126 dBfs The peak value here means: during this track, the loudest signal was about 6.7 decibels below full-scale. (These numbers should always be negative. Zero decibels is as loud as the signal could possibly get; anything more is clipping). Watch this peak value as you play a mixture of different types of music. If the peak value never goes above, say, -9dBfs, then you have lots of room to increase the processors gain control.
