[Beta Announce] Revised Inguz DSP plugin

[Wiredcharlie]

Thanks - that was it

[foxesden]

I have been setting up a new installation. Where do I put my impulse (wav) file in Ubuntu? The old setup was /usr/share/InguzEQ/MatrixImpulses - but the filter does not show up in the Room Correction dropdown.

Thanks foxesden - good work!

Tony

on my Ubuntu virtual box environment it is

/var/lib/squeezeboxserver/prefs/InguzEQ/Impulses

NB should be under the squeezeboxserver/prefs as this is the recommended location

I have refreshed the key settings in the Plugin repository and tried a clean install on picoreplayer. via the plugin menu. NB You need to shut down the players and restart them after install , then use the EQ setup screen (accessed on the Extras Menu). I then restart LMS for good measure) - as there is no easy to access restart button I just install/uninstall a plugin I don't use like Tidal as it is quite quick to do.

Once this is done you can amend the file settings as above.

Hi - can you confirm what steps you have taken to get this installed and working?

I am working on a replacement for Squeeze EQ so I don't have it installed at the moment, and just re-installed it now, via the plugins menu.

I had an old custom.conf file that I needed to clean (NB this should not be a problem for most people, unless you uninstall and re-install a lot)

The problem that most people will face is with file types and the conversion path.

For example Spotify has it's own file type and typically people playing it will need the source converted to flac, ogg, pcm etc. in order to play it. There are some conventions that the developers established, which basically say prefer the shortest route to the desired target file type, over a longer route and some fuzzy stuff if the file type is less preferable vs a longer route.

Unfortunately the above means that adding EQ into the mix lengthens the audio path and by default the setup gets ignored. Hence to make it work we need to play about with file types, as this would be difficult to add into the build without breaking loads of stuff.

I have just re-enable Spotty via Inguz

spt	flc	[DISABLED]	*	*
	flc	[spotty.exe|flac|sox|InguzDSP]	*	d0:50:99:85:19:e9
	mp3	[DISABLED]	*	*
	ogg	[DISABLED]	*	*
	pcm	[DISABLED]	*	*

On the file type interface (Settings->Advanced->File Types)
It looks like this



The top flac entry converts directly from spotty to flac, which is the preferred route, so we need to disable it - second is a duplicate. The MP3 route will be selected in preference to our DSP route as it is shorter as will the PCM so we need to disable them. Ogg Vorbis has been removed at some point, but we would want to disable it anyway. This leaves us with a 2 step conversion once to from Spotty to sox and another from Inguz to flac.

I am sorry it is so complex, it certainly confuses me!

Sorry for the late response. I read through the thread and found your repo and installed that way. What do you mean you enabled Spotty via Inguz? Is that different than just enabling it through the plugin menu? I have more entries in file types then your pic shows. I assume that is becuase I have a lot of different players? If I disable ogg vorbis nothing plays. If I enable PCM music will play. Seems there is something wrong with playing flac. I can see when ogg is disablled it is trying to convert to flac but the music looks like it tries to start but after 5 secobds goes back to zero and nothing plays. See this in the log Slim::Player::Song:Open (424) Error: Couldn't create command line for spt playback for [spotify://track:6pRPoKyrZ2VNlgpvU6wwNB]

i tried only activating one player and that shorten the list of options by a lot but still same result. Music won't play

[foxesden]

trying to get this working and I see this in the log. I tried chaning the file types. When I disable Ogg Vorbis spotty doesn't work. I can see that its trying to convert to flac but it won't play. When it's enabled the music plays

What do you want to achieve by enabling the settings? In order to use Inguz the plugin tries to bypass the default settings, so by re-enabling you may make it less likely to work. Bit more of an explanation below.

The drop downs allow you to select the options that you want, I think you knew that much. The tricky bit is getting those settings right as it is a bit of a dark art. You need to know what formats your player can accept and then set the mappings accordingly, I tried to get the defaults correct with the Inguz plugin, but it doesn't work in all cases.
What I do is I download the C3PO plugin and then view the settings in C3P0 vs the player in question (NB don't enable C3PO for the player if you want to use Inguz on it as both plugins will compete to produce a config and C3P0 will win). What you can do is view the settings just played, this allows you to change the file types play a WMAL file and see the effect on the settings. It's a bit of a pain, but you will get there.

I don't really use WMA Lossless as a source myself. But I think you want something like this


WMA Lossless
FLAC (F, R) wmadec/flac
FLAC (F, R) wmadec/InguzDSP
MP3 (F, R) Disabled
PCM (F, R) wmadec
WMA Lossless (F, I) Disabled

The file types are disabled from the Squeezebox Advanced Settings screen. How do I re-enable it?
Thanks again for your help.

[foxesden]

Hi,
I thought I played all file types using Inguz but its the first time i actually played WMAL (WMA Lossless). As the file start playing, it gets jumbled up with sound suddenly burst out loud and clipped.
Noticed the mappings in File Types for WMAL are all disabled (see below). Anything I can do to re-enable it to use Inguz properly?
FYI all other files types work fine with Inguz effect.
Thanks

Regarding Separate files - currently you have to merge to Stereo as Apesbrain suggests.

I get where you are coming from with the preset vs filename. I think, I have this fixed in the new DSP plugin that I am working on. NB I have fixed it and tested but I can't be 100% sure it works in all cases.

[Zombie]

This might be a very small thing, but anyway
When I choose the Room Correction file it sticks between restarts etc. and it is possible to choose None.
But with Load a preset: the chosen preset disappears even if I just move elsewhere in LMS and come back. It changes to None, but the setting is retained regardless of LMS being restarted etc. Is it possible to keep and show the name of the current setting? Not a big deal, but a little pimple in the backside nevertheless.

[Apesbrain]

Is it possible to use convolution files for L and R separately in InguzEQ in LMS?

Interesting question. If you have separate mono impulse WAVs for L and R, try combining them in a stereo WAV. Audacity should allow you to do this, then export as a stereo 24/48 WAV.

I don't know if this will work, but easy enough to try. Just watch your volume until you know what it does.
