Could you give more information please? I don't understand how to use it. I'm not even sure about what it is supposed to do.

This plugin extracts bass from the source signal using low-pass filter and send it to the separate channel (LFE).
It can be useful if you have 2.1 or 5.1 audio system.
Standard realization of this task used IIR or analog filters, which fast, but produce phase shifting.
The high-quality filtering needs linear-phase characteristic, which can be achieved only by using digital FIR filter.
This plugin also allows to use various type of filters, not only Linkwitz-Riley, which often using for split frequences. The filter slopes builds using piecewise functions in logarithmic scale. If you need a Linkwitz-Riley filter, select "HyperTangent" - their slopes are identical.

First install.

Find the problem.  The plugin conflicts with Winamp Bridge (which I seldomly use) resulting in crashes.
Title: Re: Linear Phase Subwoofer
Post by: Chibisteven on 09 May, 2016, 10:48:05 PM
Conflict with Matrix Mixer (foo_dsp_mm) also found (this one I use a lot) and if in the DSP Chain with your Subwoofer plugin and you seek a song using the progress bar it results in a crash.

Post by: E.Sokol on 10 May, 2016, 02:08:46 AM
Chibisteven, thanks for it. I try to reproduce this crash first.
According to your failure report, crash raised when logarithm function calculated.
Even if the argument is illegal,  foobar not crashed on my pc.
 I can try to use another math lib.

Chibisteven, on my Win8.1 with Foobar 1.3.10 any combination of Subwoofer / Matrix Mixer / Winamp DSP Bridge works well, no any conflict found.
May be problem plugin is not mine.
Did you can send me a full content of your "foobar2000" folder, including "C:\Users\...\AppData\Roaming\foobar2000"?

Please try this plugin with different parameters and feedback your experiences. I used my own formula to generate the frequency response, and I'm interested in opinion from other people.

Features:
- fast fir processing
- adjustable slope with linear phase
- mono, stereo, triple and quadro input support
- double bass array output support

Hi, Thanks so much for your work,  I was looking for a plugin like this, I had to disable Resampler(PPHS) to avoid foobar  crashes when changing songs.
Title: Re: Linear Phase Subwoofer
Post by: xsdaver on 07 August, 2016, 06:02:01 PM
I just tried this today, it worked great.  I'm using the SoX resampler before it with no issues.  One feature that I'd like to see is the option not to high pass the main channels.  I typically run my main speakers full range and low pass the subs.

Thanks for a great component!
Title: Re: Linear Phase Subwoofer
Post by: xsdaver on 08 August, 2016, 08:13:23 AM
I have a couple more feature requests that would really make this easy to use and set up:


OK, more than a couple.  The first two in particular would allow you to dial in the system from your listening chair as well as providing greater flexibility for sub placement.

Thanks for any consideration you may give to these.

Post by: xsdaver on 08 August, 2016, 07:17:47 PM
Someone pointed out to me on another thread that you can save DSP chains so the request for the plugin to remember settings goes away.  One down!

I've been using this component for a little over a week on two different PCs and I have to say that I'm getting the best sub/main integration I've ever had.  Sound quality seems unchanged, no glitches or issues of any kind.

I tried using channel mixer component to adjust the level and delay of the LFE channel but Foobar crashed as soon as I tried to view the DSP window.  Reporting the incident gave the message that channel mixer was a known buggy component so it got promptly removed.
Title: Re: Linear Phase Subwoofer
Post by: E.Sokol on 15 August, 2016, 01:02:08 PM
xsdaver, thanks for your feedback! I will add the ability for LFE delay and disable high-pass filtering a bit later.
I think, the LFE digital level control is not good idea, because for prevent clipping it can be only quiet.
Title: Re: Linear Phase Subwoofer
Post by: xsdaver on 15 August, 2016, 01:17:19 PM
Thanks for the reply.  The ability to adjust the LFE level relative to the main channels is pretty important for me.  In my case, I'm driving three subwoofers.  While I can adjust the level of each, each is independent so I will either have to match them every time I adjust the overall LFE level or live with them at different levels.  In the end, this may not be all that big a deal if they are close, but I'd prefer to have them as close as possible.  If I can go through the exercise of matching the level of the three together once and then adjust the overall level through the software it works out much better, at least for me.

If clipping is a concern, perhaps the ability to attenuate both the LFE and main channel is the best way to go.  Thoughts?

I was getting set up to balance the subs and mains.  I had generated a pink noise track in Audacity so I can play it through FooBar and have it processed like a music track.  Only FooBar with this subwoofer component separates the bass so I can send the bass to LFE outputs.  If this component is loaded in the DSP stack only bass comes out.  If I remove it, the mains work, but of course no bass.  It is the only active DSP.  I'm baffled.  Any suggestions?

Sorry, but i can't understand what your problem.

Post by: xsdaver on 28 August, 2016, 12:45:34 PM
If I play a track that is pink noise, nothing comes out of left and right, only the LFE channel has the noise.  The LFE channel noise is filtered so it is only the low frequencies and seems to be getting through the plug-in correctly.  There is no sound coming out of the main left and right speakers.  With music it works great, with noise nothing out of left and right.  If I take the subwoofer plug-in out of the DSP stack the left and right work, but of course no subwoofer.

You can download the noise file I used here;
http://www.xsxpress.net/files/pinknoise.zip (http://www.xsxpress.net/files/pinknoise.zip)

or create one with Audacity, or I'm sure there are plenty on the web if you don't happen to have one.
Title: Re: Linear Phase Subwoofer
Post by: E.Sokol on 28 August, 2016, 02:13:50 PM
Your file "Pink Noise 96kHz -0_8.flac" is mono. On mono files, plugin produce two-channels output - one center and one subwoofer. You have not sound at left and right speakers because it sounds at center speaker. To solve this, convert input signal to stereo before subwoofer plugin.
Title: Re: Linear Phase Subwoofer
Post by: xsdaver on 28 August, 2016, 02:29:18 PM
I figured if I did not have the create center channel box checked it would not create a center channel.  Apparently it does?  Now that I know what it is doing I can route the center channel to left and right to get the output I'm looking for.

Hi, I am using foobar v1.3.9 because later versions does not load most of the VST plugins correctly.
When I'm using the subwoofer component(v1.2.0) along with any of the DSP components (Dolby headphone, DTS Neural, or Channel mixer) foobar crashes when I seek with the playback position.

I am not able to attach failure log file here! I will give the details in next post

hi, I want to compliment this plugin, really interesting the idea of implementing a linear phase eq ... no professional dsp does it!
i agree with the other request from xsdaver (delay and level for sub) but i wolud to ask you another thing:
I do not know what interfaces you use to have a separate LFE channel, but with professional audio device there is a need to select the physical output of the sound card to have another channel for the subwoofer, otherwise from my L / R outputs I only get a high pass filter ...
So, could you integrate a system to select the interface output to use for the LFE channel?

I personally use a custom ASIO channel mapping for my DAC. If you're DAC has an ASIO driver and really offers more than one set of outputs, you easily have 2.1 outs. I route LFE to 3/4 for my UR44, and of course 1/2 are L/R to my monitors. The ASIO plugin for foobar will then let you set up the actual mapping.

I also would also  like delay support. Up until today I had been using channel mixer as a subwoofer DSP, setting it to 6 channels and only leaving L/R and LFE checked. It was a bit finicky at times, especially if trying to adjust it while audio is playing....  Anyways, switching back and forth between my (many times perfected) channel mixer settings and your plugin which I set a slope up rather quickly, the response is obviously much better with yours.

Phase is unfortunately way to big for me though, so I'll still stick with channel mixer in until you hopefully add delay.

So I actually want to request two things, first is obviously the delay. The second however, would be individual control of the slopes for both LFE and L/R. Trying to pair my monitors with my sub, it sounds much better if I let them rolloff naturally with no crossover and only set sub. I still want to have a crossover on them though, but really just a subsonic, so rolloff around 35-40hz.

hi, I want to compliment this plugin
thanks

i agree with the other request from xsdaver (delay and level for sub)
Please try new version (1.3) (https://foobar2000.org/components/view/foo_dsp_subwoofer)

but i wolud to ask you another thing:
I do not know what interfaces you use to have a separate LFE channel, but with professional audio device there is a need to select the physical output of the sound card to have another channel for the subwoofer, otherwise from my L / R outputs I only get a high pass filter ...
So, could you integrate a system to select the interface output to use for the LFE channel?
I not plan to do this yet, for some reasons. But you can use Matrix Mixer (http://skipyrich.com/wiki/Foobar2000:Matrix_Mixer) for this purpose.

New update is great. Definitely the best plugin for subwoofer management. Delay is working fantastic.

All I get when I start foobar is:

Failed to load DLL: foo_dsp_subwoofer.dll
Reason: This component is missing a required dependency, or was made for different version of foobar2000.

I have foobar2000 1.3.16 on Win10 Pro 64bit.

Make sure that you use official version of foobar. Try to copy  foo_dsp_subwoofer.dll to \foobar2000\components\ folder manually.

5.1 soundcard have a additional stereo out with center/LFE channels. Subwoofer outputs at LFE channel.
Also check your soundcard mixer - it must be in surround mode, not stereo.

Ok thanks, that's the info i've been missing. Any ideas if this is possible with a secondary soundcard instead of a 5.1 one?

Not possible. No way to synchronize audio from different soundcards.

Ok thanks for all your answers !

Last question, a bit out of context but whil I have experts on the hand... Do you know if it's possible to split the sound from the computer tu 2 different cards: one program on one soundcard and another on on anoher soundcard (I don't need them to be synchronized)

Some programs have option for choice output device. If this option not present, they used default device, which selected at Windows Mixer. You can try change default device before each program launch.
