Thank you, I switched from WMP11 pretty much just for this.

Edit: Unfortunately, for whatever reason, songs seem to sound thick and "dirty" with the plugin enabled. Particularly the vocals and the subwoofer. I hope I can tweak it, because it's a really awesome plugin (i.e., it's no so bad that I will not use it). I am having a tough time deciding if I want to go back to WMP11.

It seems to mostly be my levels, I've been tweaking it, it sounds a lot better. Good work, thanks again =)

What setting should I use with channel mixer on my logitech Z-5400 system?

Now I'm using 6 channel, I know some settings are subjective, but my doubts are about how low ranges will be redirected.
In particular the "Add low freqs" under upmix, and all the subwoofer tab.
My current setting are "add low freqs" unchecked, use subwoofer enabled and bass redirection disabled.
The sound is pretty good, but I'm afraid I'm stressing too much satellites with low freqs...
Anyone using a logitech 5.1 system that can help me with this plugin?

nebrion, the setting "add low freqs" is for full-range-systems only! Never use it with systems with subwoofer.

^^ disabled...and other settings under subwoofer tab?


I suppose "use subwoofer" should be checked, what about bass redirection?

In your case, those settings are sending full signals to both the subwoofer and the sats.  Since you are generating a full 6-channel source, this should be sent unmolested by any soundcard bass-redirection, but your Logitech system has it's own bass crossover filter hardwired.  This will do a high freq pass on your sats, and send them to the sub.  I do not know if it compensates for the attenuation.  (I doubt it)

I would enable bass redirection at 120 or 150Hz (depending what your Logitech uses internally) and set it to "Keep subwoofer intact".  This will prevent over-boosting the sub and sats.

So you think if I don't check bass redirection will be the logitech system to apply the internal crossover filter?
If I check bass redirection to leave sub intact and redirect at 120-150 Hz it seems I get less bass pumping compared to when the box is unchecked.
What do you suggest? leave bass redirection managed by internal crossovers, or let channel mixer do that?
Now I search for my satellites specs to see which range they support...(I have to search in internet, there's nothing written on the manual)
choosing to filter at 120Hz sound is very "thin", empty

CRASH REPORT:

When using channelmixer together with ATSurround DSP component (for headphone listening) I switched from 5 channel output to 4 channel output and the foobar2000 application crashed.

Here is the crash log/dump from foobar2000:

http://pastebin.ca/781479

OS: Windows XP x64 edition (sp2)

EDIT: Also tried it only using channelmixer (no ATSurround), and it crashed then too.

I'm playing DTS audio, so the foo_dts component might be buggy too.

At least look into it. You should be able to switch stuff on the fly without having it break down on you.


Also a feature request: Virtual surround (so I don't need ATSurround DSP at all). There should be some code for this in the open-source world. Head related transfer function or something.

I can't reproduce this crash, the only thing happened when I add ATSurround to the DSP chain is dramatically increased CPU usage.
Please describe all steps to reproduce this crash, your settings for both ATSurround and Channel Mixer, etc...

sorry if I'm not being too clear about things. I can rephrase my post if you want to.

I'm also aware that this bug may very well be impossible to reproduce on any other PC than mine.
But the fact stands: foobar2000 only crashes when I switch output channels in your component.

I have stopped using ATSurround as it only helps when listening to actual surround music (which I don't do that often anyways). It also applies too much echo.
I have also stopped using channel mixer as it's only made for those who actually have a surround speaker setup. I only listen with a stereo speaker setup and headphones.
What I wanted was a virtual surround DSP effect that works just as Dolby Virtual Surround in Cyberlink PowerDVD for use when I listen to surround music.
so If you can't find any more bugs nor reproduce my crash, it's not that big of a deal.

I had try to test some combinations of plugins in the DSP chain, try to switch output channels count, but nothing happened. Then I wrote to you, that I need more details - how many DSP's in the chain, its order, its settings and your every single movement by mouse or keyboard.
If I ask you for something, then I really need it.

saivert, what output plugin were you using? Perhaps the switch in number of channels triggered some kind of audio driver bug? XP64 isn't known for having reliable drivers.

Also, foo_converter is the first component listed in the stack dump. Were you converting a file at the same time? With DSP?

Finally, there are several sketchy third-party components listed in your error log. Do the errors still occur when you remove third-party components that aren't foo_channel_mixer?

I've spent significant amounts of time playing with foo_channel_mixer and have had no problems with it.

After some testing I have found the bug in "delays" code (BTW, saivert, any word from you about the delays?).

Bugfix release (0.9.6.3):
* fix the memory corruption while using delays with 4,5 or 6 channel output
+ enable buffer overflow detection

turn off any crossover filtering in the driver apps, and in foo_channel_mixer.  You want to use large speaker mode on all 5 sats, and the internal crossover circuit in the Logitechs will do the filtering.  If you use software crossovers, which roll-off freqs around the xover point, the hardware crossover will only make it worse, and maybe even introduce holes in the frequency spectrum. (this is bad)

Hey, is there any way this can do 7.1? I'm missing the utilization of two channels here!

I only get sound out of my front 2 speakers. The rear two, no sound, even when I select channel to 4.

btw. will you gave us some betas to test? 

So, the new year has come 
This is the first beta, that has a fast enough implementation: http://skipyrich.com/store/foo_dsp_mm.7z
No filtering, no delays, no bass redirect and an ugly interface, so don't be scared - you are warned

Awesome plugin. There are two features that I would like to see in a final version. Both have to do with normalizing a matrix so that it allows peaks of 1.0 while being clipping-proof. A checkbox to normalize a matrix would therefore be nice. Checking the checkbox would change the basic matrix to a normalized matrix. A normalized matrix has a maximum possible peak of 1.0 per channel.

Basic matrix:
Code: [Select]
   |FL    FR    FC    LFE   BL    BR
---+-----------------------------------
FL |1           0.707 0     1
FR |      1     0.707 0           1

Normalized matrix:
Code: [Select]
   |FL    FR    FC    LFE   BL    BR
---+-----------------------------------
FL |0.369       0.261 0     0.369
FR |      0.369 0.261 0           0.369

The second feature would be a normalization that takes into account which input channels are actually used to calculate the normalization factor. The 5.1 to 2.0 matrix from above is perfectly suited to handle stereo signals but a normalization would not be necessary and would in fact lead to a signal with very low volume. So the plugin should have a second checkbox that enables an automatic normalization factor calculation depending on the actual input channel usage.

The plugin does both types of a matrix normalization by default. There are no checkboxes to turn it off, and I can't see why to add it

Speaking about normalization and downmixing...

I'm using this plug in F2k for stereo downmixing my 5.1 material and it's the only one!!!! Thank you.

But...why all the channels are -9.5db except LFE??? I know that is normalized matrixing for mix clipping avoid...but...Why no LFE attenuate too?? I don't know what you thinki'n when do this....i know, i known, do you like basses very much....i note this.

Really speaking, i don't know what matrix is it, if exist one like this...

Really i don't like the idea of putting the LFE control level in 0.33 (-9.6db) for an "harmonic"  downmixing task.

Could you fix this? Please.

And...could you add front channels level controller too?? This is for a more flexible downmixing. Please, please, please, please....

greetings.

Sorry my bad english. Victor, from Argentina.

You might want to try the new Matrix Mixer.

What is the "new matrix mixer"?? How manage the mix this "new matrix mixer"?? Nobody knows...Can you post how?

It's all channels -9.5db in the new matrix?? Or the very loud LFE stays in place??

The only way for me, i think, is to ELIMINATE all rare matrixing and let the user levelling channels as they likes.

Please DEVELOPER listen to me.....
