But they aren't. They would be without Dolby Headphone.

The Dolby Headphone site states that DH can reproduce a "7.1-channel surround sound experience", given the right source material. Is there any indication that this is supported by the DolbyHph.dll implementation? Because that would be *very* interesting...

Nevermind -- that requires a virtual speaker system. (So who brings that to foobar? )

I'm using portable version of foobar
any chance for support relative path in this plugin config?
would like to use ./components/ path for my dolbyhph.dll instead of C:\Program Files\...
?

Don't put the DLL in the components folder but in the main folder. And yes, the dot-notation works, I'm using it myself:
Code: [Select]
.\DolbyHph.dll

thanks, just trying to set it up
I can't use .\ path in foobar prefs, I go and edit via notepad foo_dsp_dolbyhp.cfg,
when I change from C:\Program Files (x86)\foobar2000\dolbyhph.dll to .\dolbyhph.dll I will have the following error while running foobar:
Code: [Select]
---------------------------
Error
---------------------------
Error reading configuration file (Unsupported format or corrupted file).
Continue?
---------------------------
OK   Cancel
---------------------------

any other place where I can set it up?

It was possible in the old version, I've probably removed it later for some reason. Depending on "current directory" is never very reliable anyway.
Try the new version.

Dolby Headphone DSP Wrapper v1.4
(obsolete links removed)

Changes:
  • Added an option to remember path to DOLBYHPH.DLL relatively to foobar2000 installation folder.
  • Some internal stability fixes and refinements.
  • New SDK used, requires foobar2000 1.0.

I can see the problem now. It seems like the location field was editable in an earlier version. I wonder why it isn't in the current version. You might want to look for an older version, edit the field by hand, save your DSP preset(s) and then switch back to the current version.

So, feature request: Make the field editable again.

Edit: Okay, never mind.

sounded very, very nice

Hi. Noob around here. First post

I'm trying to follow this suggested configuration (a DSP stack of: Channel Mixer -> VST host bridge -> V.I plugin for upmix -> Dolby Headphone Wrapper DSP -> Advanced Limiter), but I'm failing at the VI plugin for upmix step.

After running the VI Studio installer, it seems I should get a VI.dll file somewhere in my system. I've already searched for that file on my system, and it's definitely not there.
Any idea what could be going on? Is there any place where I could download that particular file? (on VI Studio website, there is a VII.dll file, but I'm not sure that's what I'm looking for).

Thanks in advance. And thanks also to both the author and maintainer of this plugin, which I'm just discovering...

I would use Channel mixer for upmixing and DH wrapper afterwards, no VSTs or anything like that
There are even Dolby upmixer components for foobar, but Channel mixer is enough for me

I'm using foobar 1.0.3 and the latest version of the dsp (1.4.1), as well as the latest version of the dolbyhph.dll (1.10.0.270). The wrapper is telling me that the dll is valid and is the correct version, but when I have the dsp active, there is no audio output whatsoever. Even if I deactivate the dsp, foobar requires a restart before I regain output. I checked through all the other dsp's I have active and none of them are presenting the problem. It's probably something stupid on my part, but even so, I don't know what.

I'm usually not a fan of DSP's that radically change the music but this makes listening for long periods a lot easier. I like this.

For those that upgraded to foobar2k 1.1 and are getting:
Quote
Error: [foo_dsp_dolbyhp] Unable to load selected DLL, please check file availability or select a valid one.

Be sure to configure this plugin to point to the new location of dolbyhph.dll

I really like the effect this gives to stereo audio, and it's great for those few 5.1 tracks I have, but I'm wondering where the limitation is preventing sample rates higher that 48 KHz from working properly. (As others have noted, the effect is lost on stereo audio at higher sample rates, and the plugin actually gives an error with 5.1 audio at higher sample rates.) I know some sound cards do support this. Does the dolbyhph.dll library just not support higher sample rates, even in the newest versions? Either way, great work with this plugin.

See this post (including the quote) for a possible explanation.

Indeed, though that post doesn't explain exactly why this happens. It is entirely possible that the plugin itself is in some way causing that effect. I mainly asked because I saw no mention of the error when trying to run 5.1 audio at a sample rate higher than 48 KHz through the plugin, as opposed to stereo audio which doesn't cause an error but also doesn't sound correct. I fully expect that this is a limitation of dolbyhph.dll, even the latest versions, but it would be nice to have a definitive explanation from the plugin author for all who might be wondering to see.

I'm not getting any errors with my SB Audigy 2 at 24/96 5.1, in fact, I don't notice any difference between using this resolution or downsampling to 48khz.

That's interesting, since it's definitely this plugin generating the error. I tried placing a resampler before and after this plugin so I know exactly what the sample rate going into each plugin is. The last resampler can be set to 96 KHz without any problem, but as soon as the first resampler is set to 96 KHz and the input is 5.1, I get an error saying unsupported format 96000 Hz / 24-bit / 6 channel. This happens even if the last resampler is set to a value other than 96 KHz, implying that it's this plugin giving the error, since it's the only one that should be getting an input matching the error. Moreover, if the first resampler is set to 96 KHz and the input is stereo, then the output sounds the same regardless of whether I have this plugin in the chain or not, implying that the plugin is not giving an error with stereo input above 48 KHz, but isn't doing anything at all. I'm using dolbyhph.dll version 1.10.0.270.

The built-in filters in dolbyhph.dll (at least version 1.20.0276 here) support only sample rates 48000, 44100, 32000, 22050, 16000, 11025 and 8000 Hz. If the input data has any other sample rate, the nearest lower one is simply used instead.

I'm using the Dolby Headphone Wrapper DSP nearly a year and I like it very much. So thanks to the developer.

I have a question. A 6.1 dts File from a video DVD can be played with Dolby Headphone. But why can't be a 6.1 Wave File  played with Dolby Headphone?

What differences in behavior are there? I don't have a 6.1 file to check.

Nevertheless, I know that the default format with biggest number of channels supported by the library is 5.1 (FL, C, FR, SL, SR, LFE). And anything else with greater number of channels will most probably use this format with mismatched input data and therefore result in random noise (or worse).
