BoxFreak Wrote:have you looked at other formats than that Behringer one?
No where can I find this information? I only found the linked documentation.

BoxFreak Wrote:Another feature I would like to see implemented is possibility to automatically change sound field from stereo --> multichannel and vice versa according to type of 2-channel source material. For example outputting stereo -music through 2 main speakers, and after that watching video with 2 channel soundtrack would be output through 5.1 speakers. I can do it now by selecting different sound field on my receiver, but it would be cool if this could be automatic inside Kodi.
I thought about the implementation of an ADSP-Profile Manager, but that's a plan for a future a version. The next steps will be to finish the addon adsp.xconvolver and make adsp-addon-handling more stable.

I´ll try to find my own correction file for MiniDSP-subwoofer and share it here when I´m at home. Maybe it helps...

Thanks for that example. This output looks much better, because we can directly see the coefficients.
What export settings should I choose in order to obtain this format?
Do you know if it is possible to control REW with command line commands? Or does it have a remote control interface?


RE: Adding Audio DSP Plugin to AddonManager - BoxFreak - 2015-02-01

That output is for MiniDSP, so choose that.

Don´t know about controlling. But I wouldn´t need to do that, because my measurement setup is on my laptop and not on my HTPC. So it´s enough if Kodi understands those correction files created with other PC and REW. You can´t run REW on every platform anyway.

With MiniDSP on my subwoofer I first run REW measurement with my laptop, then export correction file to that format, and after that I upload it to MiniDSP via MiniDSP´s Windows interface.

I would like to know if using this version of KODI with Audio DSP plugin is in anyway skin related? Does a skin need to support this plugin, or it should work on all skins for KODI?

In short, the skin should support AudioDSP Manager and the AudioDSP OSD Dialog. If there is no skin file that comes with the adsp-addon we have a fallback to confluence skin.

Tanks for sharing your experience.

Yeah it is definitely nice if we can use those REW MiniDSP measurement files.

REW runs on Windows, Linux and OSX Blush

But I need it, because Kodi and measurement is on the same PC Big Grin
If there is a solution I will post that in an other thread.


RE: Adding Audio DSP Plugin to AddonManager - qzem - 2015-02-04

@wisler

Thanks for your answer, I will ask the author of Nebula skin if he could support this addon. BTW will you compile KODI 14.1 with this addon included, or you are planing to do some updates regardin addon before?

Well I just do measurement every now and then, if I move my speakers or change my equipment, or something like that. So I don´t think it´s necessary to be able to command REW through Kodi. But if it would be possible, why not. Smile

Sorry at the moment I have no plans to compile Kodi 14.1 with adsp-addon-handling. But I hope that we get adsp-addon-handling very soon in Kodi's master branch.
Just wait a little bit before you ask him, because I there is still some work to do at the AudioDSP Dialogs. Maybe he then has to do the work twice.

My plans are:
  • start developing adsp.biquad.filters (Biquad filters) with Native (C-Implemenation), SSE3 and AVX optimizations
  • finish adsp.xconvolver with Native, SSE3 and CUDA optimizations



RE: Adding Audio DSP Plugin to AddonManager - qzem - 2015-02-06

No problem he said that he will implement support when the addon will be included in Kodi. I hope that you will manage to get this addon in master branch soon. Thanks for great work!


RE: Adding Audio DSP Plugin to AddonManager - qzem - 2015-02-16

Just checking out if there is anything new going on here Smile? I am realy looking forward for this plugin to be merged in Kodi.


RE: Adding Audio DSP Plugin to AddonManager - alwinus - 2015-02-16

Currently are other changes which also related to it, e.g PVR addons (same build system) where the binary system comes in, this must done first. But several helper parts from DSP becomes currently added to KODI. I goes slow but it come Blush. After the current changes are in, I to a update of my branch to the current KODI github version.

Yeah sure there is something new. In the last days I started to develop a new plugin (adsp.biquad.filters). With it we will have a audio equalizer for Kodi. When it gets to a stable version, I will create a new thread for it.
