FreeSurround AudioDSP add-on for [Kodi] (http://kodi.tv)

FreeSurround is based on foo_dsp_fsurround from pro_optimizer for foobar2000 0.9.x.

This add-on is the equivalent of your hi-fi receiver's Dolby ProLogic II button (except that it uses a different algorithm) for Kodi.

It's purpose is to decode surround information from your stereo music (including mp3) to produce multichannel output.

It works with any stereo music containing surround information like the following compatible coding schemes:

• Dolby Surround
• Dolby ProLogic
• Dolby ProLogic II
• SRS CircleSurround
• SRS CircleSurround II
• DTS Neo:6
• Lexicon Logic7
• Stereo Quadrophonic (SQ)
• Quadrophonic Stereo (QS)

Change LFE output settings

Currently you have to edit the generated "ADSPFreeSurrAddonSettings.xml" changed by hand to edit the cut off frequencies of the LFE channel. Set bassredirection to true and change the settings. E.g.

        <bassredirection>true</bassredirection>
        <lowcutoff>40.000000</lowcutoff>
        <highcutoff>90.000000</highcutoff>

Normally it's a part of the AudioDSP post processing system that's why it is not directly editable from a Kodi window!

Build instructions for Kodi's binary add-ons

When building the addon you have to use the correct branch depending on which version of Kodi you're building against. For example, if you're building the Jarvis branch of Kodi you should checkout the Jarvis branch of this repository. Addon releases are also tagged regularly.

For further instructions replace {addon-id} and {org} with the repository- and the Github organisation-name. E.g. https://github.com/kodi-adsp/adsp.basic.git results in {addon-id}=adsp.basic and {org}=kodi-adsp

With the following instructions the add-on files will be placed in ../../xbmc/addons. Consequently this adds a system add-on, which can be used direclty if you build Kodi from source.

Linux

1. git clone https://github.com/xbmc/xbmc.git
2. git clone https://github.com/{org}/{addon-id}.git
3. cd {addon-id} && mkdir build && cd build
4. cmake -DADDONS_TO_BUILD={addon-id} -DADDON_SRC_PREFIX=../.. -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=../../xbmc/addons -DPACKAGE_ZIP=1 ../../xbmc/project/cmake/addons
5. make

Windows

Use the visual studio command line or run call "%VS120COMNTOOLS%..\..\VC\bin\vcvars32.bat"

1. git clone https://github.com/xbmc/xbmc.git
2. git clone https://github.com/{org}/{addon-id}.git
3. cd {addon-id} && mkdir build && cd build
4. cmake -G "NMake Makefiles" -DADDONS_TO_BUILD={addon-id} -DADDON_SRC_PREFIX=../.. -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=../../xbmc/addons -DPACKAGE_ZIP=1 ../../xbmc/project/cmake/addons
5. cmake --build "%cd%" --target "{addon-id}"
