• improve asplib error detection to make it more stable
  
• create first version of the addon with adsp.template
  
• post some gui screenshots
  
• release first version for testing
  
• run some benchmarks
  

• EQ consists of digital Biquad filters with constant-Q design equations
  
• at the moment there is only a native [C/C++-Code] implementation
  
• variable amount of Biquads, e.g. it will be possible to have 10 Band- (beginner) or 31 Band-EQ (experts)
  

• presets (like vlc or other players)
  
• separate settings for all output channels of the configurated audio channel layout
  
• custom mode creation (create a custom eq for pre- or post mode of our new adsp-addon-handling feature)
  
• variable band configuration
  
• implement optimizations for SSE3, AVX, NEON,...
  
• integrate my LibXConvolver library to run an FIR-Filter as EQ with linear phase response

You may already been to these links already, but I'll post for others that may have an interest.

• Of course a equalizer with custom channel and frequency band configuration
  
• Low pass filter for subwoofer equalization (e.g. linkwitz transform)
  
• High pass filter to setup a crossover frequency for each audio channel
  
• Loading filter coefficients from other tools (e.g. room equalizer wizard)
  
• ...
  

• AddonHandler: this module is from adsp.template and has the job to create and destroy audio streams inside adsp.biquad.filters
  
• Postprocess Parametric EQ: is one of the possible processing modes that can be implemented. With this mode we will have an equalizer 10 band for each audio channel
  
• BiQuad Manager: is module which will allow us to store and load settings from processing modes and configuration of filters to xml files. The manager also handles to communication between the audio streams and user inputs with some simple message system.
  
• Dialog Parametric EQ: is the dialog you can use to configure the 10 band equalizer (sorry the first version will be very simple)

If I have something stable, I will post this here

Nice idea. If we find a paper or an algorithm that can do this then this is possible. With AudioDSP and some work, everything is possible.

• The addon has a post processing mode called parametric EQ, that you can use as an graphical EQ
  
• At the moment the mode process all speaker channels except LFE (subwoofer), which should be processed by another mode
  
• Each gain setting goes through all speaker channels
  
• Your current gain settings will be saved to an XML file in your user folder, which allows you to restore your old settings if you restart Kodi
  

• Testing phase which any volunteer can test my addon and post the issues on my github page. Please upload your kodi.log somewhere, which allows my to analyze your issue.
  
• GSoC starts and I will focus on my "Creating cross-platform room correction for Kodi" proposal
  

• Processing mode for the LFE channel (Low pass filter with variable cross over frequency)
  
• Crossover Filters (high pass filter) for speakers
  
• Custom mode creation, which allows you to create custom filters and processing modes
  
• Add Python support, which allows any one who is familiar with Python, SciPy and NumPy to create custom filters through a Matlab like environment
  
• Add a spin control, which allows to set individual gain settings for any speaker channel
  
• Write a good documentation
