7.1 SDDS Format

Audio Plugins
1 
​

Hi All,

 

I'm tryint to get my plugin to support 7.1 SDDS format in Pro tools. At the moment the plugin descriptions in the AAX wrapper allow it to load into a normal 7.1 track, but I can' load it into a 7.1(SDDS) track.

 

If I'm not mistaken, by default the AAX wrapper creates a property map for 8-channel support with AAX_eProperty_InputStemFormat assigned to AAX_eStemFormat_7_1_DTS:

juce_AAX_Wrapper.cpp


static AAX_EStemFormat getFormatForChans (const int numChans) noexcept
    {
        switch (numChans)
        {
            case 0:   return AAX_eStemFormat_None;
            case 1:   return AAX_eStemFormat_Mono;
            case 2:   return AAX_eStemFormat_Stereo;
            case 3:   return AAX_eStemFormat_LCR;
            case 4:   return AAX_eStemFormat_Quad;
            case 5:   return AAX_eStemFormat_5_0;
            case 6:   return AAX_eStemFormat_5_1;
            case 7:   return AAX_eStemFormat_7_0_DTS;
            case 8:   return AAX_eStemFormat_7_1_DTS;
            default:  jassertfalse; break;
        }
        return AAX_eStemFormat_None;
    }

                }
            }
        }
    }

​​Is there any way that I can get the plugin to support both 7.1DTS and 7.1SDDS formats in Pro tools?
