HARK FORUM › network to separate sources
September 3, 2019 at 11:19 am #1160
I would like to setup a network to separate sources, where the position of each source is fixed to mic array. Now I have made a transfer function for that using HARKTOOL5-GUI on ubuntu, which name is tr.zip.
Should I connect any node to INPUT_SOURCES of GHDSS?
If so, why? in spite of everything is fixed, and what node?
Or, is there any sample network file for that?
Thank you.September 4, 2019 at 3:30 pm #1161
There is documentation for HARK Transfer Function usage here:
In section 4.2., Evaluating Separation Transfer Functions, it describes how to create a network for sound separation with a GHDSS node. Perhaps the steps provided in that section of the documentation can help you achieve what you want.
If you have further questions with the steps enumerated in the HARK Transfer Function documentation or anything regarding sound separation in general, please don’t hesitate to post it here.

For source separation under the condition where everything is freeze but for mouths, I think it would be achieved by using certain one node which outputs fix values of directions of sources instead of a set of nodes which are LocalizeMUSIC, SourceTracker … and Delay in Figure 6.56.
But I could not find out the one node yet.
Could you please tell me the node, if you know?

I am not sure which figure (Figure 5.65) you are referring to. Is it in this document: https://www.hark.jp/document/tf/generating_transfer_functions/Generating_a_Transfer_Function_Using_HARKTOOL5.html?
If it is not in the link above, can you please post the link of the documentation which has Figure 6.56? It will help me understand your question better if I can see the diagram.

Oh, sorry for big mistake!
That was “HARK Document Version 3.0.0. (Revision: 9272).”

Perhaps you can try using the ConstantLocalization node with the GHDSS node. ConstantLocalization allows you to output constant sound source localization results from multiple sound sources by explicitly specifying the angles or elevations.
An example of how to use this node with GHDSS is explained here: https://www.hark.jp/document/tf/generating_transfer_functions/Generating_a_Transfer_Function_Using_HARKTOOL5.html. See figure 45 in Section 4.2.1.
You can also read a more detailed documentation of the node here: https://www.hark.jp/document/3.0.0/hark-document-en/subsec-ConstantLocalization.html
Please let us know if this works for you.

The network in Figure 45 is what I needed!
I am trying the network. I will show result in any case.
