Hi kohira,

Can you please upload the exact files that you are using – except for the ones already found in HARK_recog_3.0.0_practice2.zip. I will also need to know the exact steps that you performed to generate the files.

I know that what I am asking is a bit tedious on your part, but the items I am requesting are necessary in order for us to identify the problem/issue that you raised.

Regards,
HARK Support Team

Hi,

We’d like to know the node binary path and the version of that binary.

Can you please post the output of the two commands:
1) $ which node
2) $ node --version

Cheers,

Hi kohira,

There are sample files available for download in this link:
https://www.hark.jp/download/samples/

You might be interested in checking out the following files:
HARK_recog_3.0.0_practice2.zip
HARK_recog_3.0.0_IROS2018_practice2.zip

Please let me know if these are not the files that you are looking for.

Best Regards,

Hi kohira,

>> Could any body tell me how the TR created by calculation makes it worse than the one by measurement?

We alrady indicated in our documentation that Geometric-Calcuation-based Transfer Function Generation may have less quality as compared to Measurement-based Transfer Function Generation
depending on the environment. The reason for this is, the calculation does not take into consideration the effects of the possible obstructions in the environment during the recording.

See documentation: https://www.hark.jp/document/tf/generating_transfer_functions/Generating_a_Transfer_Function_Using_HARKTOOL5.html#_Toc518480855 (see figure 14).

So if the environment is not a “Free Space” environment, then the performance of the TR generated using Geometric-Calcuation will surely be lower than that of a TR generated using Measurement.

>> Or, is there any sample wave files obtained by HARK’s source separation, which have little cross talk for two or three sources?
I will ask the team if there is any avaiable sample save files that you can use.

Cheers,

Hi,

Before I can help you, I need to clarify: What is “TR”?

Hi,

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.

Cheers,

Hi Kohira,

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.

Hi,

There is documentation for HARK Transfer Function usage here:
https://www.hark.jp/document/tf/generating_transfer_functions/Generating_a_Transfer_Function_Using_HARKTOOL5.html

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.

Cheers,

Hi kohira,

The HARK Cookbook covers a broad range of topics.

In your case, are you referring to this specific topic: Sound Recording Network Sample – Windows? If not, please post the link of the specific HARK Cookbook topic that you are using so that we can help you verify and execute the correct command.

Cheers,
Earl

Hi Jm,

Can you please attach the actual network file that you used.

Cheers,
Earl
