Please set the VALUE parameter of Constant node of MAIN as follows.
– Set type to subnet_param.
– Enter ARG1 in the text box.
If you execute network file on terminal, you can give an input WAV file by specifying a file name with the first argument.

e.g.) ./network.n ./your_input.wav

Please set no values to all parameters of InputStream node in MAIN.

SourceTracker’s Thresh is a parameter that judges whether the MUSIC spectrum power
of the node connected to the preceding stage such as LocalizeMUSIC or not exceeds the threshold value.
It is difficult to make physical meaning to the value of the MUSIC spectrum itself.
Therefore, there is no unit.

For MUSIC spectral power when LocalizeMUSIC is connected, please refer to the following formula (15) and (16) in the document.
http://www.hark.jp/document/hark-document-en/subsec-LocalizeMUSIC.html

Thresh differs depending on the user’s environment, so there is no recommended value,
but you can know roughly the proper value by the following method.
1. If you set DEBUG parameter to true on the LocalizeMUSIC node, the MUSIC spectrum power in each direction included in the transfer function is output to the stdout.
2. In the result of this stdout, the value of the column whose numerical value rises when you speaking is the value of the MUSIC spectrum power in the sound source direction.
3. You can check the average of the values shown during the speaking periods and the average of the values shown during the silence periods.
4. You fine-adjust the intermediate value of the two values confirmed in step 3. as the initial value of SourceTracker’s Thresh parameter.

– Case.1
If you are using Ubuntu distribution, you can easily get source codes using the following method.

apt-get source <package-name>

e.g.) In case of the HARK basic package’s source codes and HARK-Python source code required.
apt-get source harkfd hark-sss hark-python

– Case.2
When you need an older version than the one you are currently releasing,
or
If you are using another Linux distribution (e.g. Debian, Mint, Fedora, Cent OS, Red Hat, Vine, etc…)
you can download source code in tar.gz or tar.xz format from the following location.
However, we do not officially support other than Ubuntu.
If you use an OS other than Ubuntu, you may need to change configure.ac or/and Makefile.am.

http://archive.hark.jp/harkrepos/dists/<code-name>/non-free/source/

e.g.) Xenial, Trusty, Precise are as follows.
http://archive.hark.jp/harkrepos/dists/xenial/non-free/source/
http://archive.hark.jp/harkrepos/dists/trusty/non-free/source/
http://archive.hark.jp/harkrepos/dists/precise/non-free/source/

If you need a more older version please download from the bottom of the bottom on this page.
