お問い合わせありがとうございます。
HarkDataStreamSenderノードはsocket通信のTCP/IPプロトコルで バイナリデータ を送信します。バイナリデータですので、toStringやUTF-8変換などを行っては いけません のでご注意ください。
データ構造につきましては下記URL(HARK-Documentのノードリファレンス、HarkDataStreamSenderの項)の「データ送信の詳細」以降に記載しております。
https://www.hark.jp/document/hark-document-ja/subsec-HarkDataStreamSender.html記載している情報ですが、C/C++の型情報に基づいておりますのでnode.js上でのデータの扱い方を簡単に書かせて頂きます。node.jsでは特定のモジュールを使用しなければ64bit整数を扱えないようですが、下記のような構造ですので時間情報が必要な場合でも、精度の高い時間情報が不要でしたらフレーム数(sampling=16kHz、advance=160の場合1フレームあたり10ms)から算出する事が可能です。
buf = new Buffer([0x04, 0x00, 0x00, 0x00, 0xa0, 0x00, 0x00, 0x00 ... 受信データ ...]); // --- hdh_type = buf.readInt32LE(0); // HD_Header (type) : SRC_INFOを意味する 0x00000004 hdh_advance = buf.readInt32LE(4); // HD_Header (advance) : ADVANCE=160を意味する 0x000000a0 hdh_sec = buf.readInt32LE(8); hdh_sec *= (2 ** 32); // 恐らくモジュールを追加しなければオーバーフローします hdh_sec += buf.readInt32LE(12); // HD_Header (tv_sec) : 1960/01/01 00:00:00 からの秒数 hdh_usec = buf.readInt32LE(16); hdh_usec *= (2 ** 32); // 恐らくモジュールを追加しなければオーバーフローします hdh_usec += buf.readInt32LE(20); // HD_Header (tv_usec) : 同上からのマイクロ秒(秒数未満) // --- srcs = buf.readInt32LE(24); // Sources : 音源数(下記HDH_SrcInfoの個数) // --- for(var i = 0; i < srcs; i++){ src_id[i] = buf.readInt32LE(28+i*20+0); // HDH_SrcInfo (src_id) : 音源iのid src_x[i] = buf.readFloatLE(28+i*20+4); // HDH_SrcInfo (x[0]) : 音源iのx座標 src_y[i] = buf.readFloatLE(28+i*20+8); // HDH_SrcInfo (x[1]) : 音源iのy座標 src_z[i] = buf.readFloatLE(28+i*20+12); // HDH_SrcInfo (x[2]) : 音源iのz座標 src_pow[i] = buf.readFloatLE(28+i*20+16); // HDH_SrcInfo (power) : 音源iのMUSIC power } // ---毎フレーム上記のようなデータが届きます。また、音源数 i は定位した音源が無ければ 0 となる事もあります。その場合はループ内のデータ構造(HDH_SrcInfo)部分は受信しません。
デカルト座標から極座標に変換される場合は、下記URLの座標系の説明をご参照ください。

I identified the cause by checking your network file (PreMeasuredNoiseSSL.n).
The problem is very simple, the Gener_Pre_Measured_Noise_SSL sheet must be set to “iterator”. Right now it is set to “subnet”.
In HARK, processing is repeated on an input stream on a frame-by-frame basis.
Therefore, the type of the sheet created by the user placed next to the InputStream node in the MAIN sheet should be an iterator in general.
The name of the sheet can be arbitrarily given, but as in the cookbook example, we often use the name “LOOP” for the sheet to be processed repeatedly.How to change:
Left click on the tab of the target sheet and select it, then click “Change to iterator” from the pop menu displayed by right clicking.When creating a new sheet:
If you click on the “+” button, You can change the “Type” parameter from “subnet” to “iterator”.Best regards,
m.takigahiraPlease try the following.
Run the sample network file I posted last time and check if there is an error.If an error occurred, the HARK installation itself may have failed. First, try reinstalling HARK. If there is no reason to use the current version, please consider updating to the latest version. If an error occurs during installation, please provide detailed error information, we can help you.
If it can be executed without error, the noise correlation matrix file named cm.zip will be saved. In that is the case, there are two things you can do. The first is to edit the network file I posted. The second thing is to post your network file to this thread. We want to take a look at your network file.
Notes:
I confirmed that the sample network file “sep_rec_offline_output_cm_test.n” I posted last time can be executed even in the environment of HARK 2.2.0. Since it is a network file that does not use the new functions, so you probably can execute it with HARK 2.1.0 or later.The reason for downloading the HARK 2.3.0 recognition sample set is that the set of input WAV file and transfer function file can be easily obtained. Of course, recognition scripts for kaldi are only supported on hark 2.3.0 or higher. It will not work on the version you currently have.
Best regards,
m.takigahiraReference information
You can try the attached sample network file.
wget http://www.hark.jp/networks/HARK_recog_2.3.0.1_practice2.zip unzip HARK_recog_2.3.0.1_practice2.zip cd HARK_recog_2.3.0.1_practice2 cp <your download path>/sep_rec_offline_output_cm_test.n ./ batchflow ./sep_rec_offline_output_cm_test.n ./2SPK-jp.wavSorry, this sample audio file is in Japanese.
Best regards,
m.takigahira– 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.
