node.js - odas web 执行时出现错误 "sink pots: cannot connect to server"

Question

我正在尝试将 odas_web 与 Respeaker Mic Array V2.0 结合使用来执行声源定位和跟踪。设置相应的配置文件后启动 odas 时，GUI 不提供任何数据(它保持原样!)。

此外，当我执行命令“./odaslive -c ./-v”时，会导致以下错误；

"sink pots: cannot connect to server"

我使用的配置文件是:

# Configuration file for XMOS circular sound card

version = "2.1";

# Raw

raw: 
{
    fS = 16000;
    hopSize = 128;
    nBits = 16;
    nChannels = 6; 

    # Input with raw signal from microphones
    interface: {
        type = "soundcard";
        card = 1;
        device = 0;
    }
}

Answer 1

这意味着 odas 已启动，无法找到 ip = "127.0.0.1"处的套接字服务器； 端口=9001；或设置为在本地网络中发送潜在源地址，其中已经运行 odas 的 Web 部分，例如

potential: {

        format = "json";
        interface: {
            type = "socket";
            ip = "192.168.0.102";
            port = 9001;
        }; 

或者这样设置:

potential: {

        format = "json"; 
        interface: {
             type = "file";
path = "potential.json"; 
        };

    };

将发现的电位保存到文件中，以供将来调试
