How to use ODAS on mic array v1 with computer?

[chad1023]

Which version is your board?

If your problematic subject is the ReSpeaker Mic Array - Far-field w/ 7 PDM Microphones, where do you connect it to? The ReSpeaker Core or PC?

PC

Question

I connect the microphone array with computer and run ODAS_WEB in Ubuntu, but it didn't work.

Thanks for help

Have you change the mic array's default firmware? if not, please change to the 8 channel raw audio firmware first. See https://github.com/respeaker/mic_array#requirements

Yes, I have changed. I run the sample code in mic_array successfully. If I should change the config file or core file in ODAS?

[xiongyihui]

Yes, you should use https://github.com/introlab/odas/blob/master/config/respeaker.cfg as the config file

I use the respeaker.cfg as the config file and Change the sound card number according to this: https://github.com/respeaker/mic_array#requirements

But it didn't work.

Oh, I think we should change the cfg file a little bits.

Settings of ssl:

        # format = "undefined";
        format = "json";

        interface: {
            # type = "blackhole";
            type = "socket"; ip = "127.0.0.1"; port = 9001;
        };

settings of sst

    # Output to export tracked sources
    tracked: {

        format = "json";

        interface: {
            # type = "file";
            # path = "tracks.txt";
            type = "socket"; ip = "127.0.0.1"; port = 9000;
        };

    };

I run it successfully, but there is no active source location.

The two lines are the detected sources. It seems that the sphere is not displayed in your ODAS Studio.
