Dear,

I managed to install and configure odas and odas-web. After enabling "separated audio", I get audio files like ODAS_140_2019-8-10_23-27-9-79_pf.zip Any idea what might go wrong?

Thanks, Bart

Sounds like you signal is clipping because the gain is too high. Try reducing the gain and tell me if it helps.

Thanks for the feedback!

Turned out to be the "Sample Rate" setting in ODAS Studio under "Configure". After changing the default 16000 to 44100 the audio improved.

My config: ` separated: {

    fS = 44100;
    hopSize = 512;
    nBits = 16;        

    interface: {
         type = "socket"; ip = "192.168.1.198"; port = 10000;
     #import in audacity as raw data with
     #signed 16 bit pcm
     #little endian
         #4 channels
     #freq 44100
         #type = "file"; path = "separated.raw";
    }        

};

postfiltered: {

    fS = 44100;
    hopSize = 512;
    nBits = 16;        

    interface: {
        type = "socket"; ip = "192.168.1.198"; port = 10010;
        #type = "file"; path = "postfiltered.raw";
    }        

};
