      Hello,

      To get only separated wav files, I run a file my_sep_rec_offline.n which is obtained from a sample file sep_rec_offline.n by deleting sub_recognition.
      But it stops with a comment as below.

      Could you please point out bugs in the my_sep_rec_offline.n?

      Thank you.

        Hi Kohira,

        This error means that you missed setting an Output in your MAIN tab.

        Please do the following steps:
        1) Load your network file.
        2) Click on the MAIN tab.
        3) Right-click the ‘OUTPUT’ in the ‘MAIN_LOOP’ node
        4) Select ‘Set as Output’.
        ** This will pop-up a dialog, prompting you to input an Output name. You can just use the default value, OUTPUT. Then, click Ok.
        5) Click Save.

        After those steps above try executing the network. Please let me know if this solves your problem.

        Cheers,

          Hi,

          I executed a modified my_sep_rec_offline_2.n NOT by harkmw.exe but on HARK Designer 3.0.0, and got another error shown below.

          Should I add any node?

          Thank you.

            Hi kohira,

            The error you encountered has something to do with the input to the AudioStreamFromWave node. I reviewed your network file and noticed that you placed the value FILES inside the TYPE parameter of the InputStream node (see attached screenshot).

            Please remove the value and leave it blank. After that, save the network file and execute again. If there is still an error, kindly post it here.

            Cheers,

              Hi,

              I do thank you for your reviewing.

              I ran a network as yours, which I also change OUTPUT_GAIN from 1.0 to 20000.0 in a node of Synthesize.

              It resulted in very good.

              Thank you.
