    What a pleasant surprise for an insomniac night, “shopping for” assorted videos on hearing science. Thank you for using our interspeech paper on this topic! Greetings from Lei He.

    I am so incredibly grateful for the time and effort that you invested to have us all know about these concepts - for free... Thanks so so much for this mindset!

    Hi! Do you have any resources on how you divided the original sound into the 8 frequency channels at around 6:50?

    At 7.45, is this similar to empirical modal decomposition ? See emd on pypi :)

  • @lelabodezaocreationdinstru3569

    Could this could be implemented in python with parselmouth ?

    Hi. I have found the paper for PRAAT script. But how can I simply copy the script?

      follow the links in the description. You can copy and paste the code into a text document.

      @@listenlab_umn Thank you sir, it worked so well! Just curious is that possible to extract the envelope in the form of numerical values, and export all to Excel? I'm trying to correlate singing signal envelope with brain signal envelope. Already done so for brain signal. So if I can extract the numerical values for audio signal from PRAAT it would be very helpful to run the correlation test using SPSS afterwards.

      @@hahar18 yes, you can export any object in praat in various ways. You can cast it to a table first and then save as csv.
      You might be interested in using a more powerful platform than excel. R or Python are very useful languages to know.
