Web Instrument Count Experiment (WICE)

    Our research group at the International Audio Laboratories Erlangen is working on some topics in music perception. We ran several experiments to find out: What is the number of instruments in polyphonic music humans can estimate correctly?
    To compare our internal results with a broader user base, we published a new web-based listening experiment at WICE : Web Instrument Count Experiment

    We would be very thankful for your participation. The experiment takes ~10 minutes to finish.

    Any feedback or questions about the experiment are very welcome!

    Interesting experiment. I tested in the top 2% of those who have taken it. (my score was 1204 for getting 9 out of 12 correct). I would hope so, if I had scored worse it would not say much for my listening skills as an engineer. Try it!

    Good for you Jeff, That's pretty impressive. Thats your acoustic experience showing there!


    I got :

    Congratulations! You achieved a score of 845

    72.86% of all listeners didn't achieve a score as high as yours!
    Number of correct items: 7/12

    I'm going to try it again. Looks like we can have fun with this.

    I'm surprised more people here haven't tried this, Where is everyone?

    I tried a few times and was all over the map. Its a cool test. I haven't looked to see the answers, going to do it again so don't tell.

    I just have to beat you lol!

    Just tried it with HP on:

    Congratulations! You achieved a score of 1045

    96.08% of all listeners didn't achieve a score as high as yours!
    Number of correct items: 8/12.

    Interesting results. Did you look at them? On a previous one I got those right. Pays to not over think.

    But an interesting experiment and company.

    I think its worth supporting here. Try it.

    bayerha,

    Could we have feedback from you or your company, please?
    I'm particularly interested in perception-based spatial audio signal processing.

    I would like to know how this music was processed because, to my ears it doesn't have good spacial separation. However, I am 56 so is that me?
    My analog summing system ( or my personal approach) would have separated all these instruments much better than inside the box. This is how I hear most music today. Digitally summed music is one big mash-up. Maybe this is why I appreciate and invest in a recording and mixing system that can process and separate audio more than others?



    Can you tell us more?
     
  9. Some Details

    Dear Forum,

    thank you all for your interest and your participation. Your input is very helpful and we are very glad, that find our experiment interesting.

    We are actually an independent research institute at the University of Erlangen/N├╝rnberg in Germany. We work in close collaboration with the Fraunhofer IIS (Home of MP3) in nearly all fields of audio research.

    Sure. I can try to answer your questions as good as possible. Please keep in mind that more information about the intention and background of the experiment can spoil future participants so I will keep it short here.

    I am wondering that you even hear any spacial separation at all. Because the files are completely mixed in mono. This is totally intended as we want to focus on other cues than spatial ones.

    Techniques and methods that are usually applied by audio engineers to let some instruments better stand out in a mix have not been considered here. The mixing has been done as "raw" as possible. We have only added some basic convolutive reverb to the tracks.

    I can post further details when we have finished the experiment and we have published the results if you are interested here.

    I thought it was mono but to be honest, I didn't check. My mind struggled with it so I must have done a subconscious stereo widener in my mind to try and separate the sounds!

    Thank you! I look forward to your next reply.

    I have tinnitus...so didn't do very well, test is over :)

    Lucky for me it doesn't hinder my job.
