       Show HN: Synesthesia, make noise music with a colorpicker
        
       This is a (silly, little) app which lets you make noise music using
       a color picker as an instrument. When you click on a specific point
       in the color picker, a bit of JavaScript maps the binary
       representation of the clicked-on color's hex-code to a "chord" in
       the 24 tone-equal-temperament scale. That chord is then played back
       using a throttled audio generation method which was implemented via
       Tone.js.  NOTE! Turn the volume way down before using the site. It
       is noise music. :)

       | Lovely! Edit: you might want to consider adding a limiter to the
       | output, it makes a lovely crackling effect but it's easy to
       | flatline the output until it fizzles out completely, it'd be more
       | curious to hear the denser textures.

         | Thanks! And thanks for that suggestion.
         | 
         | I added a limiter to the output and an envelope to my synth
         | object, but after a bunch of experimenting with different
         | settings for each, the flatlining effect was still there.
         | Throttling beyond the note+release's duration did fix it, but
         | that also removed the layering effect of overlapping chords. I
         | think some of those were interesting and wanted to keep them.
         | The last thing I tried was setting the attack to 0.01 and I
         | think that fixed the flatlining issue?
