  • Has anyone an idea how to make sound out of mandelbrot sets?

    i'm interested in math formulas that have a special beauty in it ... so the mandelbrot set is one of them.

    http://en.wikipedia.org/wiki/Mandelb...lia_island.jpg

    how can such a picture be transferred to music?

    i thought of laying a path or vector through the picture that represents the time line and all on the left side pans to the left speaker and all on the right side to the right speaker and every colour stands for a pitch.

    another approach can be to define a base-line (0 Hz) and a heights-line (22 kHz) and every point between gets its pitch from the distance to this two lines. here the colour might stand for tone-colour and the brightness for the volume.

    there are other ways too but none of them really satisfy my mind ... maybe there is a solution to bring all these spiraling forms in the prcture to music?

      Here a couple of ways:

      1. Photosounder - you can open the image in Photosounder, then the app converts it to sound. You can define the min/max frequencies as well as the pixel scan rate and several other parameters to vary the sound. You can also edit the image inside of Photosounder. Photosounder can be purchased with various licensing options. http://photosounder.com
      2. Another app that works in a similar fashion is Virtual ANS. It mimics the operation of the historic Russian ANS synthesizer. It is donation ware. http://www.warmplace.ru/soft/ans/
      3. Geosonix - This app does not produce a direct sound output. Instead, it generates MIDI note and CC messages. You can import an image, and use the image color information to modify the MIDI messages as the cursor(s) move along the defined path over the image. You will have to send the midi messages to your DAW or standalone synth or whatever. Geosonix is freeware. http://www.geosonix.com/top/

      Here's some audio examples from Photosounder & Geosonix using the same fractal image. Also, the folder contains the fractal image and screenshots captured while generating the audio examples, and some notes. https://www.dropbox.com/sh/qxlnd7agx...dW1xGQPSa?dl=0

        Thanks for this, WS! While I already knew about the other two, Geosonixis new to me. Going to take a look at it and see how it compares to the other two. :thumbsup:

          I really enjoy Geosonix. But I need to get back to it and spend more time with it. Some familiarity with Java Script will be immensely helpful, but one can punt by using copy/paste to modify the example JS scripts. You can also just drag & drop the paths and triggers. I have only a little experience with JS and I get along OK

          Best advice...RTFM! :biggrin:

                    How about iris from izotope, I think it also can import images?

                      I've been using a thing called Mandelbrot32 for years but it seems to have vanished, you can read about it here:

                      I've got a copy somewhere, I'll see if I can dig it out.

                            AHA!!!
                            Yes. Music from fractals. This is something I have experimented with myself a bit, tho I have yet to release any completed works with the results.
                            One of the oldest, yet still greatest, pieces of fractal software out there can render numerous of its fractal algorithms to sound. This wonderful software is Fractint.
                            http://fractint.org/
                            To use the sound options, you will need the DOS version, not the Windows version, found here; the file frain200.zip >> http://fractint.org/ftp/release.20.0/dos/

                            ... and now, well, the bad news ...
                            I went ahead and DLed the DOS version myself, as I didn't have it currently installed. Sadly, it no longer works under Win 7. One would need to install DOSBox and run it under that -- which would take some setup experimentation. I'll have a look into it and see how well I can get it to work, because it REALLY generated some very cool audio from various fractal algorithms.

                            EDIT: I figured I should upload a sample of what, exactly, can come out of Fractint. This is a recording of Mandelbrot orbits (orbits being how Julia sets relate to each region of any given Mandelbrot set).

                            As you can hear, quite interesting stuff.

                              looks similar to mandel32 ... thank's, I'll try it out
