hi gang

I am trying to understand how to use .wav files to create something with Mandelbulber, I can not for the life of me understand how this is done, All I am getting are some really strange outcomes and it does not matter what I have tried I always get kind of random results.

Is there anyone with some example I could look at for me to understand fully how this is to be done.

thanks.

Sound file can be used for control of some fractal parameters or shaders parameters. After loading sound file, the sound is divided into 5 channels:
      s0 - sound envelope (absolute value of sound amplitude)
      sa, sb, sc, sd - selected frequency bands of sound
To animate selected parameter you have to put instead of parameter value, following string:
      "sx amp - where sx is channel name, amp is a gain for channel
For example, in IFS parameters you can put: rotation alpha = s0 1.0, rotation beta = sc -0.3. In this case rotation alpha will be animated by sound envelope (amplitude) and rotation beta by third frequency band.

Animation has to be rendered in key-frame mode.

Try to analyze example setting file: sound animation.fract

yeah I had a look at that file, it does not matter how I change the settings, what sound file I use it always does the same thing. Even skipping loading the sound file I get same results, changing all values to 0 same results, changing all values to 0 and for example rotation beta = sc -0.3 I get same results...

As well even if I change the endframe to something large, it always stops after 100 frames...

I still can not figure this out... Wonder if there is a problem with it on Windows...?

Saw this pretty interesting one on youtube...

Temporary I have postponed development of sound animation feature. I have completely removed it from the latest version of the Mandelbulber. There were to many bugs in this part of program which become when I have changed program structure. Now I also have to change completely handling of parameters, to make it more flexible. I will return with sound animation function in next releases. I'm sorry for the confusion.

Thanks for the update, I really look forward for the new version and the sound option as I really would like to work with that...

Keep up the awesome work...

Hehe, I had the exact same experience...

I also thought Window 7 was to blame

So I installed Linux, but realised that wasn't true.

Finally, my application for this forum was approved and I found this thread.

Sure, I could have looked before, but I wasn't in any hurry... Feels like I'd rather be running the program on Linux anyway

I'm terribly interested in this feature.
I will search for the most suitable version with the best sound-support myself... Don't want to waste your time
