    Voss algorithm to generate 1/f noise

    Seems very elegant and easy to digest. I found an interesting paper, adding the Voss Constraint and testing it with a melody generation.

    Simple no, but I am studying it.

    I am grateful for this patch already and I definitely understand your point of view about what lies beneath certain things to sound good. Music is a subjective experience and besides algorithms, is based on other factors too. I have a side music project based on improvisation where most of the sounds are adjusted by ear at the time of the performance. However we also like to explore and sometimes better understand the mysteries around all these beautiful phenomena.

    [array random]

    I had overlooked that object, definitely worth a try by using it maybe as an intermediary between 1/f noise distribution coming from other sources and what I am trying to achieve (I see now an example with a histogram). I agree there many other interesting functions for sound synthesis besides 1/f noise but I had to start from the basics while I am trying to accomplish a patch for self-generative soundscapes.

    Hey all,

    I am flirting with the idea of using 1/f noise (pink noise) as a control signal to various PD parameters. As some of you may know, the 1/f noise equation is commonly found in nature and various natural systems. It is characterized by a frequency power spectral density that decreases as the frequency increases, following a power-law distribution. It can be observed in many natural phenomena such as earthquakes, wind, even in the heartbeat. I am thinking-exploring ways (and the know how) to apply this characteristic to control various parameters within a self-generative future patch, from microscopic to macroscopic level (in either audio or control rates). Things like ADSR curves, to the density of pitched sounds within a time framed composition and everything in between.

    As an example, 1/f noise can be observed in the sound of Rainfall The different raindrop sizes result in variations in sound frequencies and amplitudes. Suppose one drop of rain is synthesized, how could you apply the 1/f noise to generate a complete Rainfall realistically?

    Any ideas and reference to other patches exploring this idea are welcome.

    @lacuna It worked! thank you!

    @lacuna This is exactly what I was looking for, although at first read it is difficult to understand exactly how it works... How do I pass the filename from [text get $0-dirfiles] into [open] and then [readsf~] ?

    I was looking into the [makefilename] solution from another patch I found yesterday and then your reply... Great! There so many ways to make something possible in pd, the quest is to find the most elegant one. Thanks a lot! I will share the patch in the forum when it is ready.

    Hey all,

    I am following this forum silently for a while, feeling grateful for all this effort here. I am making a patch for a sound installation [attached] and I need some help making it more convenient for myself and others. The patch is relative simple, randomly playback samples from the hard-drive using the readsf~ object. At the moment it directly opens and play the samples from a specific location on the drive. This is a problem if I want to share the patch with other users as they will need to change the pathname I have used on my computer to access the samples. Additionally, it's a bummer for myself if I want to easily change the samples and test some others. I have to change each pathname manually. Ideally I will want to throw the samples into pd and leave it do the rest with my patch.. Any help will be greatly appreciated.
