The analog analogy is the plate or spring reverb as a fixed characteristic.  By the 2010&#8217;s, realtime software implementations  became more widely available for PC&#8217;s.  Of note, was Matt Rogalsky demonstrating the use of convolutions at a workshop at Harvestworks as part of our Rainforest V project there (ca. 2009? at Governors Island).<\/p>\n\n\n\n<p>In the next years, we (Matt, John Driscoll, I) assembled and extensive library of the sonic &#8220;impulse&#8221; recordings starting with each of the Rainforest V collections.  <\/p>\n\n\n\n<p>With an evolving interest in virtual sound objects and other performance opportunities, around 2015-2017 I worked on the based of the Max patch for variable number of preformers, standard or instrumental loudspeakers.  <\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignright size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"503\" src=\"https:\/\/composers-inside-electronics.net\/cie-wp20\/wp-content\/uploads\/2025\/05\/image-7-1024x503.png\" alt=\"\" class=\"wp-image-5193\" style=\"width:228px;height:auto\" srcset=\"https:\/\/composers-inside-electronics.net\/cie-wp20\/wp-content\/uploads\/2025\/05\/image-7-1024x503.png 1024w, https:\/\/composers-inside-electronics.net\/cie-wp20\/wp-content\/uploads\/2025\/05\/image-7-300x147.png 300w, https:\/\/composers-inside-electronics.net\/cie-wp20\/wp-content\/uploads\/2025\/05\/image-7-768x378.png 768w, https:\/\/composers-inside-electronics.net\/cie-wp20\/wp-content\/uploads\/2025\/05\/image-7.png 1318w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Graph view of output from the a-clifford fractal generator<\/figcaption><\/figure>\n<\/div>\n\n\n<p>The patch allows a performer to select a set of impulse files and uses the a-clifford fractal generator from the MAX third party Chaos Library fractal generator to use the impulses as both source and resonant filter.

The convolution reverbs served as virtual microphones as an alternative to the contact microphones in the generation of material used for Rainforest IV.  <\/p>\n\n\n\n<p>John and I have then used the impulse library and convolution reverbs in various other work such as Cluster Fields.  <\/p>\n\n\n\n<p>As an aside, see also CIE at MoMA in 2019 performance of David Tudor&#8217;s <em>Forest Speech<\/em>. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Future_Usage\"><\/span>Future Usage<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Of interest is adapting this for use in an interactive installation possibly as one of the elements was a consideration for <a href=\"https:\/\/composers-inside-electronics.net\/cie-wp20\/eclipse-2025\/\">Eclipse August 2025<\/a> or other projects.<\/p>\n\n\n\n<p>Variations include providing visitor with a appropriate control surface to to influence the automations inherent in the work. <\/p>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Click here for notes on computer hardware and operating system considerations<\/summary>\n<p>The orignal a-clifford fractal generator MAX third party plugin was not been ported from Apple&#8217;s Intel architecture to the new Apple Silicon.

Other possibility is running Max under Windows.<\/p>\n\n\n\n<p>As of March 2026, I was able to create a replacement version of the long deprecated object in javascript for MAX and have the patch now working again.
