Different approaches can be applied to the signals to produce different uncorrelated audio channels. The simplest decorrelation approach is to randomize the phase.<br \/>\nIn the context of multichannel sound production, decorrelation refers to the process by which one audio input is turned into several output signals with waveforms that appear distinct but sound the same as the source. This method extends the spatial image while avoiding unwanted comb-filtering artifacts.<\/span><span style=\"font-family: 'times new roman', times, serif;\"><br \/>\nA computationally efficient approach based on sparse convolution has been devised . This approach uses OVN (Optimized Velvet Noise) filters to achieve decorrelation, and this is the approach being used in the implementation of the Decorrelation AO.<\/span><\/p>\n<p><span style=\"font-family: 'times new roman', times, serif;\"><strong>Feature<\/strong><\/span><\/p>\n<ul>\n<li><span style=\"font-family: 'times new roman', times, serif;\">Available in the Immersive Audio section of GTT<\/span><\/li>\n<li><span style=\"font-family: 'times new roman', times, serif;\">Supports sample rates: 11025, 12000, 16000, 22050, 24000, 32000, 44100, 48000, 64000, 96000 Hz.<\/span><\/li>\n<li><span style=\"font-family: 'times new roman', times, serif;\">Supports block lengths: 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096.<\/span><\/li>\n<li><span style=\"font-family: 'times new roman', times, serif;\">Supports non-zero elements (to store position and amplitude values): 1 to 64.<\/span><\/li>\n<li><span style=\"font-family: 'times new roman', times, serif;\">Supports both Win64 and GUL platforms.<\/span><\/li>\n<\/ul>\n<p class=\"heading\"><span style=\"font-family: 'times new roman', times, serif;\"><strong>Decorrelation Properties<\/strong><\/span><\/p>\n<p>Below table describes about the <span style=\"font-family: 'times new roman', times, serif;\">Decorrelation<\/span> audio object properties and functionality.<\/p>\n<h2><span style=\"font-family: 'times new roman', times, serif;\"><img fetchpriority=\"high\" decoding=\"async\" class=\"alignnone size-full wp-image-25657\" src=\"https:\/\/audioworx.transfunnel.co\/old\/wp-content\/uploads\/2023\/10\/Decorrelation_properties.png\" alt=\"\" width=\"490\" height=\"504\" \/><\/span><\/h2>\n<table style=\"width: 97.251%; height: 56px;\">\n<tbody>\n<tr style=\"height: 10px;\">\n<td class=\"table-head\" style=\"width: 19.386%; height: 10px;\" width=\"132\"><span style=\"font-family: 'times new roman', times, serif;\"><strong>Properties<\/strong><\/span><\/td>\n<td class=\"table-head\" style=\"width: 152.136%; height: 10px;\" width=\"540\"><span style=\"font-family: 'times new roman', times, serif;\"><strong>Descriptions<\/strong><\/span><\/td>\n<\/tr>\n<tr style=\"height: 10px;\">\n<td style=\"width: 19.386%; height: 10px;\" width=\"132\"><span style=\"font-family: 'times new roman', times, serif; font-size: 12pt;\"><strong>Number of Channels<\/strong><\/span><\/td>\n<td style=\"width: 152.136%; height: 10px;\" width=\"540\"><span style=\"font-family: 'times new roman', times, serif; font-size: 12pt;\">Decorrelation audio object supports configurable number of input channels. <\/span><\/p>\n<ul>\n<li><span style=\"font-family: 'times new roman', times, serif; font-size: 12pt;\">Range:1 to 16<\/span><\/li>\n<li><span style=\"font-size: 12pt;\">Default: 2<\/span><\/li>\n<\/ul>\n<p><span style=\"font-family: 'times new roman', times, serif; font-size: 12pt;\">The Decorrelation audio object supports the same number of output channels as the number of input channels.<\/span><\/td>\n<\/tr>\n<tr style=\"height: 10px;\">\n<td style=\"width: 19.386%; height: 10px;\" width=\"132\"><span style=\"font-family: 'times new roman', times, serif; font-size: 12pt;\"><strong>Number of non-zero elements<\/strong><\/span><\/td>\n<td style=\"width: 152.136%; height: 10px;\" width=\"540\"><span style=\"font-family: 'times new roman', times, serif; font-size: 12pt;\">The Decorrelation audio object supports the number of non zero elements, to store position and gain values, ranging from 1 to 64 and 1 being the default..<\/span><\/td>\n<\/tr>\n<tr style=\"height: 26px;\">\n<td class=\"mtr-td-tag\" style=\"width: 19.386%; height: 26px;\" data-mtr-content=\"Properties\">\n<div class=\"mtr-cell-content\"><span style=\"font-size: 12pt; font-family: 'times new roman', times, serif;\"><strong>Display Name<\/strong><\/span><\/div>\n<\/td>\n<td class=\"mtr-td-tag\" style=\"width: 152.136%; height: 26px;\" data-mtr-content=\"Description\">\n<div class=\"mtr-cell-content\"><span style=\"font-size: 12pt; font-family: 'times new roman', times, serif;\">Display name of the Decorrelation audio object in signal flow design.
