Hello
i have asked this is a few different ways and experimented but i am wondering, how does one create "smooth random" numbers that flow between each number instead of hoping from number to number?
When trying to translate the settings of a 10 band graphic equalizer to a smooth spectrum I had a similar issue for which I used cubic interpolation in three steps. The first two steps involves factor 2 'upsampling' each, which renders a 40 point (+interpolation points) curve smooth enough for interpolation to 1024 points in one last step. Attached patch cubic_upsampling.pd shows the interpolation steps done on a sequence of random numbers.
