Lullaby #2 - FFT Grain Meditation
By kevanatkins on February 21, 2016 8:35 pm
Following on from last week... It's a looping granular texture generated from a small sample from a recorded improv. As the piece progresses the pitch is modulated very slowly with an increasing amplitude using a FFT-based pitch shift. Although the pitch material is the same relatively, the shifts across a four octave range effectively emphasise different pitches in the loop depending non-linearities in sound reproduction and perception.
