The First Sounds

Posted: February 3, 2016 at 1:14 pm

While waiting for my 75,000 percept rendering to compute, I’ve returned to audio. I ended up saving the real and imaginary spectra separately, and this not dealing with any signal transformation. This is the first time I’ve heard the results and its quite striking how well it reproduces the quality of sounds (voice) without any of the specificity (words). In this case I used 1000 clusters, so 1000 sounds to represent 10,000 seconds of audio. I’m now running k-means again with 5000 clusters so that the sound could be more readable linguistically.

Audio reconstruction using 1000 clusters and 2000 bins.
