Noise Sweeps

Click here for audio

I’ve been deep in hardware development for quite a while now, so the blog and my responsiveness to e-mails have suffered. The good news is that something new is almost ready to show. This audio clip comes from a POKEY engine running inside an FPGA. The sweeping is the sound of modulating the POKEY clock across several octaves. I’m also varying the pitch in the registers of the POKEY engine, which is what causes the sudden changes in timbre.
