The whole precedure: switch-on-klick. Heats up. Hisses with a few nice whistling melodies (from 00:27 on). Boils. Automatic switch off. Close stereo recording (10cm) with sony pcm-10. Pretty low background noise (kitchen ambience).
Electric shock sound effect created from various recorded electric sounds. There is a welding torch, jacobs ladder, transformer, and a few other sounds mixed.
The sound is composed with four partials,each partial includes a number of different harmonics,similar to additive synthesis. I am using yamaha moxf 6.
