Whereas earlier versions of my C64 music emulator had been Flash based, this marks the transition to HTML5/WebAudio.
Here a link to a youtube recording in case your browser doesn’t meet the technical requirements of the online version: https://www.youtube.com/watch?v=nLILmz52LH4
update: I occasionally still make improvements to the emulation, e.g. configurations not limited to 3 SID chips and respective stereo support: https://www.wothke.ch/websid_stereo/ or manual filter tuning: https://www.wothke.ch/websid_filter/
