I got a chirp on the recordings, which was quite nasty since my voice - together with my screencast - is the only thing people get when the listen to my recordings. \n\nAs a long year reader of the great [c't Magazin](https://www.heise.de/ct/) I removed the power supply of my mac to see what happens. I didn't use the standard power supply, but in my setup I used the 349€ [Belkin Thunderbold 3 Pro dock](https://www.belkin.com/de/business/hubs-and-docks-for-business/docking-stations-for-business/thunderbolt-3-dock-pro/p/p-f4u097/), which I really loved since the old dream of using only one cable to connect my laptop to any device (USBs, Ethernet, power supply, external displays...) came true with it.\n\n\n### Second issue: power supply humming\n\nNow having disconnected the Belkin doc, my recording got rid of the chirping - but now there was a humming. After googling around I soon found a seamingly well known issue: [the magic hand issue](https://sendegate.de/t/macbook-pro-2016-netzbrummen-magische-hand-und-interface/4732/12). Because simply touching my MacBook the humming was gone. I could \"see\" that in OBS:\n\n![obs-with-humming](obs-with-humming.png)\n\nand touching my MacBook:\n\n![obs-after-touching-macbook](obs-after-touching-macbook.png)\n\nThis leads us to the root cause of the humming: no proper grounding! After a while of googling and thinkering it became clear to me. Current MacBooks don't ship with a grounded! TODAY! Having a look at the power supply this becomes obvious:\n\n![macbookpro-powersupply-2020](macbookpro-powersupply-2020.png)\n\nIn the detail view you see the 2 power supply conductors. And the bigger round grounding plug:\n\n![macbookpro-powersupply-2020-detail-grounding](macbookpro-powersupply-2020-detail-grounding.png)\n\n**But** looking a the plug there's only plastic inside!!\n\n![macbookpro-powersupply-2020-plug-without-grounding](macbookpro-powersupply-2020-plug-without-grounding.jpg)\n\nSo our MacBook Pro does not get grounded with the 2020/21 power supply setup.\n\nBut there's help! Many people suggest [to build your own cable](https://sendegate.de/t/bastelecke-erdungskabel-gegen-50hz-netzbrummen/3262) which is definitely possible, but not without risks for the non-electrically trained (like me). But I'm working with MacBooks since 2015 and luckily I have every cable right in my cellar - even the old extension cable from my MacBook Pro 2015! Let's have a detailled look onto it:\n\n![macbookpro-powersupply-extension-cable-2015](macbookpro-powersupply-extension-cable-2015.jpg)\n\nand especially the plugs:\n\n![macbookpro-powersupply-extension-cable-2015-plug](macbookpro-powersupply-extension-cable-2015-plug.jpg)\n\nThere's metal inside the power supply plug - and it's grounded into the socket! Using this cable together with my MacBook Pro 16'' power supply I got rid of the humming!\n\n\n### Third issue: a sublte humming\n\nAfter getting rid of the chirping and humming I started to get my first usable audio recordings. But there was a subtle humming left - not noticable on screen looking at OBS, but I heard it when using headphones and turining up the volume a bit more. But I also got rid of this last audio recording issue: I simply used [OBS' noice suppression option](https://obsproject.com/forum/threads/rauschunterdr%C3%BCckung.117913/). Therefore right click onto your microphone in OBS and click on `Filter`. There create a new filter from the `+` menu using `noise suppression` (or `Rauschunterdrückung` in german).","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjonashackt%2Faudio-podcast-macbook-setup","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjonashackt%2Faudio-podcast-macbook-setup","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjonashackt%2Faudio-podcast-macbook-setup/lists"}
