And now onto the full ad reads. As always, no ads in the middle. I try to make these interesting, but if you must skip them, friends, please do check out our sponsors. I enjoy their stuff. Maybe you will too. This episode is also brought to you by Riverside, the platform for recording remote podcasts in studio quality. I've used them a bunch of times in the past. They're amazing.
It is the thing I recommend for anybody, especially for people starting a podcast. Studio quality, exceptionally easy to use. A million features that are all extremely useful for the whole... pipeline of creating a podcast, I mean, where do I start? First of all, they do the editing. And you could do text-based editing of the audio and the video.
So whatever you say, there's an AI-generated transcript in like 100 plus languages, whatever the language is, you can use then the text to do the editing. It does speaker detection, so it figures out who's speaking. All the synchronization obviously is done, not obviously, because some things seem obvious, but a really effortless, beautiful execution of it just is a breath of fresh air.
So, in case you don't know, it's through the browser, you record the video and the audio, both sides of the conversation, everything is synchronized, everything is stored, just everything is done really well. They have a lot of recommendations of what kind of hardware to use. I think in the video they provide, they say the most important thing is the microphone and lighting, and I agree with that.
Good audio is number one. Second to that is indeed lighting because basically every kind of camera that's available now will do all right. Anyway, Riverside makes that whole process super easy. I record my remote interviews with Riverside. Give it a try at Riverside.fm and use code Lex for 30% off. That's Riverside.fm and use code Lex.
This episode is also brought to you by ZipRecruiter, a site that connects employers and job seekers. To me, one of the most fulfilling things in life is working together with a great team. I love working. I love what I do. Everywhere I've ever worked, I loved doing it. And I love to be surrounded by people who also love doing it.
especially who are very good at it and are pushing themselves to the limit and together we're creating something special, whatever that is. It could be a small thing or it can be a world-changing thing. Whether the mission is small or the mission is big, as long as there's a mission and we're in it together and we're constantly improving.
