We are a commercial podcasting studio. Editing, engineering and mastering podcasts for our clients is our bread and butter. That means what I'm about to say has a clear bias inherit in it but I hope you will take it seriously because it is offered honestly and with your best interests in mind.
You are not an audio engineer. You will (probably) never be an audio engineer. You (probably) have no interest in becoming an audio engineer. You will (undoubtedly) need to pretend to be an audio engineer in the beginning - and that is because you won't have the money to hire one. Please believe me when I tell you that every minute you give to struggling to become a mediocre audio engineer is a minute lost for being an incredible podcast producer.
You are a producer. You know your content, you know the vision, you know your brand. This is your baby. Do not get in the way of your baby growing into a fully functional adult by insisting you be responsible for every aspect of its upbringing.
You send your kid to school because you need to work during the day to make money and because you can't teach them math and science and English.
If you quit your job and tried to teach them math, science, and English yourself, you'd make less money and your kids wouldn't get as good an education as they may have otherwise received.
This isn't (obviously) a swipe at homeschooling, it's an analogy to help you see that what you're good at is vision and content creation and that you should put all your time into what you're good at. Let someone who is good at audio engineering do your audio engineering. In short: know your role and commit fully to that role the moment you can afford to give the engineering role to someone else.
In this section we're going to talk about Digital Audio Workstations, or DAWs
Back in the day, recording studios used to be chalk full of all manner of equipment. Huge interfaces, mounted in wooden or metal racks with wires running all over the place. These days, however, much have this equipment has been virtualized into VST plugins, that's "Virtual Studio Technology". With the technology virtualized, you'll need some sort of virtual way to interact with it, right? And so we have the Digital Audio Workstation: a piece of software that allows us to capture audio, save it, edit it, engineer it, master it, and, ultimately, birth it into the real world through the headphones and speakers of millions.
There are many DAWs, we will discuss only two, because they are the best (for podcasting) and there's no need to discuss the others (in our opinion).
