Whatever your show type, you’ll need to put some thought into editing.
The simplest method is to pay someone. You provide the audio and your editor assembles the elements and gives you the finished MP3.
For the DIY approach, GarageBand is a great place to start on the Mac. Newer versions aren’t optimised for podcast editing but they’ll still let you do the basics.
Audacity is free and works on Macs and PCs. It’s basic but lots of people use it, so there are plenty of guides online.
Hindenburg starts at under $100. It has tools like auto-levelling and one-click podcast uploading, and it runs on macOS and Windows.
Logic Pro X is Apple’s flagship audio software for the Mac. It’s full-featured and is what lots of pros use. At $200 it’s steeper than Hindenburg, but once you get to grips with it, you’ll likely never need to move.
And for both Mac and PC, there’s Adobe Audition. You can pick this up with a Creative Cloud subscription, but if it’s the only Adobe app you use, it might not be worth shelling out every month.
