For a book published in 2005, it is actually quite useful and has a bunch of applicable information even now in 2018. Podcasting Solutions is one of a stack of books a co-worker let me borrow for a work project, and I was surprised by how much I have used it.

What this volume excels at is providing an intuitive, in-depth technical walk-through of recording equipment, the recording process, the audio editing process, and setting up a RSS feed. It uses images well to convey 'scientific' ideas and explanations. Perhaps my only critique is that the flow is a bit dry, and while I enjoyed its direct and technical way of communicating processes, I can understand how that could be unappealing to others.

Overall, if you have a need to learn more about the technical side to podcasting, this is a solid how-to book.
