From Bjoern Hassler

Editing is a relatively laborious process. You will have to go through your audio, bit by bit, and remove each section of audio that is irrelevant or unnecessary. It is slow, but worth it. In conversation, even lectures, we often jump off topic or simply pause while we speak. While fine in conversational speech, podcasts are different because we want them to be relatively fast-paced and easy to follow. As such, we edit this audio out.

You might also wish to record an introduction or closing remarks for the podcast. Many sound editing software programs have features that allow you to record additional material directly into the computer and then attach this to the beginning or end of the larger recording. Some of the most successful podcasts have a standard introduction to an entire series, or will outline the contents of the podcast ("In today's podcast...").

2 A quick note about Dynamic range compression

Ever wondered why the recording sounds so quiet? Speech recordings naturally have a large dynamic range and you will have left enough head room to make sure you get a good recording. In the edit you need to remove the headroom (normalisation) and reduce the dynamic range to make the recording suitable for playback via laptop, radio, personal MP3 player. Unless you are planning to produce theatrical sound for cinema performances you need to apply dynamic range compression!
