Analyze the clean up needed for your podcast. First, by spectrally identifying the noise removal/reduction process needed on the audio quality. Second mix the audio tracks (if there are two tracks) in multitrack. Then we would edit it by removing loud breaths, ahms, uhm, ahhh, long pauses, repetitive words, distorted sounds, clicks, pops and other unnecessary elements in the podcast. Enhancement then follows by analyzing the compression, limiting and mastering that your podcast need to achieve the best audio quality for broadcast.
