After you finish recording your show, you will be left with an Mp3 file, that can be used by itself for the podcast, but may require some trimming, or augmenting. There are 2 programs I use for this business, and they are both free to try- but there is no limit on how many times you reinstall and "try" again. They are NCH Software's Wavepad and Mixpad. Wavepad is a single file sound editor, and is great for trimming the start and end of a show, cutting out of bleeping any unnecessary content, and making any audio adjustments. Mixpad is a multi-track audio mixing software, and is useful for Adding intro music, putting seperate files together, etc. Combined, these two applications make quick work of what could be a tedious editing process. Once you finish editing your show, save the file as an Mp3, 128kps is good quality, but if you want a smaller file go 64kps. After this has saved, open the properties of the Mp3 and modify to the metadata to reflect the title, and type of file among other things. Its important to label the show as a podcast within the metadata, or else it might get lost among music Mp3s.
