Explained simply, a Podcast is an effective method of publishing recorded talk and music through the internet, in a way that will automatically tell your listeners when your new material is available.
Podcasts can be published either locally to your hard disk, to an iDisk on a .Mac account, or to a web site through an FTP server. It will manage your podcasts publishing and removing files when they are no longer required. It supports specific iTunes Music Store tags such as images, copyright notices, categories and links to web sites.
Podcaster will also create 'enhanced podcasts', these are audio files which contain chapter markers where you can include titles, images and web links.The images in these files can be viewed on an iPod with photo capabilities. Enhanced podcasts can be created from movies, an iMovie project and even from slideshows in iPhoto. Podcaster automatically extracts the audio content in the correct format, with a configurable bit rate to save disk space, and also resizes the images to the correct format. Podcaster is ideal for anyone wishing to create podcasts for broadcasting on the Internet.
