Apple has released new software it is making exclusively available to .Mac subscribers – the .Mac Podcast Pack.

The software consists of a range of professional music jingles and voiceovers, which have been released as a series of loops for use within GaragBand-generated podcast projects.

Ten packs are available, ranging between 35.2MB and 119.9MB in size. These include jingles in Alternative Rock; Blues; Cinematic; Country; Electronic; Jazz; Rock and pop; Urban; and World music styles.

The tenth pack – Voice Over – features the "professional voice talent of Joe Cipriano to give your podcast extra polish," the company states on its .Mac pages.

Full instructions for using the packs and for the creation and distribution of podcasts through .Mac are also available.
