The Home Recording Show
A Californian and a Canadian are the hosts, most of the time, discussing recording techniques and other audio "how-to's." They also discuss listener's comments, so you can throw in your two cents, and maybe they'll talk about it in their next show.http://www.homerecordingshow.com/
A show based out of the UK where a collection of industry professionals get together and talk about audio news and technology, as well as song production. You can actually watch them streaming live as they record the podcast every Wednesday.http://www.sonicstate.com/sonictalk
Both podcasts are available on iTunes and share a wealth of information and release new episodes frequently. Both put a new episode out yesterday, so check them out and get your audio fix for the hour.
