Amanda Litherland speaks to two innovative audio makers.

Ross Sutherland reveals some of the thinking behind his puzzling new fiction podcast 'The Golden House' - a mini series from Imaginary Advice stuffed full of codes and secrets.

Later, the award winning documentary producer Cathy Fitzgerland discusses her latest project 'Witness' in association with Amnesty International - a podcast which skilfully tells sensitive stories from some of the world's darkest places. Cathy also speaks about how she came to work in audio, and shares her advice on creating great listening, such as Life On Lockdown for Radio 4.

Then Podcast Radio Hour producer Chris Pearson joins Amanda to go through a few of your recommendations for innovative podcasts, including Giant, The Friendship File Podcast, and Totalus Rankium.
