You may have noticed the flood of podcasts that’s been pouring out of the BBC since the launch of its BBC Sounds app. This is supposed to give us easier access to the programme archive but actually has been an excuse to show off the podcasts now made by the corporation, from the specially made How to be a Muslim Woman to Turbulence, a clever series of linked short stories by David Szalay, which was commissioned by Radio 4 and released as a podcast at the same time as being broadcast on the network.
