Rdio upgrades entire catalog to AAC and 320kbs streaming

Rdio has converted its entire music library to AAC format, offering up to 320kbps streaming across web, Android and iOS apps. Previously, Rdio offered 96kbps MP3 streaming as default. Now, Rdio users can now choose between streaming bitrates of 64kbps, 96kbps and 192kbps in the settings menu, with 320kbps only available to Rdio Unlimited subscribers. […] AAC is generally more data efficient — an advantage for mobile streaming — and offers better sound quality than MP3 streaming at lower bitrates. – Lexy Savvides,CNET
