This week on Tech Weekly with Aleks Krotoski we discuss the survival of the MP3, a legacy format created for the first generation of hard disc portable music players such as the iPod. Do people now want to hear music at higher resolutions? Gilad Tiefenbrun discusses his company Linn Music with tech reporter Samuel Gibbs and argues that Linn's high-res music-download store and Neil Young's planned Pono player are a sign of things to come for the digital download.

Also Aleks is joined by technology editor Charles Arthur and tech reporter Alex Hern to discuss Julian Assange's possible exit from the Ecuadorian embassy. What is the role of Assange and Wikileaks in a post-Edward Snowden world?

They also discuss Google's purchase of the clever travel-guide app Jetpac, and the return of Flappy Bird creator Doug Nguyen with the equally addictive Swing Copters.
