We know and understand HE-AAC technology from our vast experience with both encoder and decoder software deployed at millions of locations around the world. We are destined to improve Internet audio quality and change the way Internet audio is perceived and consumed.

Streams HiFi improvements

I like the updated version of this app. Lower loading times easier to access the map and it seems to support all the native codecs in the Apple OS. The main screen has a faster load time and larger icons. Good value for the money. Five stars.

This app is awesome.

I’ve own this app for over 10 years. It’s one of the best. It’s my goto music app for live radio. Great audio quality and very reliable. It works really well with CarPlay and Siri, the best so far.
