After the booming success of Google’s Chromecast, the internet giant have started working on Cast For Audio, an audio-only version of system that streams audio to certified speakers. The first speakers supporting this technology should reach the market in Spring 2015.
Cast for Audio uses the same simple interface as Chromecast. Press the ‘Cast’ button and the device sends over the audio to the speaker. From there, the speaker pulls that music directly from the internet, thus giving the user the ability to do anything else on the device too. Cast for Audio will be competition for AirPlay and Bluetooth speakers, but the fact that Google’s technology pulls the music from the cloud gives it an edge over the others. Audio selection and volume is still controlled by the device over WiFi, just like ChromeCast.
