It was always a matter of time, but now Alexa has the ability to turn Echo devices into multi-room speakers that many owners have long been clamoring for. Starting today, the feature is available for Amazon Music, TuneIn, iHeartRadio, and Pandora, while support for Spotify and SiriusXM is said to be "coming soon." This so far only applies to users in the US, UK, and Germany.Any combination of Echos, Echo Dots, and Echo Shows can be used in a multi-room setup. You'll need to use the Alexa app to create groups, which you then name to allow Alexa to recognize them. For example, you could have a 'downstairs' group and an 'upstairs' group. Then you can simply ask Alexa to "play John Mayer downstairs." Unfortunately, it seems as though the same device can't be part of more than one group at the same time, which will be a disappointment for many (Thanks to Tiuri Elvander for pointing that out).At the same time, Amazon has announced two new sets of tools for developers. The first is the Alexa Voice Service (AVS) Multi-Room Music SDK which will allow any AVS enabled speaker to be linked to Echo devices as part of a multi-room speaker system. This won't be available until next year, however.A Connected Speaker API developer preview was also introduced, so that connected audio systems can also be controlled via Alexa. Amazon is working with brands such as Sonos, Bose, and Samsung to get their devices up and running with AVS. You can find out more information about both sets of new tools on the Amazon Developer site.Source: Amazon
