Google Cast built-in: Stream it all with WiFi

Everyone who has a smartphone or tablet carries around the means to access nearly every song ever made. Simply open an app like Deezer or Google Play Music and listen to your choice of music on a pair of headphones. But what about enjoying this music on other devices? Is there a way to transfer this near-endless selection from the cloud to a loudspeaker?

Google Cast built-in is a streaming technology developed by Google to make the music selections you enjoy with headphones available throughout the home. An incredibly flexible system, Google Cast built-in works with the Chrome browser and over 100 apps. A tap on your smartphone screen is all it takes to send music selections to your speakers. Read on to learn more about Google Cast built-in technology.

How Google Cast built-in works

Google Cast built-in works just like a Google Cast Ethernet adapter. The only difference is that Google Cast built-in technology is part of the device. No additional adapter or dongle is required. The Google Cast streaming technology uses standard home WiFi networks to send pictures, videos and audio files from a sender to a receiver. The sender can be a smartphone, tablet or PC. Receivers range from televisions to loudspeakers depending on the content. The precondition is that both the sender and the receiver use the same WiFi network and support the Google Cast streaming standard. Loudspeakers with Google Cast built-in only access audio content via the streaming technology.

What do you need to stream with Google Cast?

When it comes to implementing Google Cast, there are many different ways to go about it. Those who already have an active speaker system can make it Google Cast-enabled with an Audio Ethernet adapter. This is a small dongle that plugs the system, allowing it to stream from any Google Cast-enabled app. Unlike the video adapter which connects via HDMI input, Google Cast Audio connects to loudspeakers via standard 3.5 mm stereo or TOSLINK optical input.

Google Cast can also be added to a WiFi speaker’s operating software. Speakers with Google Cast built-in are able to receive audio from any Google Cast-enabled app without an additional dongle or adapter. This simple and direct ability to stream from apps is very much like Bluetooth. The key difference is that Google Cast streams via WiFi for a much larger range and better audio quality. As long as the control device — such as a smartphone, tablet or PC — is connected to the same WiFi network as the speakers with Google Cast built-in, the user can move freely about the home and control audio in any room. Simply open any Google Cast-enabled app, tap the Cast button and the music stream selected will play on any speaker with Google Cast built-in. WiFi streaming also requires very little energy from the control device which saves battery life.

Google Cast streams the following audio formats

Google’s streaming architecture supports a number of audio formats including AAC and MP3 as well as lossless formats like WAV and FLAC. Google Cast can also transmit the surround sound standards Dolby Digital and Dolby Digital Plus to an AV receiver for decoding and playback.

    Hi I have Teufel One S speaker which I bought 5 Years ago. I would like to know if it is possible to connect it with Chromecast use it for music. I know that I can connect it to Amazon assistant via cable but is it possible to use it only for music with Google assistant? Furthermore, if I buy a second One S will it be possible to connect them wirelessly? Thank you very much.

      Hi Nicolas. Unfortunately, that model is not compatible with Chromecast and Google assistant. You can however pair two One S units wirelessly. Hope that answers your question!

    I don’t quite understand why you have decided to downgrade the One S speakers without Chrome Cast build-in. Meanwhile my question is: will it be possible by purchasing a Crome Cast adapter to set up multi-room streaming from my music service (which is not Spotify)? And would it be possible to stream to a pair of One S speakers set up in stereo?
