Google Sound Search is coming to Google Glass
After the latest Google Glass software update XE6 there is a hint in the code that Google Glass will have a built-in app for recognizing music (like shazam does). The option SOUND_SEARCH is only available on engineering or userdebug builds and is disabled by default. A github user zhuowei who is constantly researching hidden features in the code activated this feature and had his moment of success when he installed the google glass code on a Nexus 7:
I tried holding it to headphones playing “Fireflies” and it recognized it.
After activation the feature you just say “OK Glass, Google” and swipe right
What is Google Sound Search for Google Play?
The Google Play Sound Search widget can help you recognize music and songs playing around you. You can:
-Identify songs, directly from your homescreen
-Purchase identified songs straight from Google Play, and add them to your Play Music library
-Keep a song identification history, synced across all of your Android devices, so you can purchase a song later
-Add the widget directly to your lockscreen, so you can recognize songs even faster (for devices running Android 4.2)
After you’ve installed the Google Play Sound Search widget, go to the widget picker and drag the Sound Search widget onto your homescreen. Click on the widget to start recognizing.
