Steps How Google Recognizes a Song
We can use Google Search app or the Google Assistant on any Android phone to search
or recognizing a certain Song. Over Google Assistant there is “What’s this song?”
suggestion pops up. Google search uses Now Playing to search an individual song.
The process described below:
- Data Acquisition:
Now playing records couple seconds to obtain sample data for testing.
Obtaining 10 seconds and eliminating all high pitch and irrational noises.
- Feature Extraction:
Collecting and extrapolating data from nodes to nodes to analyze and store
different wave lengths as multiple sample.
Classify analyzed data to a recognizable format to match with database
Now playing then searches the on-device song database to relate with the
classified information about the recorded sound.
After matching with multiple resources from database it sends a confirmation
report with the song’s name to the user.
