Why are audio and video analyzed in my browser?
Privacy and speed: large media files stay on your device.

Audio and video files are often large and personal. Analyzing them in your browser means they are never uploaded, and results appear faster.
Your browser reads the container (MP4, MOV, MP3, WAV, FLAC…) to extract codec, duration, bitrate and metadata, then decodes the audio and samples video frames to compute Level 2 indicators. Only an anonymous counter (content type and level) is sent to our server for statistics.
