Abstract

In various embodiments, a platform is provided for interactive user experiences. An application, running on device A, can be synchronised with the audio reproduced by a device B. Device A can listen to the audio of device B and obtaining the timecode by processing the recorded audio. Therefore, an application, running on a portable device, can display trivia and information exactly at certain points of a show reproduced by a TV set located in the same room.

Claims

1. A method for providing an interactive user experience, the method comprising:

receiving, at one or more computer systems, a first signal recorded or sampled from a target signal;

determining, with one or more processors associated with the one or more computer systems, a reference signal based on the first signal;

determining, with the one or more processors associated with the one or more computer systems, a correlation between the first signal and the reference signal; and

generating, with the one or more processors associated with, the one or more computer systems, synchronization information between presentation of the target information and presentation of a second signal.

2. A method for non-invasive accurate audio correlation as described above.

3. A non-transitory computer-readable medium storing processor-executable code for directing a processor to perform non-Invasive accurate audio correlation as described above.

4. A handheld device having at least a microphone, a display, a processor, and a memory wherein the memory is configured to store a set of instructions which direct the processor to capture audio from an audio source using the microphone and synchronize playback of content on the display to playback of audio at the audio source.
