USING STRUCTURED AUDIO OUTPUT TO DETECT PLAYBACK AND/OR TO ADAPT TO MISALIGNED PLAYBACK IN WIRELESS SPEAKERS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18233369 titled 'USING STRUCTURED AUDIO OUTPUT TO DETECT PLAYBACK AND/OR TO ADAPT TO MISALIGNED PLAYBACK IN WIRELESS SPEAKERS
Simplified Explanation
This patent application describes a method for determining audio delay in a computing device.
- The audio delay is determined by transmitting an audio data stream wirelessly to the computing device and comparing the rendered audio output with the original audio data stream.
- A delay audio segment can be added to an additional audio data stream based on the determined audio delay.
- A noise reduction technique can be adjusted based on the audio delay.
- The patent application also discusses a method for determining if an audio data stream is actually being rendered by the computing device.
Original Abstract Submitted
Implementations are directed to determining an audio delay, of a computing device, by causing an audio data stream to be transmitted to the computing device via a wireless communication channel. The computing device causes audio output generated using the audio data stream to be rendered via speaker(s). The rendered audio output is captured via microphone(s), and the audio delay determined by comparing the captured audio output with the audio data stream. A delay audio segment can be appended to an additional audio data stream transmitted to the computing device, where the length of the delay audio segment is determined using the audio delay. A noise reduction technique can additionally or alternatively be adapted based on the audio delay. Implementations are additionally or alternatively directed to determining if an audio data stream transmitted to a computing device for rendering through speaker(s) driven by the computing device—is actually being rendered.
