Embodiment Construction

[0023] The detailed description, set forth below in conjunction with the accompanying figures, is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details to provide a thorough understanding of various concepts. It will be apparent, however, to one skilled in the art that these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring the concepts.

[0024] Some aspects of audio error cancellation will now be presented with reference to various apparatus and methods. These devices and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as "elements"). The...

Abstract

A method, a computer readable medium, and an apparatus for audio error concealment are provided. The apparatus may receive a plurality of audio frames. The apparatus may receive a first audio frame after the receiving of the plurality of audio frames. The apparatus may detect a second audio frame being lost in transmission. The second audio frame is transmitted after the plurality of audio frames and before the first audio frame. The apparatus may identify an audio segment within the plurality of audio frames that best matches a reference audio pattern of the plurality of audio frames. The identified audio segment may be received before the last audio frame of the plurality of audio frames. The apparatus may reconstruct the second audio frame based on audio data received subsequent to the identified audio segment.

Description

technical field [0001] Aspects of this disclosure relate generally to signal processing, and more specifically to audio error cancellation. Background technique [0002] In digital wireless audio applications, ie wireless speakers or wireless headphones, audio data is packetized and sent in bursts from the transmitter to the receiver. In such digital wireless audio applications, a retry mechanism is used to improve the success rate of audio data transmission. However, audio data packets (also referred to as audio frames) may be lost if transmission fails after a certain number of retries. When there are gaps in the audio signal due to packet loss (ie, packet loss), the listener may hear skips or pops. [0003] figure 1 An example of audio signal gaps caused by packet loss is illustrated. In this example, the raw audio data transmitted by the transmitter is shown in diagram 100 . The audio packets received by the receiver are shown in diagram 120 . Packet 122 was lost d...
