Abstract

A soft decision audio decoding system for preserving audio continuity in a digital wireless audio receiver is provided that deduces the likelihood of errors in a received digital signal, based on generated hard bits and soft bits. The soft bits may be utilized by a soft audio decoder to determine whether the digital signal should be decoded or muted. The soft bits may be generated based on the detected point and a detected noise power, or by using a soft-output Viterbi algorithm. The value of the soft bits may indicate confidence in the strength of the hard bit generation. The soft decision audio decoding system may infer errors and decode perceptually acceptable audio without requiring error detection, as in conventional systems, as well as have low latency and improved granularity.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Patent Application Serial No. 14 / 844,632, filed September 3, 2015, the contents of which are hereby incorporated by reference in their entirety. technical field [0003] The present application generally relates to a soft decision audio decoding system. In particular, the application relates to a soft-decision audio decoding system that preserves audio continuity in digital wireless audio receivers with low latency and improved granularity by extrapolating the likelihood of errors in received digital signals . Background technique [0004] Audio products can involve the use of many components including microphones, wireless audio transmitters, wireless audio receivers, recorders and / or mixers to capture, record and present the sound of a product, such as television programs, news broadcasts, movies, live Events and other types of products. Microphones typically capture prod...
