Abstract
Various examples and techniques pertaining to audio output monitoring for failure detection of warning sound playback are described. In one aspect, audio data, which includes a plurality of bits of a first sound sample and one or more control bits for integrity check, is retrieved from a data storage. The audio data is processed by: (i) performing an integrity check on the first sound sample based on the one or more control bits, and (ii) playing back a first sound using the first sound sample. The first sound can be a warning sound in automobile applications.
Claims20
A method, comprising:
- retrieving first audio data from a data storage, the first audio data comprising a plurality of bits of a first sound sample and one or more control bits for integrity check;
- and
- processing the first audio data, the processing comprising:
- performing an integrity check on the first sound sample based on the one or more control bits;
- and
- playing back a first sound using the first sound sample.
An apparatus, comprising:
- a data storage storing first audio data and second audio data different from the first audio data, the first audio data comprising a plurality of bits of a first sound sample and one or more control bits for integrity check;
- and
- a circuit coupled to the data storage such that, during operation, the circuit performs operations comprising:
- retrieving the first audio data from the data storage;
- and
- processing the first audio data by:
- performing an integrity check on the first sound sample based on the one or more control bits;
- and
- playing back a first sound using the first sound sample.
