AUDIO ENCODER AND AUDIO DECODER - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240249734 titled 'AUDIO ENCODER AND AUDIO DECODER

The abstract describes an audio encoder that encodes segments of coefficients representing different time or frequency resolutions of a sampled audio signal. The encoder includes a processor that derives a coding context for a currently encoded coefficient based on a previously encoded coefficient of a different resolution. An entropy encoder is used to encode the current coefficient based on the coding context to generate an encoded audio stream.

• Processor derives coding context for currently encoded coefficient based on previously encoded coefficient of different resolution
• Entropy encoder encodes current coefficient based on coding context
• Segments of coefficients represent different time or frequency resolutions of audio signal
• Audio encoder generates encoded audio stream
• Innovation focuses on efficient encoding of audio signals with varying resolutions

Potential Applications: - Audio compression algorithms - Streaming audio services - Voice recognition systems

Questions about Audio Encoding Technology: 1. How does the audio encoder handle different resolutions of coefficients in the encoding process? The audio encoder uses a processor to derive coding contexts for coefficients of varying resolutions, ensuring efficient encoding. 2. What advantages does the entropy encoder provide in the encoding of audio signals? The entropy encoder helps in encoding the current coefficient based on the coding context, leading to a more compact and efficient representation of the audio data.

Original Abstract Submitted

an audio encoder for encoding segments of coefficients, the segments of coefficients representing different time or frequency resolutions of a sampled audio signal, the audio encoder including a processor for deriving a coding context for a currently encoded coefficient of a current segment based on a previously encoded coefficient of a previous segment, the previously encoded coefficient representing a different time or frequency resolution than the currently encoded coefficient. the audio encoder further includes an entropy encoder for encoding entropy the current coefficient based on the coding context to obtain an encoded audio stream.
