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

This abstract first appeared for US patent application 20240249733 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 representing a different time or frequency resolution. An entropy encoder is used to encode the current coefficient based on the coding context to obtain an encoded audio stream.

• Processor derives coding context for currently encoded coefficient based on previously encoded coefficient
• Entropy encoder used to encode current coefficient based on coding context
• Segments of coefficients represent different time or frequency resolutions of audio signal
• Encoder encodes audio stream efficiently
• Innovation lies in the efficient encoding of audio segments

Potential Applications: - Audio compression technology - Streaming services - Digital audio processing

Problems Solved: - Efficient encoding of audio segments - Reduction of data size in audio streaming

Benefits: - Improved audio compression - Enhanced streaming performance - Reduced data storage requirements

Commercial Applications: Title: Advanced Audio Compression Technology for Streaming Services This technology can be utilized in various commercial applications such as online music platforms, video streaming services, and telecommunications companies to enhance audio quality and reduce bandwidth usage.

Questions about Audio Encoding Technology: 1. How does the processor derive coding context for the currently encoded coefficient? The processor uses information from a previously encoded coefficient representing a different time or frequency resolution to determine the coding context for the current coefficient.

2. What is the role of the entropy encoder in the audio encoding process? The entropy encoder is responsible for encoding the current coefficient based on the derived coding context to obtain an encoded audio stream.

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 entropy encoding the current coefficient based on the coding context to obtain an encoded audio stream.
