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

This abstract first appeared for US patent application 20240249736 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 obtain an encoded audio stream.

• Processor derives coding context for currently encoded coefficient based on previously encoded coefficient of different resolution
• Entropy encoder used to encode current coefficient based on coding context
• Segments of coefficients represent different time or frequency resolutions of audio signal
• Aim is to efficiently encode audio data for transmission or storage
• Innovation lies in the adaptive coding context derivation based on previous coefficients

Potential Applications: - Audio streaming services - Digital audio broadcasting - Voice over IP applications

Problems Solved: - Efficient encoding of audio data - Improved compression of audio signals - Enhanced transmission and storage of audio content

Benefits: - Reduced bandwidth requirements - Improved audio quality - Enhanced storage efficiency

Commercial Applications: Title: "Advanced Audio Encoding Technology for Improved Data Compression" This technology can be utilized in various commercial applications such as online music streaming platforms, telecommunications companies for voice transmission, and audio recording equipment for improved data compression and storage efficiency.

Questions about Audio Encoding Technology: 1. How does the adaptive coding context derivation improve the efficiency of audio encoding? The adaptive coding context derivation allows for more accurate prediction of the current coefficient, leading to better compression and encoding efficiency.

2. What are the potential drawbacks of using entropy encoding in audio encoding? Entropy encoding can be computationally intensive, requiring more processing power, which may impact real-time encoding applications.

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.
