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

This abstract first appeared for US patent application 20240249735 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
• Encoded audio stream is obtained through the encoding process
• Innovation lies in the efficient encoding of audio segments based on contextual information

Potential Applications: - Audio compression technologies - Streaming services - Digital audio processing applications

Problems Solved: - Efficient encoding of audio segments with varying resolutions - Improved compression techniques for audio data

Benefits: - Reduced file sizes for audio data - Enhanced audio streaming capabilities - Improved audio processing efficiency

Commercial Applications: Title: Advanced Audio Encoding Technology for Enhanced Compression This technology can be utilized in various commercial applications such as: - Music streaming services - Audio editing software - Online gaming platforms

Questions about Audio Encoding Technology: 1. How does the audio encoder determine the coding context for each coefficient? The processor derives the coding context based on the previously encoded coefficient representing a different time or frequency resolution. 2. What are the potential advantages of using this audio encoding technology in streaming services? This technology can lead to faster streaming speeds and reduced bandwidth usage, enhancing the overall user experience.

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.
