Audio Encoder, Audio Decoder and Related Methods Using Two-Channel Processing Within an Intelligent Gap-Filling Frame

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a technology for encoding and decoding two-channel (stereo) audio signals using intelligent gap-filling techniques in the frequency domain. It involves analyzing portions of the audio spectrum, extracting and using parameters to regenerate missing or incomplete audio segments, and improves stereo audio processing efficiency.

Use CasesContent extracted from patent full text and abstract with AI.

• High-quality music streaming services requiring efficient stereo audio compression and decompression
• Audio playback in devices with limited bandwidth or storage, such as mobile phones or portable players
• Live audio broadcasting where audio data losses might occur and need to be recovered
• Hearing aids or assistive listening devices that process stereo sound efficiently
• Video conference systems or VoIP solutions needing robust, bandwidth-efficient stereo sound

BenefitsContent extracted from patent full text and abstract with AI.

• Reduces the amount of data needed to transmit or store stereo audio signals without significant loss in quality
• Restores or fills gaps in audio data effectively, improving robustness to data transmission errors or losses
• Delivers more efficient audio compression, resulting in lower storage and bandwidth requirements
• Maintains high audio quality despite audio losses or gaps, enhancing user experience
• Flexible and applicable to a variety of stereo audio processing scenarios
