POST-PROCESSOR, PRE-PROCESSOR, AUDIO ENCODER, AUDIO DECODER AND RELATED METHODS FOR ENHANCING TRANSIENT PROCESSING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240347067 titled 'POST-PROCESSOR, PRE-PROCESSOR, AUDIO ENCODER, AUDIO DECODER AND RELATED METHODS FOR ENHANCING TRANSIENT PROCESSING
The abstract describes an audio post-processor for processing an audio signal with time-variable high frequency gain information.
- Band extractor separates high and low frequency bands of the audio signal.
- High band processor modifies the high frequency band based on time-variable gain information.
- Combiner combines the processed high frequency band with the low frequency band.
- Pre-processor is also included in the system.
Potential Applications: - Audio enhancement in music production - Noise reduction in audio recordings - Voice processing in telecommunications
Problems Solved: - Improving audio quality by adjusting high frequency gain dynamically - Enhancing clarity and detail in audio signals
Benefits: - Enhanced audio quality - Customizable high frequency gain adjustments - Improved overall listening experience
Commercial Applications: Title: Dynamic Audio Processing Technology for Enhanced Sound Quality This technology can be used in audio equipment manufacturing, music production studios, telecommunications companies, and entertainment venues to improve audio quality and user experience.
Questions about the technology: 1. How does the time-variable high frequency gain information improve audio processing?
- The time-variable gain information allows for dynamic adjustments to the high frequency band, enhancing audio quality.
2. What are the potential drawbacks of using a post-processor with time-variable gain information?
- One potential drawback could be increased complexity in audio processing algorithms, leading to higher computational requirements.
Original Abstract Submitted
an audio post-processor for post-processing an audio signal having a time-variable high frequency gain information as side information includes: a band extractor for extracting a high frequency band of the audio signal and a low frequency band of the audio signal; a high band processor for performing a time-variable modification of the high frequency band in accordance with the time-variable high frequency gain information to obtain a processed high frequency band; and a combiner for combining the processed high frequency band and the low frequency band. furthermore, a pre-processor is illustrated.
