ADVANCED SPEECH ENHANCEMENT SYSTEM AND A METHOD PERFORMING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240274146 titled 'ADVANCED SPEECH ENHANCEMENT SYSTEM AND A METHOD PERFORMING THE SAME
The method described in the abstract involves processing audio signals to reduce background noise and improve signal quality.
- Receiving a first audio signal with background noise and a second audio signal with reduced signal level from the first signal.
- Detecting level differences between the first and second audio signals in predetermined frequency bands.
- Estimating the signal-to-noise ratio (SNR) of the second audio signal in each frequency band based on the detected level differences.
- Adjusting the mixing ratio of the first and second audio signals independently for each frequency band to achieve a balanced SNR throughout.
Potential Applications: - Audio enhancement in noisy environments - Speech recognition systems - Music production and mixing
Problems Solved: - Improving audio quality in the presence of background noise - Enhancing the clarity of audio signals for various applications
Benefits: - Enhanced audio quality - Improved signal-to-noise ratio - Better performance of audio processing systems
Commercial Applications: Title: Advanced Audio Signal Processing Technology for Noise Reduction This technology can be used in: - Consumer electronics such as smartphones, headphones, and smart speakers - Professional audio equipment for recording studios and live sound applications - Communication systems for clearer voice transmission
Questions about the technology: 1. How does this method compare to traditional noise reduction techniques?
- This method offers more precise control over the mixing ratio for different frequency bands, resulting in a more balanced SNR.
2. Can this technology be integrated into existing audio processing software?
- Yes, this technology can be implemented as a software algorithm in various audio processing applications.
Original Abstract Submitted
a method for processing audio signals is presented, wherein the method includes receiving a first audio signal including a background noise; receiving a second audio signal with a reduced signal level from the first audio signal; detecting a level difference between the first audio signal and the second audio signal in each of a plurality of predetermined frequency bands; estimating a signal-to-noise ratio (snr) of the second audio signal for each of the plurality of frequency bands based on the detected level difference; and adjusting a mixing ratio of the first audio signal to the second audio signal based on the estimated snr independently for each of the plurality of frequency bands to generate an output audio signal having a balanced snr throughout the plurality of frequency bands.
