METHODS AND APPARATUS TO EXTRACT A PITCH-INDEPENDENT TIMBRE ATTRIBUTE FROM A MEDIA SIGNAL - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240331669 titled 'METHODS AND APPARATUS TO EXTRACT A PITCH-INDEPENDENT TIMBRE ATTRIBUTE FROM A MEDIA SIGNAL
The patent application describes methods and apparatus for extracting a pitch-independent timbre attribute from a media signal.
- An audio characteristic extractor determines a logarithmic spectrum of an audio signal.
- The logarithmic spectrum is transformed into a frequency domain to generate a transform output.
- The magnitude of the transform output is determined.
- A timbre attribute of the audio signal is determined based on an inverse transform of the magnitude.
Potential Applications: - Music production and audio engineering - Speech recognition technology - Sound analysis and classification systems
Problems Solved: - Extracting timbre attributes independent of pitch - Enhancing audio signal processing accuracy
Benefits: - Improved audio analysis and classification - Enhanced sound quality in various applications
Commercial Applications: Title: Advanced Audio Analysis Technology for Enhanced Sound Processing This technology can be utilized in music production software, speech recognition systems, and audio editing tools to improve the quality and accuracy of sound processing.
Questions about the technology: 1. How does this technology improve audio signal processing accuracy?
- This technology utilizes a logarithmic spectrum and frequency domain transformation to extract timbre attributes, enhancing the accuracy of sound analysis.
2. What are the potential applications of this technology beyond music production?
- This technology can also be applied in speech recognition technology and sound classification systems for various industries.
Original Abstract Submitted
methods and apparatus to extract a pitch-independent timbre attribute from a media signal are disclosed. an example apparatus includes an audio characteristic extractor to determine a logarithmic spectrum of an audio signal; transform the logarithmic spectrum of the audio signal into a frequency domain to generate a transform output; determine a magnitude of the transform output; and determine a timbre attribute of the audio signal based on an inverse transform of the magnitude.
