Transform Encoding/Decoding of Harmonic Audio Signals - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240321283 titled 'Transform Encoding/Decoding of Harmonic Audio Signals
The abstract describes an encoder for encoding frequency transform coefficients of a harmonic audio signal, which includes a peak locator, a peak region encoder, a low-frequency set encoder, and a noise-floor gain encoder.
- The peak locator is designed to find spectral peaks with magnitudes exceeding a predetermined threshold.
- The peak region encoder encodes peak regions surrounding the located peaks.
- The low-frequency set encoder encodes coefficients outside the peak regions and below a crossover frequency based on the number of bits used for encoding peak regions.
- The noise-floor gain encoder encodes the noise-floor gain of high-frequency coefficients outside the peak regions.
Potential Applications: - Audio signal processing - Music production - Speech recognition technology
Problems Solved: - Efficient encoding of frequency transform coefficients - Improved audio signal quality - Reduction of data size in audio processing
Benefits: - Enhanced audio signal representation - Reduced storage requirements - Improved signal-to-noise ratio
Commercial Applications: Title: Advanced Audio Signal Encoding Technology This technology can be used in various industries such as telecommunications, entertainment, and broadcasting for efficient audio signal processing, leading to improved quality and reduced data size.
Prior Art: Researchers can explore prior patents related to audio signal processing, frequency transform encoding, and noise reduction techniques to understand the existing technology landscape.
Frequently Updated Research: Researchers in the field of audio signal processing and data compression may be conducting studies on advanced encoding techniques for improved efficiency and quality in audio processing.
Questions about Audio Signal Encoding Technology: 1. How does the encoder determine the crossover frequency for encoding low-frequency coefficients? 2. What are the potential implications of this technology for real-time audio processing applications?
Original Abstract Submitted
an encoder for encoding frequency transform coefficients of a harmonic audio signal include the following elements: a peak locator configured to locate spectral peaks having magnitudes exceeding a predetermined frequency dependent threshold. a peak region encoder configured to encode peak regions including and surrounding the located peaks. a low-frequency set encoder configured to encode at least one low-frequency set of coefficients outside the peak regions and below a crossover frequency that depends on the number of bits used to encode the peak regions. a noise-floor gain encoder configured to encode a noise-floor gain of at least one high-frequency set of not yet encoded coefficients outside the peak regions.
