METHODS FOR PHASE ECU F0 INTERPOLATION SPLIT AND RELATED CONTROLLER - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240304192 titled 'METHODS FOR PHASE ECU F0 INTERPOLATION SPLIT AND RELATED CONTROLLER

Simplified Explanation:

This patent application describes a method for controlling a concealment technique for a lost audio frame in a received audio signal. The method involves obtaining at least one bin vector from a spectral representation for at least one tone, determining whether the bin values in the vector are complex or real, and processing the values to estimate the frequency of the tone based on their nature.

  • The method involves obtaining bin vectors with three consecutive bin values for tones.
  • It determines if each bin value is complex or real.
  • The values are then processed to estimate the frequency of the tone based on their nature.

Key Features and Innovation:

  • Concealment method for lost audio frames in received signals.
  • Analysis of bin vectors to determine tone frequency.
  • Processing of bin values based on their complex or real nature.

Potential Applications:

  • Audio signal processing.
  • Error concealment in audio transmission.
  • Frequency estimation in audio signals.

Problems Solved:

  • Addressing lost audio frames in received signals.
  • Improving accuracy of tone frequency estimation.
  • Enhancing audio signal quality.

Benefits:

  • Improved audio signal reconstruction.
  • Enhanced audio playback experience.
  • Better error correction in audio transmission.

Commercial Applications:

  • Audio equipment manufacturing.
  • Telecommunication industry for audio transmission.
  • Multimedia applications for audio processing.

Questions about the Technology:

1. How does this method improve the accuracy of frequency estimation in audio signals? 2. What are the potential implications of this technology in the field of audio signal processing?

Frequently Updated Research:

Stay updated on advancements in audio signal processing techniques for improved error concealment and frequency estimation.


Original Abstract Submitted

controlling a concealment method for a lost audio frame associated with a received audio signal is provided. at least one bin vector of a spectral representation for at least one tone is obtained, wherein the at least one bin vector includes three consecutive bin values for the at least one tone. whether each of the three consecutive bin values has a complex value or a real value is determined. responsive to the determination, the three consecutive bin values are processed to estimate a frequency of the at least one tone based on whether each bin value has a complex value or a real value.
