Title:
圧縮済みオーディオ信号の信号品質ベース強調及び補償
Document Type and Number:
Japanese Patent JP6576934
Kind Code:
B2
Abstract:
A sampler module may divide an audio signal into a series of sequential samples. A signal quality detector module may identify a consistent brick wall frequency of the audio signal spanning a plurality of the sequential samples at an outset of the audio signal and determine a signal treatment indication proportional to the brick wall frequency. A signal enhancer module may sequentially receive and analyze one or more sample components of the audio signal to identify lost parts of the audio signal in the one or more sample components of respective sequential samples, and generate, in accordance with the signal quality indication, a corresponding signal treatment for each of the one or more sample components of respective sequential samples having a corresponding identified lost part.
