Warped linear predictive coding (warped LPC or WLPC) is a variant of linear predictive coding in which the spectral representation of the system is modified, for example by replacing the unit delays used in an LPC implementation with first-order all-pass filters. This can have advantages in reducing the bitrate required for a given level of perceived audio quality/intelligibility, especially in wideband audio coding.

Property Value
dbo:abstract
  • Warped Linear Predictive Coding (WLPC、ワープLPC) 、あるいはWarped Linear Prediction(WLP、ワープLP)は線形予測符号の一種で、通常の線形予測での周波数特性をバーク尺度やメル尺度のような人間の聴感特性に合わせて変形させることに特徴がある。WLPC は、周波数スペクトルを人間の聴覚に合わせた分解能でモデル化することができ、より少ないパラメータで音の情報を表現することができるため、音声認識や広帯域音声符号化などに向いている。 (ja)
