摘要: An audio encoder has a window function controller, windower, time warper with final quality check functionality, time/frequency converter, TNS stage or quantizer encoder, the warper, an additional noise filling analyzer are controlled by signal analysis results obtained warp classifier. Furthermore, decoder applies operation using manipulated estimate depending on harmonic speech characteristic of signal.
