Acoustic signal processing method and apparatus

Main voice processing is performed on an acoustic signal at a basic sampling frequency fs within one period of the basic sampling frequency fs to allow the main voice processing implemented acoustic signal to undergo down-sampling for implementing voice processing for acoustic effect to the acoustic...

Beschreibung
Zusammenfassung:	Main voice processing is performed on an acoustic signal at a basic sampling frequency fs within one period of the basic sampling frequency fs to allow the main voice processing implemented acoustic signal to undergo down-sampling for implementing voice processing for acoustic effect to the acoustic signal at another sampling frequency +E,fra 1/2+EE fs or one half the basic sampling frequency to allow the acoustic signal which has been subjected to voice processing for acoustic effect to undergo up-sampling and thus to continuously carry out the main voice processing by the basic sampling frequency fs and the voice processing for acoustic effect by another sampling frequency +E,fra 1/2+EE fs.
