Embodiments of the present invention provide a sound processing method and a terminal device, where the method includes: acquiring an analog first sound signal; performing analog-to-digital conversion on the first sound signal, so as to generate a digital second sound signal; performing reverberation processing, at a system bottom layer, on the second sound signal, so as to generate a digital third sound signal; performing digital sound mixing processing on the third sound signal and a background sound signal sent from an application layer, so as to generate a digital fourth sound signal; performing digital-to-analog conversion on the fourth sound signal, so as to generate an analog fifth sound signal; performing analog sound mixing processing on the first sound signal and the fifth sound signal, so as to generate an analog sixth sound signal; and playing the sixth sound signal. In the embodiments of the present invention, by performing reverberation beautification processing, at a system bottom layer, on a sound signal, a delay of a sound on which beautification processing is performed can be reduced, thereby implementing real-time input, real-time beautification, and real-time output of the sound and improving user experience. |
