Sound Processing Method And Terminal Device

A terminal device, comprising:

• a sound collecting apparatus configured to acquire an analog first sound signal;
• an analog-to-digital conversion apparatus configured to perform analog-to-digital conversion on the first sound signal to generate a digital second sound signal;
• a reverberation apparatus configured to perform reverberation processing on the digital second sound signal to generate a digital third sound signal;
• a digital sound mixing apparatus configured to perform digital sound mixing processing on the digital third sound signal and a background sound signal sent from an application layer to generate a digital fourth sound signal;
• a digital-to-analog conversion apparatus configured to perform digital-to-analog conversion on the digital fourth sound signal to generate an analog fifth sound signal;
• an analog sound mixing apparatus configured to perform analog sound mixing processing on the analog first sound signal and the analog fifth sound signal to generate an analog sixth sound signal;
• and
• a sound playing apparatus configured to play the sixth sound signal,
• wherein the reverberation apparatus and the digital sound mixing apparatus are located at a system bottom layer of the terminal device,
• wherein the system bottom layer comprises at least one of a framework layer, a hardware abstraction layer, a driver layer, and a coder-decoder (CODEC) layer,
• wherein the sound collecting apparatus, the sound playing apparatus, the analog-to-digital conversion apparatus, the digital-to-analog conversion apparatus, and the analog sound mixing apparatus are located at a coder-decoder (CODEC layer), and
• wherein the sound collecting apparatus is connected to the analog sound mixing apparatus through a sidetone channel.
