Method for Processing Sound Signal and Terminal Device

A terminal device, comprising:

• a receiver, comprising at least three receiving channels located in different positions of the terminal device, and the at least three receiving channels are used to receive at least three signals emitted by a same sound source, wherein the at least three signals are in a one-to-one correspondence to the channels;
• a processor;
• and
• a computer-readable storage medium storing a program to be executed by the processor, the program including instructions for:
• determining, according to three signals in the at least three signals, a signal delay difference between every two of the three signals, wherein a position of the sound source relative to the terminal device can be determined according to the signal delay difference;
• determining, according to the signal delay differences, the position of the sound source relative to the terminal device;
• and
• when it is determined that the sound source is located in front of the terminal device, performing orientation enhancement processing on a target signal in the at least three signals, and obtaining a first output signal and a second output signal of the terminal device according to a result of the orientation enhancement processing, wherein the orientation enhancement processing is used to increase a degree of discrimination between a front characteristic frequency band and a rear characteristic frequency band of the target signal.
