1. An audio compression system for a bluetooth wireless communication, comprising:
an audio compression device for wireless communication, comprising:
a first signal transceiver;
a first processor connected to the first signal transceiver, obtaining an audio signal and an available bandwidth; and
an encoding module connected to the first signal transceiver;
wherein the first processor performs an audio compression encoding to the audio signal to obtain a sample audio signal, performs a comparison procedure with the audio signal and the sample audio signal to generate a residual signal, performs a signal modulation to the residual signal to generate a plurality of residual encoding frames and transmits the residual signal according to the available bandwidth;
wherein the encoding module performs the audio compression encoding to the residual signal to obtain a plurality of residual headers and a residual encoding signal; and
an audio decompression device connected to the audio compression device for wireless communication, comprising:
a second signal transceiver in communication with the first signal transceiver and receiving the residual encoding frames; and
a second processor connected to the second signal transceiver, which moves the residual encoding frames from the available bandwidth to an original time point according to a plurality of headers of the residual encoding frames;
wherein, when receiving the residual encoding frames, the audio decompression device could perform an audio compression decoding to the residual encoding frames to generate the residual signal, and could perform a signal superposition computation according to the residual signal to generate the audio signal.
