It is said that Wuxi Zhongxing Microelectronics Co., Ltd. has launched such a patent.
Principle: Using the method of processing audio data in Bluetooth headset, the audio data processing function in Bluetooth headset is realized, and the purpose of voice conversion is achieved.
The method comprises the following steps: processing a digital audio signal to obtain a fundamental frequency and a * * * peak frequency, and adjusting the period of the fundamental frequency according to a preset fundamental frequency adjustment rate to obtain a digital audio signal after the fundamental frequency adjustment;
Filtering the adjusted digital audio signal to shift the peak frequency of * * * to the set frequency value, and obtaining the voice-converted digital audio signal and sending it. The invention also discloses a device for processing audio data in the Bluetooth headset and the Bluetooth headset.
