So how do we use Bluetooth devi

Today's wireless users have no end-to-end requirements for higher capacity, faster access speeds, and higher data throughput capabilities, leading to the increasing radio signal bandwidth of cell base stations. As far as the network is concerned,

You can use the following method:Modify AudioYusuStreamOut. cpp: Copy codeCode: void AudioYusuStreamOut: swS2M (const void * buffer, size_t bytes) { Uint32 Idx_ I; Int16 PCM_M; Short * pbuffer = (short *) buffer; { // Enable software stereo

frequency range when calculating the noise spectrum. In addition to noise suppression, the echo cancellation process eliminates the echo signal generated by the sound coupling between the speaker and the microphone. Echo cancellation works by separating a filtered and delayed copy from the signal received by the microphone. Echo Cancellation technology can calculate the adaptive filter coefficients in wideband speech.HD Voice in a Bluetooth headsetSi

discussing the system architecture, let's take a look at the current situation of audio encoding. Currently, there are many Audio Encoding formats, including PCM, ADPCM, DM, PWM, WMA, Ogg, Amr, ACC, mp3pro, and MP3; for human speech has LPC, CELP and ACELP; other MPEG-2, MPEG-4, H. 264, VC-1 audio and video program encoding format.
