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 headsetSince the current Bluetooth headset has become
