Well yesterday I brought back my car pc to home to make the bluetooth handsfree work. I searched for usb microphones; but I couldn't find one in stores. I didn't want to spend time waiting for a mic. so I didn't buy it from internet... Then I found Logitech Quickcam E2500 webcam! This webcam has an integrated microphone which also work through usb. Also the cam has a softwared echo cancellation system... I plugged the webcam, installed the software and just choose the webcam as microphone. Then entered the webcams program and checked the box "Echo cancellation...." The result is incredible! No echo at all and it is relatively cheap... But the program of the webcam should be running in order to use the echo canceling system...
No announcement yet.
An alternative solution to the echo problem in bluetooth phone...
