How can we avoid echo in the development of the FMS?

1. During use, do not open the microphone settings panel to adjust the volume. It is best to write a volume control program.

2. As the audio publishing end, when an echo is generated, you can reduce the volume of your microphone to effectively reduce the echo.

3. Before publishing the audio to the server, if you need to detect the microphone volume, set setLoopBack to true for the microphone so that you can hear the sound from the speaker, however, when publishing to the server, set setLoopBack to false.

4. If the Echo on one side is too large, you can try the microphone volume on the other side.

5. One SWF can be played at a time on the same client. If more than two SWF files are opened, the two SWF files may play audio from the server at the same time, resulting in the illusion of Echo.

6. All clients must check the microphone in the recording option. If you select sound mixing or wave, the sound mixing or wave will be sent to others as the sound source, if the source contains audio from others, this person may hear his own voice and generate an echo.
