AcousticEchoCanceler on Samsung devices not working

由 霸气de小男生 提交于 2020-05-12 11:50:07
问题 I have AcousticEchoCanceler working for VoIP calls for every other device type I've tried, but not on any Samsung device.

问题 On different systems (Windows/Android/etc.) there are some "built-in" audio enhancements. For example AEC (autmatic echo cancellation), NR (noise reduction) and Automatic Gain Control. Everyone can have those turned off or on in any combination. There are also audio enhancements on some browsers (i know about Chrome and Firefox) It is possible to turn them all off using webRTC?
