Hi,Sorry I mean that the signal is not stable. In a sentence that i spoke, there are some words can not listen clearly!Can u show me the best configurations that you've ever done?Thanks!________________________________________2016-05-06 14:49 GMT+07:00 Eugene Punsal Lozada <address@hidden>:Used to have problems on my nexus 6p and it's noise/echo cancellers. When initializing the core I set the following in an attempt to ensure no conflict between the hw and sw echo cancellers.if (core.hasBuiltInEchoCanceler()) {
Log.d(TAG, "Device has built in echo canceler, disabling software echo canceler"); core.enableEchoCancellation(false);
} else {
Log.d(TAG, "Device has no echo canceler, enabling software echo canceler"); core.enableEchoCancellation(true);
}
I also do the following:
- request audio focus when in a call so that its not interrupted by other audio events (like notifications from other apps etc...). release it after the call ends.
- I set the audio manager mode to MODE_IN_COMMUNICATION and revert it back to normal after the call.
I'm not sure which of the above exactly helped resolve my nexus6p problems, but my calls have been clear ever since.

echolimiter=1Is it depend on what kind of codec that I use?Thanks!________________________________________2016-05-06 13:57 GMT+07:00 Nabeel <address@hidden>:Hi,
For issue 1, I disabled Noise Suppression module and Automatic Gain Control module. For issue 2, I enabled Echo Limiter module (see http://www.linphone.org/technical-corner/linphone/documentation). That seems to have fixed these issues.

Hi Nabeel,I also get this issue like u and haven't found solution to fix.Do u fix this issue? If yes, please show me the solution.Thanks!________________________________________2016-04-01 3:05 GMT+07:00 Nabeel <address@hidden>:Hello,
I am using Linphone on Android and have the following modules enabled:
1. Noise Suppression
2. Acoustic Echo Cancellation
3. Automatic Gain ControlAlthough the sound quality is very good, there are a couple of issues:
1. The very first part of each sound / sentence gets chopped out (fraction of a second), possibly due to the microphone use not being sensitive enough.
2. On some phones, the caller can hear an echo of their own voice, regardless of whether they have the loudspeaker on or off or whether the volume is high or low.
Please advise which settings can be used to fix these issues.
Nabeel
