Native Development tool (NDK) allows users to execute some of the program using native code languages such as C/C++. 5. 1. The downside of first approach is that your audio processing also remains in java code, which could potentially be slower than compiled C-Code. 22 // replace the existing AGC, the implementation of which is distributed across: 23 // several classes (namely, GainControlImpl, GainControlForExperimentalAgc,: 24 // AgcManagerDirect and Agc). h> #ifdef AGC_DEBUG //test log. In pre-WebRTC googletalkplugin days, one could disable AGC (automatic gain control for the microphone) by adding audio-flags: 1 to the config file. usually the input of webrtc data is 16kHz) Field trial support to whenever possible turn off the AGC and HPF When operating on mobile devices, where hardware support is available for the AEC and NS functionality, it is desirable to be able to operate without hardcoded behaviors for the WebRTC AGC and HPF.
