Hi @igorski
By any chance is there way to amplify the input voice other than setVolume to input channel?

Thanks in advance

Hi @YogarajRamesh

Sadly Android OS does not allow directly setting the microphone volume. What you can do is add some UI to your application where the user can adjust their microphone volume if they notice it is too low.

By adding the Gain processor to the input channels processing chain, you can introduce amplification of the input signal without introducing any sound shaping side effects that change the sound timbre. You can link your UI control to the setAmount( float value)-method of the Gain processor.

Gain gainProcessor = new Gain();
AudioChannel inputChannel = _engineRef.getInputChannel();
inputChannel.getProcessingChain().addProcessor( gainProcessor );
gainProcessor.setAmount( ...floating point value in 0 to 20 range );

Hi @igorski,
Thanks for your response

error: cannot find symbol
Gain gainProcessor ;

symbol: class Gain
location: class MWEngineActivity

Thanks in advance

It was added in 05b76c0 so you need a fairly recent build of the library.
