"android.media.audiofx" supported?

[torus1000]

Hi i.MX Experts,

It seems linuxBSP(gstreamer) supports audiofx.
Does i.MX6Sabre AndroidBSP also support audiofx such as AEC(AcousticEchoCanceler)?

P.S.

I tested startStreaming() in following URL but NULL returned when .create() called. Please see *3

Thanks.

package com.example.audiotest;

public void startStreaming() {

  recorder = new AudioRecord(MediaRecorder.AudioSource.VOICE_RECOGNITION,sampleRate,channelConfig,audioFormat,minBufSize);
  AcousticEchoCanceler canceler =  AcousticEchoCanceler.create(recorder.getAudioSessionId());

}

Hi torus1000

I am afraid it is not supported by low level, for VoIP

it may be recommended to look at LS1024 products
