bitrate for amr can not be changed on android MediaRecorder
<p>i need to record speech with 5.15kbit/s encoding rate. but as i see at android MediaRecorder object i can not change this property with setAudioEncodingBitRate method. here is my code.but it sills encode speech with 12.2kit/s encoding rate ? how can change it ?</p>

<p>also any other application that can change encoding rate of an existing speech might be useful for me.... </p>

<pre><code>myMediaRecorder=new MediaRecorder();
myMediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
myMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
myMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);     
myMediaRecorder.setAudioSamplingRate(8000);
myMediaRecorder.setAudioEncodingBitRate((int)(5.15 * 1024));
</code></pre>
