[android-developers] Re: Audio Recorder
Hi, Nico.
Thanks for the post. I did that in my checkStorage() method and it
returns the path i am using. Any other thoughts?

Hi,
you should do
String name = Environment.getExternalStorageDirectory().getAbsolutePath() +
/Logger;
to get the right mount point for your sd card.
Hope this helps.

I'm trying to provide an audio recorder within an application for the
user to dictate notes. I keep getting an error that there is no valid
output file and that the external storage is not available (I know it
is because i am using it in a separate activity). Any thoughts would
be appreciated.
private void recordAudio(){
MediaRecorder recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
checkStorage();
recorder.setOutputFile(/sdcard/Logger);
try {
recorder.prepare();
}
catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
recorder.start(); // Recording is now started
}

[android-developers] Re: Audio Recorder
make sure you have the proper permissions to record_audio and
write_external_storage

[android-developers] Re: audio recorder
I seem to be having the same issue I've been playing with different buffer sizes, but this is where I'm at recorder = new AudioRecord (MediaRecorder.AudioSource.MIC, AUDIO_SAMPLE_FREQ, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT, (AUDIO_SAMPLE_FREQ)); it doesnt throw illegalargument, but recorder.getState() returns UNINITIALIZED. If I start recording, I get the same result as you.

[android-developers] Re: audio recorder
I think I found my problem. First - the AudioRecord only seems to work for this combination of parameters: ar_test = new AudioRecord(MediaRecorder.AudioSource.MIC, 8000, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT, 10); (buffer size must be 4096 apparently) and Second - you must have permission for RECORD_AUDIO set in manifest Onward and upward...

[android-developers] Re: Audio recorder format
This is the audio codec for catpured sounds. Default is the same as AMR_NB, this is the audio codec generally used in 3gp videos.
