[android-developers] Re: Recording Audio
Hi, the following code works for me.
I was also getting the Start failed. error at one point. Fixed it by
changing my output file extension from .3gpp to .audio
-Ben
final String path = /sdcard/recording + System.currentTimeMillis() +
_ + (int)(Math.random() * 1000)+ .audio;
final MediaRecorder mr = new MediaRecorder();
mr.setAudioSource(MediaRecorder.AudioSource.MIC);
mr.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);
mr.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
mr.setOutputFile(path);
mr.prepare();
mr.start();
//stop recording after 10 seconds
Timer t = new Timer();
t.schedule(new TimerTask() {
public void run() {
//stop recording
mr.stop();
mr.release();
}
}, 10*1000);

Hi Ben,
Since the tutorial's currently broken, do you mind posting what values
you put in instead of these broken lines:
recorder.getMimeContentType()

If you got everything working, would you be willing to post your code
(since the tutorial's not yet updated)?

Alternatively, each application has its own private data directory /
data/app-private/app-package. I believe your working directory is set
to this directory by default. This is onboard flash, so it will
survive the user ejecting an SD card. However, there is a limited
amount to go around, so you don't want to store monster media files
there.

Yep, figured that much by the method name, but what's a valid path? I
mean I'm figuring it's UNIX-like, but other than that I'm in the
dark. Is there a preferred place for apps to store data? Are there
certain directories that I have permission to write to? What
directories exist on the device by default? It'd be nice for the docs
on data storage to mention any of these
things:http://developer.android.com/guide/topics/data/data-storage.html
You can take a look at the source to SoundRecorder in the open

Thanks for the example. This would be a much better example than the
one in the docs that won't compile and implies content must first be
added to a database:

I'm having a very hard time getting started. Mostly I'm just hoping
that someone from Google reads this and will update the
documentation
because the example won't compile - it looks like it's from some
previous version of the SDK because there's an error in every other

One question I had is whether I can just specify an arbitrary path

I'm still feeling directionless when it comes to what MediaRecorder.setOutputFile(String path) is expecting. Is it a relative path? Is it a fully qualified path? Must the directory we are recording in already exist, or will MediaRecorder create it for us if it does not exist? What happens if we specify a file path which already exists - will it override the existing file or will it bomb out?

Hi,
I've written a little program (see below) to record audio using
MediaRecorder. While everything works fine in the emulator (SDK1r2),
the program does not work on the real phone (HTC G1). On the phone,
after pressing the start button, the audio file is created, but no
content is written to it (i.e. the file size remains 0). Also, no
exception is shown in logcat, and no AudioStreamInGeneric events are
generated (such events are generated when running the program on the
emulator).
Is there maybe a setting on the phone that I have to turn on (or off)?
Or am I missing something else?
I've set the permission to record audio in the android-manifest.xml
file using
uses-permission android:name=android.permission.RECORD_AUDIO/uses-
permission
Thanks for any help!

[android-developers] Re: Recording audio stream
I can't give you specifics about deployment because: (a) I don't know, it's up to the carrier and manufacturer to decide when they deploy new releases (b) Even I did know, there's a fairly good chance I couldn't tell you due to NDA's we have with our partners You can see the code in development on the Cupcake branch at android.git.kernel.org.

[android-developers] Re: Recording Audio
To Record audio to a new file on sd card I did as follows and worked for me
with emulator and mic. But don't know about buffers or sockets. And not sure
if this is a good way but anyway works.
To run emulator with sd card you do mksdcard 512M sdimg.iso then start
emulator as 'emulator.exe -sdcard sdimg.iso'
private void startRecord() {
mRecorder = new MediaRecorder();
mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mRecorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);
mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
mRecorder.setOutputFile(/sdcard/test.3gpp);
mRecorder.prepare();
mRecorder.start();
}
then elsewhere mRecorder.stop();
then to play
mPlayer = MediaPlayer.create(context, Uri.parse(mFilePath));
mPlayer.start();
Also I have
uses-permission android:name=android.permission.RECORD_AUDIO
/uses-permission

Hi,
I want to record audio from the emulator using the mic. Can anyone
send me some sample code on how to do this.
Also, I want to know whether it is possible to redirect this mic o/p
to a memory buffer or network socket.
Cheers,
Earlence

I am developing an app for recording audio annotations during an event (the annotations get recorded as audio files on the sdcard): https://sourceforge.net/projects/rehearsalassist/ The source is available in the SVN repository. The following two files (RehearsalRecord.java and RehearsalPlayback.java) deal with recording/playback: http://tinyurl.com/ax8ju5 http://tinyurl.com/7rsfcf I don't know about the redirection part.

Thanks. how can I seutp the emulator to record audio?

[android-developers] Re: Recording Audio
I'm using Windows and the only thing I did to the emulator was to emulate sd
card as below. For some reason sd card seems to be necessary for sound
recording.
Apart from that, provided that your mic works with Windows, there's no need to
setup anything. I don't know about Ubuntu but it should be the same.

It's probably not really streaming audio. Some people are working around the issue by tailing the file as it is being written.
