Can i record audio using Phonegap

[Hareem Ul Haque]

Is it possible to use Phonegap to record audio using the device's
microphone.

And is it possible to sync the local contacts list with Phonegap app.


Are the above possible for the Android platform

Hareem,

Here's an example of audio recording:

//-------------------------------------------------------------------------
// Audio recorder
//-------------------------------------------------------------------------
var mediaRec = null;
var recTime = 0;

/**
* Record audio
*/
function recordAudio() {
console.log("recordAudio()");
console.log(" -- media="+mediaRec);
if (mediaRec == null) {

var src = "myrecording.mp3";
mediaRec = new Media(src,
function() {
console.log("recordAudio():Audio Success");
},
function(err) {
console.log("recordAudio():Audio Error: "+err);
setAudioStatus("Error: " + err);
},
function(status) {
console.log("recordAudio():Audio Status: "+status);
setAudioStatus(Media.MEDIA_MSG[status]);
}
);
}

navigator.notification.beep(1);

// Record audio
mediaRec.startRecord();

// Stop recording after 10 sec
recTime = 0;
var recInterval = setInterval(function() {
recTime = recTime + 1;
setAudioPosition(recTime+" sec");
if (recTime >= 10) {
clearInterval(recInterval);
mediaRec.stopRecord();
console.log("recordAudio(): stop");
navigator.notification.beep(1);
}
}, 1000);
}

You can retrieve the local contacts using:

function getContacts() {
obj = new ContactFindOptions();
obj.filter = "";
obj.multiple = true;
obj.limit = 1000;
navigator.service.contacts.find(
["displayName", "name", "phoneNumbers", "emails", "urls", "note"],
function(contacts) {
var s = "";
if (contacts.length == 0) {
s = "No contacts found";
}
else {
s = "Number of contacts: "+contacts.length+"<br><table
width='100%'><tr><th>Name</th><td>Phone</td><td>Email</td></tr>";
for (var i=0; i<contacts.length; i++) {
var contact = contacts[i];
s = s + "<tr><td>" + contact.name.formatted + "</td><td>";
if (contact.phoneNumbers.length > 0) {
s = s + contact.phoneNumbers[0].value;
}
s = s + "</td><td>"
if (contact.emails.length > 0) {
s = s + contact.emails[0].value;
}
s = s + "</td></tr>";
}
s = s + "</table>";
}
document.getElementById('contacts_results').innerHTML = s;
},
function(e) {
document.getElementById('contacts_results').innerHTML = "Error:
"+e;
},
obj);
};

Currently, saving contacts is not supported.

Documentation is available for these features at http://docs.phonegap.com.

Thanks for the info. The code example you showed me. Is it possible to
do so on Android or its only for Iphone.

I do have an audio record/playback example working on my Android phone
(Droid Incredible, OS 2.2).

Now, I know Android's audio file format is not mp3 (though I did
export it to my PC to see if it'd play since the example in the
Phonegap docs called it an .mp3 extension). I recall reading
somewhere what the audio file format is, but can't seem to find it
now.

What file type is the audio that is captured by this recording
method? And what's the file type recorded from iOS?

I'm looking to save these files to a server for review, so they'd be
coming from different devices and I'm just trying to figure out what
sort of review toolset we'd need.

This is the code that setups up the Audio recording on Android from
com.phonegap.AudioPlayer.java.

this.recorder = new MediaRecorder();
this.recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
this.recorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);
// THREE_GPP);
this.recorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT); //AMR_NB);

And if you look up the support audio codecs on the Android Developer site:

http://developer.android.com/guide/appendix/media-formats.html

I don't know what we are using for iPhone.

So am I correct in thinking I could alter the source code for those
lines to specify mp3 format as the output format / audio encoder?

[ericburnley]

duh, i didn't read that chart correctly.

I see the encoder does not support MP3 as a file type. Thanks.

Guess I'll look into 3GP -> MP3/WAV file conversion next... if
anyone's done that research already, links/ideas on that would be
appreciated.

[Simon MacDonald]

yes
