objective c - How to record audio through an iPhone app?

Question

I want to record audio in my iPhone app and once the audio is recorded I want a dialog box to open which asks for the filename.

And then I want to save the audio with that filename into my app. How can I do so?

Answer 1

try using AVAudioPlayer and AVAudioRecorder classes for audio recording and playback.Initially you have to establish an audio session using AVAudio session class

AVAudioSession *audioS =[AVAudioSession sharedInstance];
[audioS setCategory:AVAudioSessionCategoryPlayAndRecord error:&error];
[audioS setActive:YES error:&error];

NSURL *url = [NSURL fileURLWithPath:@"/dev/null"];

NSDictionary *settings = [NSDictionary dictionaryWithObjectsAndKeys:[NSNumber numberWithFloat: 44100.0],AVSampleRateKey,
[NSNumber numberWithInt: kAudioFormatAppleLossless], AVFormatIDKey,
[NSNumber numberWithInt: 2],AVNumberOfChannelsKey,[NSNumber numberWithInt: AVAudioQualityMax],         AVEncoderAudioQualityKey,
                          nil];

and then initialize the recorder and player classes...Hope this helps
