Recording audio in Swift

Question

Does anyone know where I can find info on how to record audio in a Swift application? I\'ve been looking at some of the audio playback examples but I can\'t seem to be able

Answer 1

Swift2 version of @codester's answer.

func record() {
    //init
    let audioSession:AVAudioSession = AVAudioSession.sharedInstance()

    //ask for permission
    if (audioSession.respondsToSelector("requestRecordPermission:")) {
        AVAudioSession.sharedInstance().requestRecordPermission({(granted: Bool)-> Void in
            if granted {
                print("granted")

                //set category and activate recorder session
                try! audioSession.setCategory(AVAudioSessionCategoryPlayAndRecord)
                try! audioSession.setActive(true)


                //get documnets directory
                let documentsDirectory = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0]
                let fullPath = documentsDirectory.stringByAppendingPathComponent("voiceRecording.caf")
                let url = NSURL.fileURLWithPath(fullPath)

                //create AnyObject of settings
                let settings: [String : AnyObject] = [
                    AVFormatIDKey:Int(kAudioFormatAppleIMA4), //Int required in Swift2
                    AVSampleRateKey:44100.0,
                    AVNumberOfChannelsKey:2,
                    AVEncoderBitRateKey:12800,
                    AVLinearPCMBitDepthKey:16,
                    AVEncoderAudioQualityKey:AVAudioQuality.Max.rawValue
                ]

                //record
                try! self.audioRecorder = AVAudioRecorder(URL: url, settings: settings)

            } else{
                print("not granted")
            }
        })
    }

}
