audio-recording

问题 Adding microphone audio input to AVCaptureSession seems to disable UIImpactFeedbackGenerator . let audioDevice = AVCaptureDevice.defaultDevice(withMediaType: AVMediaTypeAudio) let audioDeviceInput = try AVCaptureDeviceInput(device: audioDevice) if self.session.canAddInput(audioDeviceInput) { self.session.addInput(audioDeviceInput) } Once the audio device is removed, feedback resumes. Is this normal behavior? Is there a way around this? I notice stock iOS Camera app in video mode and long

问题 I'm recording a video with the camera, using the MediaRecorder class, after following a tutorial similiar to this http://androidcookbook.com/Recipe.seam;jsessionid=40151FCD26222877E151C3EEFB406EED?recipeId=1375&recipeFrom=ViewTOC And I want while recording, to be able to mute / unmute the microphone. How's that possible? I'm setting the audio source at start mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER); mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA); But

问题 With browser Web API, I'd like to set MediaDevices.getUserMedia constraints attributes, suitable to record audio speech (voice messages), e.g. setting these parameters: mono 16bit 16KHz Here my code: const mediaStreamConstraints = { audio: { channelCount: 1, sampleRate: 16000, sampleSize: 16, volume: 1 }, video: false } navigator.mediaDevices.getUserMedia(mediaStreamConstraints) .catch( err => serverlog(`ERROR mediaDevices.getUserMedia: ${err}`) ) .then( stream => { // audio recorded as Blob

问题 whenever the code reaches inputNode.installTap(onBus: 0, bufferSize: 1024, format: recordingFormat) {[weak self] (buffer:AVAudioPCMBuffer, when:AVAudioTime) , app is crashing with following error Terminating app due to uncaught exception 'com.apple.coreaudio.avfaudio', reason: 'required condition is false: format.sampleRate == hwFormat.sampleRate' I tired removing taps before adding another and I'm making sure I'm not adding more than one tap. what is weird is that the app is working fine
