“Popping Sound”

Hello, I started to set audio stereo recording (both audio and video are recorded) and the audio quality seems to be lower than quality obtained with native camera application (configured for stereo). Using console to check the log, I found a difference between camera app and mine regarding MXSessionMode (of mediaserverd) in fact, camera application gives MXSessionMode = SpatialRecording and mine MXSessionMode = VideoRecording How can I configure capture session to finally have MXSessionMode = SpatialRecording? Any suggestion? Best regards

Is anyone having issues with inputs on external interfaces such as motu, apollo or presonus usb/firewire/thunderbolt 2/3 devices? Specifically the motu ultralite mk3 hybrid. the drivers work in high sierra but in mojave for some reason the inputs are showing in audio midi setup but are completely greyed out. Outputs are working fine

I'm using Release 34 (Safari 11.0, WebKit 12604.1.27.0.1)I use the following code to get microphone input and forward the audio to speakers -- note that I use headset so no feedback.var _streamSource; var _audioContext= new webkitAudioContext(); function startMic() { var constraints = { audio:true, video:false }; navigator.mediaDevices.getUserMedia(constraints). then(micStarted).catch(micDenied); } function micStarted(stream) { _streamSource= _audioContext.createMediaStreamSource(stream); _streamSource.connect(_audioContext.destination); } function micDenied(error) { console.log(error) }The audio playback of mic input is horribly distorted with a buzzing sound which makes it hard to listen to. I tried the same code in other browsers and the microphone audio plays back fine without buzz.

Hi Apple Team, We have a technical query regarding one feature- Audio Recognition and Live captioning. We are developing an app for deaf community to avoid communication barriers. We want to know if there is any possibility to recognize the sound from other applications in an iPhone and show live captions in our application (based on iOS).

I want to use the APPs to listen to spatialized audio that I am synthetically generating, and have that audio be in a certain location with respect to the head. As you turn your head, the sound moves. As you walk around you can hear the sound moving in different positions. Is there example code of this out there? How do I make this happen on iOS? There are so many APIs out there for outputting sound on iOS, which one would be the quickest to get the spatialized 3D audio working?

Hello,I want to do recording and playing back audio on my iOS device.Can someone give me a short hint, which classes are useful for this use case?I googled around this topic a lot and read a lot of different things.But I'm not really sure, what classes are the right one for me.Examples: AVAudioSinkNode, AVAudioSourceNode, AVAudioSession, AVAudioRecorder,AVAudioPlayer, AVAudioQueue etc. Maybe someone could show me a code snippet or sample project (if possible).My current state: I would try it with AVAudioRecorder and AVAudioPlayer.My Recorder class logic:if let dir = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first { let file = dir.appendingPathComponent(audiofile.wav) // setup audio session with crazy framework let format: [String: Any] = [AVSampleRateKey: 44100.0, AVNumberOfChannelsKey : 2, AVFormatIDKey: kAudioFormatLinearPCM, AVEncoderBitRateKey: 320000, AVEncoderAudioQualityKey : AVAudioQuality.high.rawValue] recorder = try AVAudioRecorder.init(url: file, sett

Hello,I'm developing a pre-amp that will accept a music stream over ethernet. On OSX side, I'm writing a driver (just plugin) that will take system audio and send it over ethernet. I'm able to collect the audio data. Now I need to figure out how to stream it out.What is the proper way to do sockets in an audio plugin? I tried using socket callbacks with CFRunLoop but it seems to be freezing all of coreaudiod. Any other suggestion on this architecutre will be appreciated. For example, does anyone see a need for a kernel level driver or will the plugin suffice?Thanks,Konstantin

We've been using remote push notifications from a gateway to allow us to provide auth information. In some cases there's no sound to tell the user that a notification has arrived. In our code we specify UNAuthorizationOptionSounds, and the notification settings on the devices are set to allow notifications and sounds for the application. The client code hasn't changed in a couple of years, so I'm wondering whether something might have happened from the sending side. That's not my strongest area though. Does anyone know whether there could have been a change in the call generating the push notification which cut off the sound, and where I would look for documentation on that?

I have a link in a UITextView in a ViewController which is part of a UINavigationControler, which I present as Modal. When I do a Peek and pop (force touch /3d touch) twice on the link it opens the link in Safari which is default behavior. But When I go back to my app, the View controller is dismissed. Does anyone have encountered this issue and know how to stop the view controller being dismissed.Thanks in Advance.

Hello,We are trying to send compressed audio data over BLE.Our test setup includes a Linux PC(Peripheral) and an iPhone acting as the Central.We have the below characteristics on the Peripheral for audio transfer.Char1 (Read | Notify)Char2 (Write)We have an use case where audio transfer happens both ways simultaneously using these two characteristics.Peripheral -> Central (using Char1)Central -> Peripheral (using Char2)The Peripheral -> Central transfer seems to be fast enough for audio playback.But with the Central -> Peripheral transfer, we see a considerable lag.This transfer takes more than double the time required for Peripheral -> Central transfer.We also tried sending a connection parameter update request to set the connection interval between 20-21ms.But still we see no increase in the transfer speed.Are we missing out something here that enables faster transfer rates when sending data from the iPhone to PC?
