Dear AppleI am currently using your iPad Pro 12,9” for a lot of my work editing using Lightroom Mobila, Photoshop mobile and the LumaFusion video app.As a photographer it was great to get the support of RAW files, especially when importing the DSLR picture files from SDcard into the ipad.But when doing video editing on the iPad, I am missing the ability to import external recorded sound from an SDcard into the iPad. The Apple Lightning adapter is only supporting video and picture files, but not sound files. Whe is that?The only way I can get my external recorded sound into the LumaFusion video app, is to use a wifi hotspot unit that support SDcard. By using that unit i am able to connect my ipad to the hotspot and transfer the audio files into the ipad, where I then can use it for my video editing.Juse downloaded the beta version of iOS 11 on my iPad Pro and was hoping that the function of letting me import sound files into the ipad by using the original Apple ligh

Hello fellow developers, I am currently working on my bachelor thesis. Therefore my task is to develop a rudimentary solution to stream 2 channel audio from MacOS to an IOS device over Wifi, highest quality possible. Latency is not a major concern, but keeping it low would be great. So i thought of developing something like Wifi2Hifi. That would probably be as rudimentary as possible. I'm not very deep inside the subject. Still researching and collecting thoughts and ideas. If someone could point me to sources and literature on audio related networking/streaming, i would be glad. Also thoughts on networking protocols i could use, or api's etc., would be greatly appreciated. Thanks a lot.

when using my 2015 Version MacBook pro plugged into my audio interface for playback I'm getting a crackling noise. When I playback directly from my mac with headphones or through the CPU speakers it plays fine. I've tried replacing the interface, cords & wires and still no luck. if I cant fix this I'll probably sell my mac.

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

How to identify recording audio is pleasant or unpleasant in iOS. I am recording of a motor vehicle sound and want to measure sound is pleasant/unpleasant or noisy means basically want to measure motor sound of vehicle for maintenance in iOS.

Hi All I need to be able to capture the audio being sent to a specific audio driver (such as internal speakers) and manipulate it - is there a specific API that allows me to capture audio without inserting anything into the audio graph? (Use case is to add audio to an NDI video feed for ingestion into another application) Thanks!

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

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?

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.

I am working on an iOS app for mixing an audio file with the user's voice input into a new file, and playing the content of this audio file simultaneously. You can just consider this app as a Karaoke player which records both the singer’s voice and the original soundtrack into file while playing the original soundtrack for the singer.I use AUGraph to establish the audio process flow as:One mixer AudioUnit (with type kAudioUnitType_Mixer and subtype kAudioUnitSubType_MultiChannelMixer) with 2 inputs;One resampler AudioUnit for necessary sample rate converting( kAudioUnitType_FormatConverter, kAudioUnitSubType_AUConverter) from the sample rate of the audio file to that of the mic input in order to make formats of the mixer's 2 input buses match;Then connect these nodes: Mic’s output(output element of IO node's input scope) —> Mixer’s input 0, Resampler’s input —> Mixer’s input 1, Mixer’s output —> Speaker’s input(input element of IO node's output scope);Set a render

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
