Hi there, whenever I use any third party editing software, the third clip and clips after that have no audio. Here’s how I did it take any third party editing software put 2 clips, cut one in half and delete the other half, cut a half of the 2nd clip Any fixes?

Hello, my app works as Auv3 plugin. I am interested in copying / pasting LogicPro chord track. After I copy chord track in LogicPro and read UIPasteBoard.general in the app, I can see: ["LogicPasteBoardMarker": <OS_dispatch_data: data[0x3024599c0] = { leaf, size = 1, buf = 0x10a758000 }>] How can I access these data? Thank you.

Just installed macOS Sequoia and observed that the mClientID and mProcessID parameters in the AudioServerPlugInClientInfo structure are empty when called AddDeviceClient and RemoveDeviceClient functions of the AudioServerPlugInDriverInterface. This data is essential to identify the connected client, and its absence breaks the basic functionality of the HAL plugins. FB13858951 ticket filed.

I'm developing an app which use "System Audio Recording Only" API to capture system audio. Is there any API to check if app is authorized? So I can instruct user to give my app with this permission. Thanks.

We are using a VoiceProcessingIO audio unit in our VoIP application on Mac. In certain scenarios, the AudioComponentInstanceNew call blocks for up to five seconds (at least two). We are using the following code to initialize the audio unit: OSStatus status; AudioComponentDescription desc; AudioComponent inputComponent; desc.componentType = kAudioUnitType_Output; desc.componentSubType = kAudioUnitSubType_VoiceProcessingIO; desc.componentFlags = 0; desc.componentFlagsMask = 0; desc.componentManufacturer = kAudioUnitManufacturer_Apple; inputComponent = AudioComponentFindNext(NULL, &desc); status = AudioComponentInstanceNew(inputComponent, &unit); We are having the issue with current MacOS versions on a host of different Macs (x86 and x64 alike). It takes two to three seconds until AudioComponentInstanceNew returns. We also see the following errors in the log multiple times: AUVPAggregate.cpp:2560 AggInpStreamsChanged wait failed and those right after (which I don't know if they matter to this issue): KeystrokeSuppressorCore.cpp:44 ERROR: KeystrokeSuppressor initialization was unsuccessful. Invalid or no plist was provided. AU will be bypassed. vpStrategyManager.mm:486 Error code 2003332927 reported at GetPropertyInfo

Tested with library songs on an app targeted to Mac (Designed for iPad). The same app running on iOS queries the same library songs and the duration is expressed correctly in seconds, as expected for the TimeInterval type. Xcode 15.3 MacOS 14.5 FB13821671

Using the hardware volume buttons on the iPhone, you have 16 steps you can adjust your volume to. I want to implement a volume control slider in my app. I am updating the value of the slider using AVAudioSession.sharedInstance().outputVolume. The problem is that this returns values rounded to the nearest 0 or 5. This makes the slider jump around. .formatted() is not causing this problem. You can recreate the problem using code below. @main struct VolumeTestApp: App { init() { try? AVAudioSession.sharedInstance().setActive(true) } var body: some Scene { WindowGroup { ContentView() } } } struct ContentView: View { @State private var volume = Double() @State private var difference = Double() var body: some View { VStack { Text("The volume changed by \(difference.formatted())") Slider(value: $volume, in: 0...1) } .onReceive(AVAudioSession.sharedInstance().publisher(for: \.outputVolume), perform: { value in volume = Double(value) }) .onChange(of: volume) { oldValue, newValue in // Only used to make the problem more obvious if oldValue > newValue { difference = oldValue - newValue } else { difference = newValue - oldValue } } } } Here is a video of the problem in action: https://share.icloud.com/photos/00fmp7Vq1AkRetxcIP5EXeAZA What am I doing wrong or what can I do to avoid this? Thank you

Hi, we have multiple threads in our CoreAudio server plugin carrying out necessary asynchronous work (namely handling USB callbacks and shuffling the required data to the IO). Although these threads have been set up with the appropriate THREAD_TIME_CONSTRAINT_POLICY (which actually improves it) - on M* processors there is an extremely high, non-realtime amount of jitter of >10ms(!) Now either the runloop notification from the USB stack comes that late or the thread driving the runloop hasn't been set up to correctly handling the callbacks in a timely manner. Since AudioUnits threads requiring to comply to the frame deadlines can join the workgroup of the audio device is there a similar opportunity for the CoreAudio server plugin threads? And if so, how should these correctly be set up? Thanks for any hints! Or pointing me to the docs :)

I'm trying to capture audio samples from the selected output device on macOS using ScreenCaptureKit? Thank you

Hi there, I am encountering an issue in my project which utilizes a speech recognizer and occasionally plays audio files. The problem arises when I configure the AVAudioSession and enable voice processing. The system volume changes unexpectedly and becomes uncontrollable. Specifically, the volume is excessively loud on iPhone but quite low on iPad let audioSession = AVAudioSession.sharedInstance() try audioSession.setCategory(.playAndRecord, mode: .default, options: [.defaultToSpeaker, .allowBluetooth, .interruptSpokenAudioAndMixWithOthers]) try audioSession.setActive(true, options: .notifyOthersOnDeactivation) try audioEngine.inputNode.setVoiceProcessingEnabled(true) try audioEngine.outputNode.setVoiceProcessingEnabled(true) I have provided a sample project here: Sample Project. To reproduce the issue, please follow these steps on a real device: Click on "Play recording" to hear the sound at normal volume. Click on "Start recording" to set up the category and speech recognizer. Click on "Stop recording" to stop the recording. Click on "Play recording" again and observe that the sound volume has changed. Thank you for your assistance.

In my app, I only get one interruption notification when a phone call comes in, and nothing after that. The app uses AVAudioEngine. Is this a bug? A very simple repro is to just register for the notification, but not do anything else with audio: struct ContentView: View { var body: some View { VStack { Image(systemName: "globe") .imageScale(.large) .foregroundStyle(.tint) Text("Hello, world!") } .padding() .onReceive(NotificationCenter.default.publisher(for: AVAudioSession.interruptionNotification)) { event in handleAudioInterruption(event: event) } } private func handleAudioInterruption(event: Notification) { print("handleAudioInterruption") guard let info = event.userInfo, let typeValue = info[AVAudioSessionInterruptionTypeKey] as? UInt, let type = AVAudioSession.InterruptionType(rawValue: typeValue) else { print("missing the stuff") return } if type == .began { print("interruption began") } else if type == .ended { print("interruption ended") guard let optionsValue = info[AVAudioSessionInterruptionOptionKey] as? UInt else { return } if AVAudioSession.InterruptionOptions(rawValue: optionsValue).contains(.shouldResume) { print("should resume") } } } } And do this in the app's init: @main struct InterruptionsApp: App { init() { try! AVAudioSession.sharedInstance().setCategory(.playback, options: []) try! AVAudioSession.sharedInstance().setActive(true) } var body: some Scene { WindowGroup { ContentView() } } }

Hello, I can't get my head wrapped around the following problem: I have an external USB microphone capable of samplerates of up to 500 kHz. I want to capture the samples and do analysis and display - no playback required. I can not find a way to run the microphone with its maximum samplerate, I always get 48 kHz. I would like to stick to AVAudioEngine if possible. Any pointer welcome. thx! volker

Hi, I am getting into a trap. Please check stack-trace, howto fix this? regards, Joël stack-trace with ExtAudioFileWrite

When I receive the InterruptionBegan notification (the interruption type is AVAudioSessionInterruptionTypeBegan) , I pause playing music. When I receive the InterruptionEnded notification (the interruption type is AVAudioSessionInterruptionTypeEnded), I resume playing music. however, sometimes i has got the error code: AVAudioSessionErrorCodeCannotInterruptOthers (560557684) If some malicious app to take up the audio, which leads to the third party app music playback recovery fails, an error AVAudioSessionErrorCodeCannotInterruptOthers. In this case, can we know which apps are maliciously hogging the audio?

This code to write UIImage data as heic works in iOS simulator with iOS < 17.5 import AVFoundation import UIKit extension UIImage { public var heic: Data? { heic() } public func heic(compressionQuality: CGFloat = 1) -> Data? { let mutableData = NSMutableData() guard let destination = CGImageDestinationCreateWithData(mutableData, AVFileType.heic as CFString, 1, nil), let cgImage = cgImage else { return nil } let options: NSDictionary = [ kCGImageDestinationLossyCompressionQuality: compressionQuality, kCGImagePropertyOrientation: cgImageOrientation.rawValue, ] CGImageDestinationAddImage(destination, cgImage, options) guard CGImageDestinationFinalize(destination) else { return nil } return mutableData as Data } public var isHeicSupported: Bool { (CGImageDestinationCopyTypeIdentifiers() as! [String]).contains("public.heic") } var cgImageOrientation: CGImagePropertyOrientation { .init(imageOrientation) } } extension CGImagePropertyOrientation { init(_ uiOrientation: UIImage.Orientation) { switch uiOrientation { case .up: self = .up case .upMirrored: self = .upMirrored case .down: self = .down case .downMirrored: self = .downMirrored case .left: self = .left case .leftMirrored: self = .leftMirrored case .right: self = .right case .rightMirrored: self = .rightMirrored @unknown default: fatalError() } } } But with iOS 17.5 simulator it seems to be broken. The call of CGImageDestinationFinalize writes this error into the console: writeImageAtIndex:962: *** CMPhotoCompressionSessionAddImage: err = kCMPhotoError_UnsupportedOperation [-16994] (codec: 'hvc1') On physical devices it still seems to work. Is there any known workaround for the iOS simulator?

I have an app that has the camera continuously running, as it is doing its own AI, have zero need for Apple'video effects, and am seeing a 200% performance hit after updating to Sonoma. The video effects are the "heaviest stack trace" when profiling my app with Instruments CPU profiler (see below). Is forcing your software onto developers not something Microsoft would do?

The above is the extra_data in the lhvC box in the 3D format of Apple's Vision Pro, which only contains sps/pps; I can know that 0xa1 is sps nultype, 0x00 01 is the number of sps, and 0x00 17 is the length. But what is the 0x01 f0 00 fc c3 02 at the beginning, and I can't find the corresponding definition.

I connect two AVAudioNodes by using - (void)connectMIDI:(AVAudioNode *)sourceNode to:(AVAudioNode *)destinationNode format:(AVAudioFormat * __nullable)format eventListBlock:(AUMIDIEventListBlock __nullable)tapBlock and add a AUMIDIEventListBlock tap block to it to capture the MIDI events. Both AUAudioUnits of the AVAudioNodes involved in this connection are set to use MIDI 1.0 UMP events: [[avAudioUnit AUAudioUnit] setHostMIDIProtocol:(kMIDIProtocol_1_0)]; But all the MIDI voice channel events received are automatically converted to UMP MIDI 2.0 format. Is there something else I need to set so that the tap receives MIDI 1.0 UMPs? (Note: My app can handle MIDI 2.0, so it is not really a problem. So this question is mainly to find out if I forgot to set the protocol somewhere...). Thanks!!
