“Popping Sound”

Where: HTML5What: Audio tag (player) in conjunction with SafariIssue: Performance problemHi guys,There is a noticeable audio delay when using Safari in conjuction with onclick audio events. Specifically: the audio does not sync with the onclick event. The user may click on the icon, link, li etc. and the event takes place but the audio associated with the event does not occur until 1 - 4 secs later. This makes for cumbersom and awkward user experience.Example: https://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_audio_autoplay2notice the slight delay after clicking on enable autoplay*no delay in other browsers such as firefox, chrome, etcI am new to development as well as Safari and Apple. Is this normal? or is there some specific code adjustment needed for Safari. (works fine in all other browsers).*Delay is much more pronouced depending on audio event such as games etc.

Certain apps (eg. DJay) at least seem to have access to audio data from Apple Music streams, either directly or via an indirect dataset for visualization purposes either generated from audio data on the device or delivered from a remote service. Is there any framework provided by Apple or special agreement with Apple that gives access to Apple Music audio data, or sets of visualization meta data, or the ability to run processing of audio data on device or remotely (either on-demand or via preprocessing)?

We're prototyping without the actual hardware, and I'm trying to port a portion of our iOS application to AppleTV. We use Audio Units for recording from the microphone.The Audio Units code seems to work fine. It's querying things like the recording frequency from the simulator, and initializing everything for recording. The hold up is the audio session. The play and record category for AVAudioSession (and all the recording based audio categories) are defined as part of AVFoundation on the AppleTV, but they're not marked as available at runtime.Does the simulator currently not support audio input? Is there a feature to enable it? And I'm assuming the hardware will allow recording for the remote microphone if these APIs are present. Is that the case?

Our app uses multiple AVPlayers at once, some with video, and some with just audio. When trying to airplay it appears that only one of the AVPlayers can play at a time. Is there a setting for the Apple TV to just work as an external audio output rather than it attempting to play a particular AVPlayerItem. We would like all the audios to mix together. Screen Mirroring works ok, but we cant expect all our users to go through the process to enable that and some will select audio airplay.

The audio samples coming from audio connection added to AVCaptureMultiCamSession are very low power compared to AVCaptureSession. This can be easily seen by printing averagePower of audio channels in sample code of AVMultiCamPip & AVCam and comparing. Why is it so?

Hi. Anyone knownn if there is some update or something APPLE done so that i cant get notifications and sound when i try so send information to my app, it has worked until two days ago.

I have updated my ipad 7th gen to ipados18.3 Beta last week and I realized that there is no sound at all no sound from speakers and no sound from bluetooth devices and no sound from airplay, I've checked google and reddit and alot of research people told me its a software bug, i submitted a bug report and now im still waiting for a bug fix update, youtube dosent work neither spotify aswell their UI stops working when i try to use it, So how long do i have to wait for a bug fix? Thanks apple.

Hey all! I'm building a Camera app using AVFoundation, and I am using AVCaptureVideoDataOutput and AVCaptureAudioDataOutput delegates. (I cannot use AVCaptureMovieFileOutput because I am doing some processing inbetween) When recording the audio CMSampleBuffers to the AVAssetWriter, I noticed that compared to the stock iOS camera app, they are mono-audio, not stereo audio. I wonder how recording in stereo audio works, are there any guides or documentation available for that? Is a stereo audio frame still one CMSampleBuffer, or will it be multiple CMSampleBuffers? Do I need to synchronize them? Do I need to set up the AVAssetWriter/AVAssetWriterInput differently? This is my Audio Session code: func configureAudioSession(configuration: CameraConfiguration) throws { ReactLogger.log(level: .info, message: Configuring Audio Session...) // Prevent iOS from automatically configuring the Audio Session for us audioCaptureSession.automaticallyConfig

Hello everyone, I’m new to Swift development and have been working on an audio module that plays a specific sound at regular intervals - similar to a workout timer that signals switching exercises every few minutes. Following AVFoundation documentation, I’m configuring my audio session like this: let session = AVAudioSession.sharedInstance() try session.setCategory( .playback, mode: .default, options: [.interruptSpokenAudioAndMixWithOthers, .duckOthers] ) self.engine.attach(self.player) self.engine.connect(self.player, to: self.engine.outputNode, format: self.audioFormat) try? session.setActive(true) When it’s time to play cues, I schedule playback on a DispatchQueue: // scheduleAudio uses DispatchQueue self.scheduleAudio(at: interval.start) { do { try audio.engine.start() audio.node.play() for sample in interval.samples { audio.node.scheduleBuffer(sample.buffer, at: AVAudioTime(hostTime: sample.hostTime)) } } catch { print(Audio activation failed: (error)) } } This works p

I am work an app development on an app which request an audio function in background as an alert sound. during debug testing , the function work fine, but once I testing standalone without debugging , The function not work , it will play out the sound when I back to app. does any way to trace the issues ?

So currently I using blackhole program to connect the output into input device. I can see that ReplayKit is able to pickup the input and get audio buffer. however, there is no data in the buffer. if there is no data, does that mean there s no audio recorded, or the audio data is store somewhere else?

anyone have the issue when have 2 or more emails and trying to set diffrenet ringtones for each Mail account? No matter what account I pick, it sets the sound for all.

please include the following information in the demo video:utilizing the Background Audio, VoIP and location functionality while your app is running in the background.Please ensure the video you provide shows a physical iOS device (not a simulator).

Hello all,I'm seeing that Final Cut Pro and Garageband use InfoHelper to validate Audio Units now, whereas Logic Pro X still uses auvaltool. After some debugging I've noticed that InfoHelper uses worker threads to instantiate audio units.From what I understand after watching the WWDC video on Audio Unit Extensions, V2 Audio Units should still be loaded 'in-process' by the host, but I see this isn't occuring during validation.Does anyone know if it's possible to use this new flag for instantiating v2 audio units? I have a requirement that the app must be created on the main thread (using Qt as a graphical frontend). Seems that something along these lines may help.CheersDaniel

private let walkAudioSource = SCNAudioSource(fileNamed: Scenes.scnassets/Audio/RamboWalk.wav)! init() { super.init() walkAudioSource.isPositional = true walkAudioSource.load() } private func moveHero() { node.runAction(SCNAction.playAudio(walkAudioSource, waitForCompletion: false), forKey: walkAudioSource) node.runAction(SCNAction.wait(duration: 1.0)) { Swift.print(self.node.removeAction(forKey: walkAudioSource)) self.node.removeAction(forKey: walkAudioSource) } }when executing:moveHero()i can hear the audio playing and see output:self.node.removeAction(forKey: walkAudioSource)but audio is still playingAnybody knows how to stop audio playing?
