“Popping Sound”

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 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

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.

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.

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).

I have some problem with autoplay.I added event listener on touchend to an element. I want to play audio when i finish drag finger on this element.Everywhere is written that on touchend event audio should be playing, but it doesn't. Audio is playing only if i click fast on the element without drag,I found here: https://bugs.webkit.org/show_bug.cgi?id=149367 that: Allowing media to play on touchstart means that ads videos and audio will autoplay when you scrollCan I suppose that if touchend event comes from drag then audio will not play?

I put a test.mp3 (30 sec) file into the App Bundle. I scheduled an AlarmKit alarm with the file name test.mp3. The custom sound plays ✅ I copied the file from the App Bundle to Library/Sounds/test2.mp3. I scheduled an AlarmKit alarm with the file name test2.mp3. Instead of playing the custom sound, it falls back to the default sound ❌ According to the documentation, sounds placed in Library/Sounds should be playable: I filed report FB19779004 on August 20, but haven’t received any response yet. This functionality is critical for our use case, so could you please let me know whether this is expected to be fixed soon, or if I’m misunderstanding the intended behavior?

When trying to control the sound and haptic feedback on the Apple Watch there is no response whatsoever. The watch does not make a sound or the device does not vibrate when changing the haptic feedback as it should do so. I know this is not a hardware issue due to the fact that the watch does make a charging sound when placed on the charger and when starting a workout. Has anyone else come across the sound settings not working whatsoever or responding to any sort of changes with feedback.

We now have a page at developer.apple.com/audio to assist in finding documentation, videos, and other resources related to the audio frameworks and APIs.

If I want to play musical notes from my iOS app that iOS generates itself, would I need to us Core Audio, MIDI Services, or AVFoundation, or another framework I haven't named?

Im new to Swift and I am trying to create a music application. I was wondering if anyone knows how to save an audio file (.mp3) permanently to the users device so that they can access the music when they are offline.Thanks

Hi, Anyone know if there are a lot of issue requiring Audio Entitlements for CarPlay ? I know a lot of developer have request these entitlements without reply from Apple. Thanks for help me! Andrea

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?

Hi All,I am working on VOIP application, I can clearly heared there is glitch when Starting audio session with Bluetooth connected, and happen on BT connected, HeadSet is fine.[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayAndRecord withOptions:AVAudioSessionCategoryOptionMixWithOthers error:nil];[[AVAudioSession sharedInstance] setActive:YES error:nil];Is there a way to get rid of this glitch?App is registered to monitor Audio Routing changing event, andIt seems to occur when the there's a AVAudioSessionRouteChangeReasonRouteConfigurationChange as notified by AVAudioSessionRouteChangeReasonCategoryChange from no mic input, to mic input.Thanks,
