“Popping Sound”

Hi everyone !I have developped a virtual audio driver which gets audio samples from the audio engine and sends those samples through the network.It works as expected but I have some issues when using some audio players with hog-mode enabled.While testing my driver with a hog-mode audio player, I was surprised to see that it works, I was just earing the sound from the hog-mode player and other sounds where muted.Sometimes, it doesn't work that well, it seems that the audio engine is broken.To understand what was going on, I add some traces in my audio driver code, at different levels (nub, bus, device, engine), but don't see yet any specific calls from the hog-mode player.Does anyone have an idea how such player can hog the audio device bypassing the driver ? Using AUHAL / HAL perhaps ?Thanks in advance.

Seems like there is a confirmed bug on Xcode12 + iOS14. I have a UINavigationController on each item of a UITabBar, and I've set hidesBottomBarWhenPushed to YES on every secondary ViewControllers, so the TabBar will only be shown on the rootViewController of navigationController. But when I try popping multiple ViewControllers, like pop C from stacks like A-B-C, I found that the TabBar just missing on A. Also another weird part, when I print navigationController.viewControllers in viewWillDisappear: method on C, I found it printing like C-A. How C moved to the top of the array?? This is confirmed on a simple demo app, wonder when it will be fixed.

So, since no more optical audio out, what have you all been using for surround sound system?

I am developing some generalized analytics functions to be performed on real-time audio such as autocorrelation, etc. The analytics results will then be used to control particular audio processing functions (e.g., effects audio units). Does it make sense to define an audio unit type for performing analytics, i.e., an audio unit that doesn't actually process the audio in-band, but only performs some analytics on audio and the results of the analytics are used in real-time to control the processing behavior of another audio unit? If so, can one audio unit be used to control another one? In particular, is there any well defined design pattern or API that allows one audio unit to control another via control signals that are generated as the result of some analytics performed on real-time audio. Any insight into this question or examples of code illustrating such a scenario would be greatly appreciated. Thanks.

The possibility of sending predefined sounds and being able to associate them with images should be implemented in iMessage. For example, the iconic sound of netflix.

How does visionOS play an MP4 audio to Spatial Audio through SwiftUI or RealityKit? Note: Since I can only test the App through Simulator, in order to ensure that my Spatial Audio is played correctly in the space, please tell me how to display the location of Spatial Audio in the space. Ew and how to delete this View after the test, thank you!

I have yet to see proliferation of the apps such as media players that allow for this particular feature - to ignore other audio feeds and continue playing, regardless. So for example,If the media players playing the music station and I use your opens any audio source, Purpose sample YouTube video, the media player would not stop streaming at the radio station. I know for sure that this feature is available because I’ve seen this in one particular app that I will not mention just yet. Anyhow the app allows for an audio stream to continue sleep laying on top of any other audio without stopping. How could this be integrated into an app? thnx ed

Starting from macOS 15 (macOS Sequoia), a new pop-up is triggered: “Local Network Privacy.” We have some questions regarding this new pop-up on MacOS: Running the following simple code: cups_dest_t *dests; int num_dests = cupsGetDests(&dests); triggers the “Local Network Privacy” pop-up. Question: Is this intended behavior? Even if the user presses the “Deny” button, printers can still be iterated, and it is possible to set options for the printer. Is this intended behavior? If so, which actions related to the CUPS library will be denied when the user presses the “Deny” button? Question: Should this pop-up appear for daemons/launchd processes? We found similar questions on some forums, but the answers are unclear. It seems that the pop-up should not appear for launch daemons. We tested the mentioned code with CUPS, and the pop-up was triggered. Is this a bug? If so, will it be resolved before the new macOS version is released? Question: There is somewh

I'm working on a game in which I would like to simulate surround sound (non Dolby encoded audio). I have mono sound effect files that I would like to play on a specific speaker (front left/right, surround left/right, etc) or blend between multiple speakers. Is this possible using any of the various audio frameworks available in tvOS?

On October 4, 2024, the enterprise app we are using showed a (app name) is no longer available pop-up on certain devices and the app was not available. And if those users delete the app and reinstall it, I can't install (app name) because I can't verify integrity, I can't install this app pop up. The profile of the app was renewed in February this year, and membership, certificate, and profile were all not expired. Currently, the problem has been solved by re-deploying the app, Please tell me the cause of the phenomenon and how to take preventive measures.

I am building a iOS app with Ionic and Capacitor. I use AVFoundation inside a Capacitor plugin which provides a public method to play an audio file accessible at a remote URL. The basics work, the audio file is successfully played. Now I want to correctly handle interruptions and background audio. By background audio I mean start playing an audio file while the app is in the background and not continue playing it in the background when it was started in foreground before. To summarize, the app should behave the following way: If another app (e.g. Spotify) is playing audio and my app wants to play audio, the other app should be interrupted and my app's audio should start playing without mixing. If my app's audio is finished playing, the other app's audio should resume. My app must be able to start playing audio without mixing when it is in the background. I want to show a play/pause button and the audio

I have a question in playing audio.When I played a 18kHz pure-tone with iphone6, I heard unnatural sound on lower frequency parts(below 12kHz).But I used iphone6S to played the same 18kHz pure-tone, I heard pure sound on 18kHz. Please refer to the link (*.PNG).I want to know how to solve this problem on iphone6.iPhone 6's photo:https://app.box.com/s/1keuutd653ihqj1jxl35yn0k4krvnt4hiPhone 6s's photo:https://app.box.com/s/sw14l2utuucr7xr4buy1wu3jy33ihblaThanks!

Could anyone play a sound from the Library/Sounds directory using alarmkit? Same file can play in app bundle, but not available in Library/Sounds directory. Is this by design?

My team is responsible for maintaining a web application that uses an iframe to load various web pages that support interaction and audio playback. During use of our application this iFrame may load up to 20 different pages that play audio and interact with our users. Out of 100 users about 3-8 of them the audio will abruptly stop. If the page is reloaded the audio will begin playing for a few seconds then stop again. The only way to reliably to fix the audio playback is to double tap and swipe safari out of view and then reload our application. Things we have checked and tried: Volume is at maximum Volume is not muted Tablet is active and never enters sleep when detected We have confirmed there are not any connectivity issues audio files are completely loaded without error Audio context state registers as playing Audio gain controls are at default Issue surfaced after upgrading to IOS 15.x and was not reported on earlier versions of safa
