“Popping Sound”

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.

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

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.

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.

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 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

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.

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 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'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?

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!

I've encountered on my iPod (latest gen, 64 gb) audio dropping out twice recently. Listening to music/podcasts, the audio will just cut out. System indicates the audio should still be playing, but no sound. Using iPod headphones with remote. Remedy was to unplug/reconnect headphones, but very annoying.

Hi all,Sign in pop up appears again and again (sandbox environment). Sometimes after signing is done successfully, the transaction is not happening.Guys this does not happen all the time. And the following lines are available in all the three states (purchased, failed, restored).I checked the country selected in the test user account and it's appropriate. It mostly happens when the previous transaction is interrupted.[[SKPaymentQueue defaultQueue] finishTransaction: transaction]; [[SKPaymentQueue defaultQueue] removeTransactionObserver:self];Guys please help me out on this.yours,Rajai

Hello, I’ve looked at a video and have tons of research and I’m trying to see if there is a way core audio can be created in Xcode as an audio device? “keep in mind” I am totally new to apple’s developer forums and I do not know anything about Xcode nor on how to create an audio device of coreaudio on a Mac since there’s a lot stuff that has do with coding. Nor am I good with that type of technology.

So I have successfully triggered a PTT notification, but when I try to play audio – any audio – it doesn't play. Seems to be an issue with initiating my AVAudioSession. If I do not initiate it, the sound plays (outside of the didActivateAudioSession; such as on view did load), so I know that it's not the audio playing code. For some reason, the AVAudioSession is not allowing me to play sound. Even when I put PlayandRecord and when I put mix in the options
