I use SoundAnalysis to analyze background sounds and have enabled background permissions. It worked well in previous iOS systems, but a warning appeared in the new iOS18beta version and sound analysis was stopped. Warning List: Execution of the command buffer was aborted due to an error during execution. Insufficient Permission (to submit GPU work from background) [Espresso::handle_ex_plan] exception=Espresso exception: "Generic error": Insufficient Permission (to submit GPU work from background) (00000006:kIOGPUCommandBufferCallbackErrorBackgroundExecutionNotPermitted); code=7 status=-1 Unable to compute the prediction using a neural network model.

Hello there, We currently have a crash in prod when executing the following line: let classificationRequest = try SNClassifySoundRequest(classifierIdentifier: .version1) It appears to only happen on iOS 17+ and only when regaining audio focus after an interruption in a background state. We are aware this call probably fails because it is happening from a background state - however - I would expect then that the SNClassifySoundRequest throws some kind of error since it is already an initializer that throws. If it is possible for the call to fail under certain circumstances, then could SNMLModelFactory throw an error instead of using try! ? Full trace below: SoundAnalysis/SNMLModelFactory.swift:112: Fatal error: 'try!' expression unexpectedly raised an error: Error Domain=com.apple.CoreML Code=0 "Failed to build the model execution plan using a model architecture file '/System/Library/Frameworks/SoundAnalysis.framework/SNSoundClassifierVersion1Model.mlmodelc/model1/model.espresso.net' with error code: -1."

Hello, I can see many apps that analyzes sound from microphone in real time. Is there another library like Audiokit or all of them are made with Audiokit?? Thanks

I'm working with MLSoundClassifier to try to look for 2 different sounds in a live audio stream. I have been debating with the team if it is better to train 2 separate models, one for each different sound, or train 1 model on both sounds? Has anyone had any experience with this. Some of us believe that we have received better results with the separate models and some with 1 single model trained on both sounds. Thank you!

I've only been using this late 2021 MBP 16 for nearly 2 years, and now the speaker is producing a crackling sound. Upon inquiring about repairs, customer service informed me that it would cost $728 to replace the speaker, which is a third of the price of the laptop itself. It's absolutely absurd that a $2200 laptop's speaker would fail within such a short period without any external damage. The repair cost being a third of the laptop's price is outrageous. I intend to initiate a petition in the US, hoping to connect with others experiencing the same problem. This is indicative of a subpar product, and customers shouldn't bear the burden of Apple's shortcomings. I plan to share my grievances on various social media platforms and if the issue persists, I will escalate it to the media for further exposure.

I am working on a design that requires connecting an ios device to two audio output devices specifically headphones and a speaker. I want the audio driver to switch output device without user action. Is this manageable via ios SDK?

Hi, I have been trying to connect my microphone on my reason studio for days now without any outcome. So I was asked to download ASIO Driver on my mac. I realised that I have an IAC driver. I need help on downloading the Asio driver and wish to know if there will be a problem running it with the IAC driver. I also just upgraded without knowing from ventura to sonoma. Am using an audio iinterface(Focusrite scarlett solo to connect to the reason application and my mic is nt1-a rode but I can get a sound but cannot record. Will be overwhelmed if I can get help from here. Thanks

Is it possible to pick the user's current device tone/sound as the Push Notification sound for my app programmatically. So that s/he does not miss out any notification just because of unsustainable sound. I have gone through the UNNotificationSound Class, it provides the option to opt either the default or the custom sound. But, my concern is to auto pick the sound which user is using on his/her mobile. Thanks in advance!

Please Teach me. I wan't to get list of SystemSoundId. (relation can file) (Officially if possible) (example) 1001 - mail-sent.caf 1002 - Voicemail.caf 　・ 　・ I know where [.caf] file in iPhone. /System/Library/Audio/UISounds/ but, I don't know relation [.caf] and soundId.

Hi Developers, Requesting you to please fix the default notification tone "Rebound", its too low and short. I'm missing most of my notifications.

It is so frustrating and the second time this has happened to me. I found a fix for the first time, but can't seem to find one now. Help! Anyone know what to do to stop the noise? Lisa

I was play a pcm(24kHz 16bit) file with AudioQueue, and it mix with other sound( 192kHz 24bit) named sound2. Setting for AVAudioSession as: category (AVAudioSessionCategoryPlayback), options (AVAudioSessionCategoryOptionMixWithOthers|AVAudioSessionCategoryOptionDuckOthers) when playing pcm the sound2 should pushed volume lower as setting. BUT, there has a absolutly mute keep 0.5 second when the sound2 become low, and after a 0.5s mute the pushed lower sound came out. It only become in sound2 situation(192kHz, 24bit). if the sound2's quality lower everything is OK.
