“Popping Sound”

I use openal to record and use openal to play ; use QT demo to do the communication. When I put on the Bluetooth headset, as long as I turn on the audio record by BT, the audio playback will be blocked, unable to consume data. And the trumpet is black-color at this time; But when the trumpet is gray, the record will not block the playback,i can play and record . It's a random event。 I wonder if there is a program that can detect or change this blocking?

Hi, I am using Callkit to make a VOIP application recently. But when I use Callkit to make a call out, after the call is connected, I hang up normally, and another call comes in and the following interface appears; Callkit UI error - https://developer.apple.com/forums/content/attachment/3282dcba-263d-4384-aabd-a9b654605858 Callkit UI is not in the foreground - https://developer.apple.com/forums/content/attachment/41cb1f19-7b9f-4c97-b66b-fb320e3e1a5f When I click on the titlebar, the interface will pop up Incoming call ui - https://developer.apple.com/forums/content/attachment/90f37ceb-299e-4c2f-840b-a083ee10e0af This problem can also be reproduced in the SpeakerBox sample code; Model Name: iPhone 7 Software Version: 14.1

I recorded some fan noise using my record app. My audio recording app uses AVAudioRecorder. Recently, I found that audio level is fade in for the first few seconds especially in iPhone 12 series. I tested it using voice memos app too. I checked the same issue. I'm attaching 2 screen shots. One is from iPhone12 and the other is from iPhone11 pro max. Could you explain why this happen? And is there any solution to prevent this?

Hi Community Members, We tried to find the particular sound through the microphone. We used PKCCheck to detect the sound decibel. we detect the sound based on the number of dB values per second we receive and add some logic over it to get the result, but when we have continuous sound like an alarm we can't detect it as the gap between the sound is very less. Any suggestion on libraries to achieve this. Also whether we can achieve this thru Frequency & Amplitude method. Please advise.

My app which was built for iOS12 with videos has no sound in iPad, but has sound in iPhone. The app has sound with headphones on. I tried to unmute and couple of other things. Can someone help as I donot know if it is an iOS issue, code or my iPad issu.

Considering the latest updates added in iOS16 in terms of programmatic navigation, is there a dedicated SwiftUI way of adding the interactive-pop-gesture interaction in the NavigationStack / NavigationSplitView?

I know the VoiceProcessingIO audio unit will create a aggregate audio device. But there are error kAudioUnitErr_InvalidProperty (-10789) during getting kAudioOutputUnitProperty_OSWorkgroup property in recent macOS Monterey 12.2.1 or BigSur 11.6.4. os_workgroup_t workgroup = NULL; UInt32 sSize; OSStatus sStatus; sSize = sizeof(os_workgroup_t); sStatus = AudioUnitGetProperty(mAudioUnit, kAudioOutputUnitProperty_OSWorkgroup, kAudioUnitScope_Global, 1, &workgroup, &sSize); if (sStatus != noErr) { NSLog(@Error %d, sStatus); } And the same code works fine on iOS 15.3.1 but not macOS. Have you any hint to resolve this issue?

in my app, notification has play 20sec sound. i want to stop notification sound when new push notification same thread identifier I tried the methods in the link below https://stackoverflow.com/questions/57568491/handling-remote-push-notification-sounds-when-app-is-terminated https://stackoverflow.com/questions/55324708/how-to-cancel-a-local-notification-trigger-in-swift But I didn't achieve what I wanted Is what I want impossible on OS? Additionally, the sound will only play continuously on the lock screen. If the screen is not locked, the sound is turned off and the sound applied to the new notification is played.

With a 4 channel audio input, I get error while recording a movie using AVAssetWriter and using LPCM codec. Are 4 audio channels not supported by AVAssetWriterInput? Here are my compression settings: var aclSize:size_t = 0 var currentChannelLayout:UnsafePointer? = nil /* * outputAudioFormat = CMSampleBufferGetFormatDescription(sampleBuffer) * for the latest sample buffer received in captureOutput sampleBufferDelegate */ if let outputFormat = outputAudioFormat { currentChannelLayout = CMAudioFormatDescriptionGetChannelLayout(outputFormat, sizeOut: &aclSize) } var currentChannelLayoutData:Data = Data() if let currentChannelLayout = currentChannelLayout, aclSize > 0 { currentChannelLayoutData = Data.init(bytes: currentChannelLayout, count: aclSize) } let numChannels = AVAudioSession.sharedInstance().inputNumberOfChannels audioSettings[AVSampleRateKey] = 48000.0 audioSettings[AVFormatIDKey] = kAudioFormatLinearPCM audioSettings[AVLinearPCMIsBigEndianKey] = false audioSettings[AVLinearPCMB

Hello, I’ve been trying to play system sounds in my app, but this hasn’t really been working. I am frequently switching between speech recognition (Speech framework) and sounds, so perhaps that’s where the issue lies. However, despite my best efforts, I haven't been able to solve the issue. I've been resetting the AVAudioSession category before playing a sound or starting speech recognition (as depicted in the code snippet below), to no avail. Has this happened to anyone else? Does anybody know how to fix the issue? recognizer = nil try? AVAudioSession.sharedInstance().setCategory(.playback, mode: .default, options: []) try? AVAudioSession.sharedInstance().setActive(true) AudioServicesPlaySystemSound(1113) try? AVAudioSession.sharedInstance().setCategory(.record, mode: .spokenAudio, options: []) try? AVAudioSession.sharedInstance().setActive(true) recognizer = SpeechRecognition(word: wordSheet) recognizer!.startRecognition() Thank you.

Could someone please explain how to use a custom sound when setting up an alarm using AlarmKit? It keeps playing a default sound. Also, I keep having an issue where the alarm sound plays but doesn’t show the alarm interface buttons unless the screen is locked.

Our emails contain buttons w/ universal links behind them. Doing a preview (peek) shows the results of sending the link to Mobile Safari. Normally when the button is pressed (or pressing further into the peek--that is, doing a pop) the link is sent to our app.The page rendered by Mobile Safari may/will look different than what the app shows. So the transition from the peek to the pop can be very confusing to the user. This doesn't seem like correct behavior, although I don't know how the peek preview could be handled otherwise.Filed as bug #22870643.
