avaudiosession

问题 When my Avcapture session is running and ready to record a video , I cannot play and audio files, vibrate or play any haptic feedback? I only found a solution for objective c but not swift. Objective C Solution : Using vibrate and AVCaptureSession at the same time 回答1: As long as you are using microphone in the AVCaptureSession , the haptic feedback will not play. Apple tries to prevent the vibration from disrupting the microphone capture. This is noted in https://developer.apple.com

问题 So my app is running in the background because of CoreLocation that has requested AlwaysAuthorization. This prevents app to reach suspended state. It stays in background state and is receiving location events. After some location events I would like to activate AVAudioSession and play some sounds. How to activate session properly (in this background app) when I'm using other app in foreground right now and this app is playing audio track for example. Suppose I'm watching some video in Youtube

问题 I'm working on an app that does audio recording and playback of recorded audio. I'm using AVAudioSession to change the category to playAndRecord as well as passing it to defaultToSpeaker . My problem is , if I launch the app, play an earlier recording, it plays through the bottom (louder) speaker as I want it to and expected BUT if I launch the app and start recording a new memo then play it back, no matter what I do, it will always use the quieter (phone call) speaker that's next to front

问题 My startRecording function sets up an AVAudioSession for record, which is called on pressing a mic button. Before pressing the mic I am using an AVSpeechSynthesizer to speak some text. If I press the record button before the AVSpeechSynthesizer speech ends that speech is being recorded by AVAudioSession. How do I ignore the speech spoken by my AVSpeechSynthesizer and just record speech speaken by the user through a microphone? 来源： https://stackoverflow.com/questions/61260287

问题 I use AVAudioPlayer to play audio. I have background audio enabled and the audio sessions are configured correctly. I implemented the audioSessionGotInterrupted method to be informed if the audio session gets interrupted. This is my current code: @objc private func audioSessionGotInterrupted(note: NSNotification) { guard let userInfo = note.userInfo, let typeValue = userInfo[AVAudioSessionInterruptionTypeKey] as? UInt, let type = AVAudioSessionInterruptionType(rawValue: typeValue) else {

问题 I'm trying to mimic behaviour as in Phone app during calling. You can easily switch output sources from/to speaker or headphones. I know I can force speaker as an output when headphones are connected by calling: try! audioSession.setCategory(AVAudioSessionCategoryPlayAndRecord) try! audioSession.overrideOutputAudioPort(.speaker) However, when I do that, I don't see any way to detect if headphones are still connected to the device. I initially thought outputDataSources on AVAudioSession would
