由 家住魔仙堡 提交于 2019-11-26 19:21:08
问题 When I set: [[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayAndRecord error:NULL]; …recording and playing works fine, just the playback volume is around 60% lower than when I would just play the same sound without recording and settings PlayAndRecord. I need to get high volume peaks (to check if a user blow in the mic) for that i started a recording session. But without settings AVAudio..PlayandRecord, i can not playback any sounds in the meantime. Thats the reason i

As AudioSessionSetProperty may become deprecated , I'm trying to find an code example of how to route audio to the speaker using other means. Previously I did the following: -(void)setSpeakerEnabled { debugLog(@"%s",__FUNCTION__); UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker; AudioSessionSetProperty ( kAudioSessionProperty_OverrideAudioRoute, sizeof (audioRouteOverride), &audioRouteOverride ); } Trying to get same result but without call to AudioSessionSetProperty . foundry On each release of iOS, more of the audioSession properties are migrated to AVFoundation, so you

AVCaptureSession and background audio iOS 7

由 廉价感情. 提交于 2019-11-26 09:37:43
问题 Whenever I start an AVCaptureSession running with the microphone as an input it cancels whatever background music is currently running (iPod music for instance). If I comment out the line adding the audio input, the background audio continues. Does anyone know a way to record video clips with the microphone while continuing to allow background audio to play? Also there is error, when you trying to record video and the music is currently playing. A tried to do like this: [[AVAudioSession

How to programmatically sense the iPhone mute switch?

由 こ雲淡風輕ζ 提交于 2019-11-26 03:24:10
问题 I can\'t seem to find in the SDK how to programatically sense the mute button/switch on the iPhone. When my app plays background music, it responds properly to the volume button without me having any code to follow that but, when I use the mute switch, it just keeps playing away. How do I test the position of mute? (NOTE: My program has its own mute switch, but I\'d like the physical switch to override that.) 回答1: Thanks, JPM. Indeed, the link you provide leads to the correct answer
