Audio Units for DAWs
Hello all,I've been working with custom AudioUnit for AVAudioEngine on iOS for a while (Audio Unit v3), and I now want to build an Audio Unit plug-in for macOS DAWs (Logic Pro or Ableton Live for example). I've been looking about the subject for a while, but I can't manage to understand how it works.It seems that part of the solution is Audio Unit Extensions, as I saw in WWDC 2015 - 508 and WWDC 2016 - 507, but I don't get how I can reuse the .appex product in Logic Pro or Ableton Live. I've used 3rd party audio units for these softwares but I always get them as .components bundles, which is to be copied in the /Library/Audio/Plug-Ins directory. I tried to copy the .appex in the same folder but it doesn't seem to be recognized by Logic Pro.Any idea about what am I missing here?Thank to you all 🙂Tom

Reply to How to show/hide Now Playing button on CPTabBarTemplate
Hi, The system automatically shows the now playing button in the tab bar and nav bar when your app becomes the now playing app, and hides the button when another app starts playing audio. You are correct that, in order for the now playing button to show AND for now playing to populate with metadata, your app must start playing audio. In general, if your app is playing audio at the time when it's launched on the car screen, it's a best practice for your app to present its root template (e.g. a tab bar template) and then immediately push the now playing template on top. This is also done on behalf of your app if the user launches your app by way of the system 'Now Playing' icon on the CarPlay home screen. Also, is there a way to hide the Now Playing button after the queue of content has finished playing? I'm able to pop the Now Playing template, but the Now Playing button is still present and tapping it will navigate the user to the now blank Now Playing template. Not current

USB Audio Failing
I've observed USB audio seems to fail in El Capitan Developer Preview 1 using a CEntrance HiFi-M8. This device supports a range of 2 channel 24 bit formats (44.1KHz, 48.0KHz, 88.2KHz, 96.0KHz, 176.4KHz, 192.0KHz, etc.). While it worked just great in Yosemite, what seems to occur now is a grainy/garbled sound that seems a bit like the wrong format is being played even when 44.1KHz is selected in Audio MIDI setup and a 44.1KHz file is played in iTunes or in Safari.

Ducking and Un-ducking Audio
So I am working on an app that requires audio files to be played intermittently and it should duck audio coming from the background...(such as music from iPod or Pandora). I understand that you need to activate your audio session, then upon completion of the audio playback, you deactivate the audio session to get the background sound to return to its normal volume. My only problem I am having is that when there is no background audio playing, and the audio session is not active, the volume buttons on the side of the phone control the ringer volume and not the app audio volume. This is a problem for me, because I would like the user to be able use the volume buttons to control the volume of the upcoming audio alerts at all times. When the volume buttons are controlling the ringer, the user has no control over the app audio / alert volume. I know of at least two fitness apps in the app store that are able to duck

listening to the Sound while recording?
Ive got a 13 pro max, and I wonder if apple forgot that function of hearing the sound in the headsets while recording. Not just afterwards playing it, which takes time. Plus doing documentary film its not always possable to do a second simullar recording, if the sound is bad. Do anybody know what to do?

Siri Without Sound
Today I was going to use Siri on my iPhone 5C and I found out something: There are no sounds, not even Siri's voice. That's something strange because in my iPad Mini 2 there are all Siri's sounds. Anyone else experiencing this?

NowPlayingInfo for video and audio
In my tvOS App I play video with the AVPlayerViewController and use the externelMetadatafor providing Info to the NowPlayingInfo.I also play audio with the AVQueuePlayer and my custom UI. For audio, I set the infodirectly to the MPNowPlayingInfoCenter.When i run my app an play some audio first, the NowPlayingInfo is displayed correctly.Then I play a video and the NowPlayingInfo is also displayed correctly.But after presenting a video with the AVPlayerViewController, the playback of audioand setting of the info via MPNowPlayingInfoCenter no longer works. I also noticedthat in the Remote-App the NowPlayingInfo still shows the info from the last video.Prior to the tvOS 11 version everything worked as expected. I could play audio andvideo in any order and the NowPlayingInfo was always showing correctly.Is this a bug of tvOS 11 or must i do something else?Thanks.

iOS 9 audio
I have a published app where the record and playback worked fine. Recently I upgraded to iOS 9. Now the record and playback works sporadically - like one time in ten tries. Using AVAudioSession, AVAudioRecorder, AVAudioPlayer.Normal functioning is that during playback the other sound-related buttons (such as record) are made inactive/grayed out for the few seconds duration of the playbackCurrently, when you record (or attempt to) and playback fails, the sound-related buttons are inactive/grayed out and just hang in that stateOther audio-related actions in this module (such as playback of pre-recorded narration of the verse) continue to function as expectedI used the record-playback function at least as recently as December 1 and it was working fineI am at a loss as to how to proceed to either investigate or repair the problem.I have at least one friend who has also had audio issues with iOS 9. Is there a bug here? Is Apple working on it? Is there a reason to just wait for A

Audio from HomeKit Camera
Hi, I'm trying to play audio from my HomeKit camera, but can't figure out how to do it. The only documentation I can find is from WWDC when they show you how to play video in an HMCameraView. But how do I get the audio to play in my app? Thanks a lot in advance!
