“Popping Sound”

Hello fellow developers, I am currently working on my bachelor thesis. Therefore my task is to develop a rudimentary solution to stream 2 channel audio from MacOS to an IOS device over Wifi, highest quality possible. Latency is not a major concern, but keeping it low would be great. So i thought of developing something like Wifi2Hifi. That would probably be as rudimentary as possible. I'm not very deep inside the subject. Still researching and collecting thoughts and ideas. If someone could point me to sources and literature on audio related networking/streaming, i would be glad. Also thoughts on networking protocols i could use, or api's etc., would be greatly appreciated. Thanks a lot.

I've been trying to generate a waveform from an audio file without having to play it all.Looks like the only solution is using an OfflineAudioContext but this seems to work on ALL the browsers but Safari. Am I missing something?https://codepen.io/nuthinking/pen/LzQqmP?editors=0010Thanks a lot!

Hello,I'm developing a pre-amp that will accept a music stream over ethernet. On OSX side, I'm writing a driver (just plugin) that will take system audio and send it over ethernet. I'm able to collect the audio data. Now I need to figure out how to stream it out.What is the proper way to do sockets in an audio plugin? I tried using socket callbacks with CFRunLoop but it seems to be freezing all of coreaudiod. Any other suggestion on this architecutre will be appreciated. For example, does anyone see a need for a kernel level driver or will the plugin suffice?Thanks,Konstantin

We've been using remote push notifications from a gateway to allow us to provide auth information. In some cases there's no sound to tell the user that a notification has arrived. In our code we specify UNAuthorizationOptionSounds, and the notification settings on the devices are set to allow notifications and sounds for the application. The client code hasn't changed in a couple of years, so I'm wondering whether something might have happened from the sending side. That's not my strongest area though. Does anyone know whether there could have been a change in the call generating the push notification which cut off the sound, and where I would look for documentation on that?

i want to add vibration and sound with the notification on iwatch, when it arrives on apple watch. I dont know how to do it. Currently my notifications are being displayed on apple wtch but without any sound or vibrations. I want to add these stuff with the notification.

Hello,We are trying to send compressed audio data over BLE.Our test setup includes a Linux PC(Peripheral) and an iPhone acting as the Central.We have the below characteristics on the Peripheral for audio transfer.Char1 (Read | Notify)Char2 (Write)We have an use case where audio transfer happens both ways simultaneously using these two characteristics.Peripheral -> Central (using Char1)Central -> Peripheral (using Char2)The Peripheral -> Central transfer seems to be fast enough for audio playback.But with the Central -> Peripheral transfer, we see a considerable lag.This transfer takes more than double the time required for Peripheral -> Central transfer.We also tried sending a connection parameter update request to set the connection interval between 20-21ms.But still we see no increase in the transfer speed.Are we missing out something here that enables faster transfer rates when sending data from the iPhone to PC?

Whenever I get a notification, it lowers the audio that I’m currently listening to at the moment. Everywhere I look, the answer I see is just to mute my phone or put it on do not disturb, but I still wish to hear the ringer go off when I get a notification. is there a way I can stop the audio from lowering without needing to mute the ringer?

Some of our clients that have updated their devices to iOS 11 have reported that they are not receiving any sound or vibration when receiving notifications, after testing myself I can confirm that this is the case. The notification is constructed on our API with ping.aiff as the value for sound like so:string appleSound = ping.aiff;var appleNotificationMessage = ${{aps:{{alert:{message}, sound:{appleSound}}}}};I've tried to search around a bit but I haven't found anything, any ideas why this may have stopped working? Notifications are coming through fine they are just silent and as far as I can tell the notification settings on the app are fine.

Hello, I started to set audio stereo recording (both audio and video are recorded) and the audio quality seems to be lower than quality obtained with native camera application (configured for stereo). Using console to check the log, I found a difference between camera app and mine regarding MXSessionMode (of mediaserverd) in fact, camera application gives MXSessionMode = SpatialRecording and mine MXSessionMode = VideoRecording How can I configure capture session to finally have MXSessionMode = SpatialRecording? Any suggestion? Best regards

Hi all, I am developing a digital signal processing application using AudioToolbox to capture audio from an audio loop application (BlackHole). Environment: MacOS Sonoma 14.4.1 Xcode 15.4 Quicktime 10.5 (I also tested with JRive Media Center) BlackHole 2ch and 16ch Problem: All audio samples received are zero. Steps to recreate: Set Mac Settings Sound audio output to BlackHole 2ch. Set Mac Settings Sound audio input to BlackHole 2ch. Authorise Xcode to access Microphone. In Audio MIDI set Use this device for sound input and Use this device for sound output. Set volume of both to 1.0 . Play a 44.1 16-bit signed integer stereo FLAC file using Quicktime. Start C++ application . Key details of my code below... AudioStreamBasicDescription asbd = { 0 }; asbd.mFormatID = kAudioFormatLinearPCM; asbd.mFormatFlags = kLinearPCMFormatFlagIsFloat | kLinearPCMFormatFlagIsPacked; asbd.mSampleRate = 48000; asbd.mBitsPerChannel = 32; asb
