Popping Sound

I have an external USB 3 audio interface called Holo Audio Spring 2 for testing. It supports up to 1,536 kHz / 24 bit audio sample rates natively. I see that there is a chance now to choose this very high sampleing rate in 16 and 24 bit in Audio Midi to get the incoming audio stream upconverted in Core Audio up to this rate. I can get it work in 16 bit but it does not work in 24 bit using my 18 core iMac Pro. To upconvert the same audio stream which works with 1,536 kHz / 16 bit to 1,536 kHz / 24 bit results a distorted sound, using any rates like 44,1 kHz, 48 kHz, 88,2 kHz, 96 kHz, 176,4 kHz, 192 kHz, 352,8 kHz and 384 kHz ( i have audio files recorded professionally with these sample rates) I wonder if it is a bug in Core Audio or it is a bug of the firmware of the USB audio device?Any body has a similar experience? By the way is there any chance to learn what kind of algorthm and noise shaping is used for suc

With the iOS privacy changes I'm a bit confused when we need to show the privacy pop up to request permission, and what needs to be gated behind the answer? We use mixpanel/ga, and from my reading of the iOS 14 documents it seems we may need to ask permission, even if the IDFA is not used. Is this the correct interpretation?

I am developing an application that connects peripherals using BLE. I have a question when the pairing pop up is displayed and is it possible to enable it by core bluetooth or do we need to use External Accessory Framework?. Thanks

Hi, I'm new to AVAudioEngine(and macOS programming in general). I'm trying to mix microphone audio with ScreenCaptureKit audio using AVAudioEngine without playing it back. I've created a AVAudioPlayerNode and scheduling buffers in my SCStream handler: playerNode.scheduleBuffer(samples) and have connected the playerNode to the mainMixerNode. audioEngine.connect(audioEngine.inputNode, to: audioEngine.mainMixerNode, format: micFormat) audioEngine.connect(playerNode, to: audioEngine.mainMixerNode, format: format) The problem is that mainMixerNode plays the audio to the speaker creating a feedback loop. How can I prevent the mixer output from being played back. Also: Is this the best way of mixing microphone input with some other input? I ran into AVAudioEngine's manual rendering mode, which seems like the way to go for mixing audio without playing it back. However, I couldn't figure out how to connect microphone input to the AVAudioEngine in manual rendering mode?

My Bluetooth headphones are cracking and popping. This topic is on a lot of forums but I haven't found any fixes. Some of them are quite old. There is a really long run on this forum in fact years however there's not a fix for me. I did have success with reset the Bluetooth module this morning and it cleared up the distracting noises. I/m back on my computer this ever working in Logic Pro X and it's back. ANY HELP would be greatly appreciated. Thank You in advance. I have a late 2105 iMac Big Sur 11.4 Graphics: ADM Radeon R9 M390 2 GB 32 GB RAM

If one were working on a multi billion dollar project what is the best way to get help and involvement or potential implementations of apple spatial support regarding apple spatial audio support. We are aiming for AES69.

I haven't been able to get peek and pop to work on any XHTML page. Obviously this code will work for an HTML page:<a href=//apple.com>apple</a>But if it's served with Content-Type: application/xhtml+xml, the anchor won't respond to 3D touch. The exact same code served with Content-Type: text/html works tho. Is this a bug?

hiI'm programming in Xcode 9 - swift 4 - macOS NOT IOSI have a basic recording audio setup below for recording a singer with headphones and a microphone. I would like it to react like Logic X.In Logic X you put the track you want to record into record ready while this happens the microphone is routed to the headphones so the vocalist can hear himself/herself. Whilst in playback the record ready is muted so the vocalist can here whats been recorded. and if the record button is pressed during playback then the vocalist hears the vocal being recorded.The problem i am having is routing audio in directly to audio out. I'm not quiet sure what Audio system I should useAVAudioSession is obviously for iOS .Is there anyway i can do this avoiding Core AudioI would like to stick with swift 4Any advice would be appreciatedthanks for reading

the latest beta 13a4325c won't let me create a EarthLink based pop email account on my iPad. It always defaults over to imap, and I cannot convert to pop. any suggestions, other than switching to imap.michael

I created a UISwitch to control the sound. I created it in a view controller named SoundViewController. When I quit the view controller, the sound still playing. That's what I want. But when I open the app, no sound. I turn the switch off and turn it on again then it plays sound. When I turn off the switch, the sound off, and I quit the view controller again and come back, I saw the switch is on but no sound. Anyone please help me? Thanks

How do I show a pop up window to accept data entry without using an alert controller?My idea is to present a view controller as a popover, but I don't know how to manipulate the size.Can someone help me?

I am working with analog medical (eeg) data. I'm trying to allow for recording and scanning large files ~20-30 minutes in length. Core Audio seems like a great solution for storing and playing these files, however the catch is that I do not want to send any sound to an audio device. Everything is output graphically as waveforms. None of my considered solutions seem satisfactory:1. AudioComponentDescription.componentSubType = kAudioUnitSubType_GenericOutput for the output node seems similar to what I want, but since it isn't tied to the timing of a hardware output device, it wouldn't let me play files in real-time at the same speed they were recorded.2. Playing the file with the volume turned down, or with the mixer node disabled is a possibility, but when I tried it I got zeroed out audio playback (logical but unfortunate in my case)3. Having a NSTimer callback repeatedly call ExtendedAudioFile.ExtAudioFileSeek is another possibility, but seems like it is very much not how

I am designing an iOS app which works on sound response.The sound can be of anything. Whenever the user says something or basically when the microphone receives any sound I want to control the phone's flashlight or I want to take any action I want. That should not occur if there is no sound.The approach is simple u say something in microphone flashlight is ON you are quiet flashlight is OFF or u can say if mic recognise any sound coming from anywhere flashlight is ON if no sound flashlight is OFF. Thats it.
