#coreaudio — Public Fediverse posts

My audio pipeline can use either #CoreAudio or #FFmpeg or #libopus for codec purposes. The biggest shock was realizing that using pipes is a lot easier than an API, and that thinking like #plan9 isn’t as crazy as it first seems.

Using #PortAudio to send PCM on my Mac was causing a few problems, so, I whipped up some #golang to talk to #CoreAudio via CGO and now everything is nicely going beepboop. And I’m discovering that using go to generate sfx, music, and tts is kinda fun.

I did a bit of #AudioDev for the past few days, but eventually I finally got my pipeline to work. I have mixed feelings about demuxing a html stream, piping aac/mp3 across #FFmpeg to get PCM, doing some manipulation (because FFTs are fun), then calling #PortAudio to call #CoreAudio to make the speakers go beep-boop.

Apple Patches 2 Exploited iOS Zero-Days in CoreAudio and RPAC

It's absolutely amazing how far #wine has come. In combination with an rt #Linux kernel and #yabridge, I've gotten some hefty #VST3 plugins to work quite well.

Not to mention that #PipeWire is giving #CoreAudio a run for its money.

It's now possible for me to move over to Linux as a music workstation - and you should too.

Follow me on further #LinuxMusic adventures!

CVE 2025 31200 #Apple #CoreAudio #vulnerability analysis 🤯

https://blog.noahhw.dev/posts/cve-2025-31200/

The brilliance of #PipeWire is that it's a standardized media routing graph. What does that mean?

One one the reasons both #Android and #Windows suck is how they implement audio servers. #macOS & #iOS has them beat, purely by how well standardized #CoreAudio & #CoreMIDI are.

But, do you want one interface to access web cams, screen grabs, encoders, DMX controllers, as well as MIDI & audio devices - in preemptive real-time?

If so, PipeWire is the perfect option, for the studio - and media IoT.

Breaking the Sound Barrier Part I: Fuzzing CoreAudio with Mach Messages

@nielso I also find #pipewire to be better than #coreaudio on macOS.
Many of the things I used to do on macOS with some helper apps, I now do out of the box on #linux.
And yes, in many of the "polished" apps that are used on Windows or macOS, I think a lot of the complexity (but also flexibility) is probably kept away from the users, which may lead to small successes faster, but doesn't necessarily promote the underlying understanding of what's actually going on, if that makes any sense.

So this is a fun #Audio tool for #macOS if you listen to various #HiRes and/or #LosslessAudio formats and want to switch a digital output to the matching #SampleRate on playback - https://github.com/vincentneo/LosslessSwitcher

I'd love for it to match discrete output channels and bitrate along with sample rate to account for multichannel source material 🤔 I may have to play with the #CoreAudio tricks they use for the app.

CoreAudio and AirPlay don't exactly seem like a match made in Heaven. Does anybody know how to detect inactive AirPlay devices? Retoot appreciated. #Swift #macOS #CoreAudio #AirPlay

My RME UCX audio interface has died after 11 years of service. I’ll probably replace it with the UCX II, but I’m interested in alternatives. Arturia’s AudioFuse 16Rig looks suitable for my studio (mostly line level, some synths & CV, a couple of mics) but it uses the default Core Audio driver (on Mac). Is that good enough?

What other audio interfaces do people recommend?

#MusicProduction #Recording #Arturia #RME #CoreAudio #AudioInterface #Soundcard

@PatrickOBeirne Yes! I just wrote up my findings so far and asked on the Apple forums: https://developer.apple.com/forums/thread/763325 - hopefully the code examples will help identify the issue.

Just tagged #libASPL 3.1.0

Release includes better support of overriding low-level I/O handlers with your own and numerous bug-fixes.

👉 https://github.com/gavv/libASPL/releases/tag/v3.1.0

#macosaudio #coreaudio #audioprogramming

New on the blog: Modern CoreMIDI Event Handling with Swift:

Let's say you have some number of people you regularly invite to A Thing. How do you manage the list and the invitations? I've been using a google form and a bcc email but I'd rather do something nicer if it exists.

EDIT: this is a regular event, what I send is less invitation and more reminder. A handcrafted artisan email with an entertaining gif and the exact time and date.

It's Karaoke. I am slowly bringing back #CoreAudio and it's been so long I thought I'd see if it was easier now.

Tagged #libASPL 2.0.1 https://github.com/gavv/libASPL

Changes:
* users don't need Jinja2 now (code generation excluded from build)
* fixed warnings
* fixed typos

libASPL is a C++17 library that simplifies creating macOS virtual audio devices.
