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.

SoundSourceのようにアプリ別にサウンドを出力するオーディオデバイスやボリューム、EQを設定できるMac用オーディオコントローラー「FineTune」がリリース。

Just wrestling with CoreAudio but how should anyone know this?

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.

macOS 26 TahoeにアップグレードしたMacで、スピーカーからパチパチというクラックリング/ポップ音がする不具合は一部Xcode/iOSシミュレーターが関係しているもよう。

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.

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

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?

@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.
