David SomersI 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.
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.

obrhoffJust wrestling with CoreAudio but how should anyone know this?

Thor A. HoplandIt'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.

CVE 2025 31200
Background On April 16, 2025, Apple released a patch for a bug in CoreAudio which they said was “Actively exploited in the wild.” This flew under the radar a bit. Epsilon’s blog has a great writeup of the other bug that was presumably exploited in this chain: a bug in RPAC. The only thing out there that I am aware of about the CoreAudio side of the bug is a video by Billy Ellis (it’s great.
