Guide to configuring FreeBSD as an audiophile audio server: setting up system and audio subsystem parameters, real-time operation, bit-perfect signal processing, and the best methods for enabling and parameterising the system graphic equalizer (equalizer) and high-quality audio equalization with FFmpeg filters. Linux users will also find useful information, especially in the context of configuring and personalising the MPD player and filters.

As a non-audiophile I really enjoyed this dive in to FreeBSD. I use FreeBSD every day but I've never needed to dig in this deep. I really shouldn't be surprised that it was an audiophile that would just keep digging until they got what they wanted. Thanks, most interesting.

@m4c-pl you have a typo there, search for `nemal` :-) You're welcome.

I don’t think I understand the purpose of RTOS here. Why does it improve the audio quality?
I'm curious about why pipewire is unfortunate.
