  • shairport-sync

    AirPlay and AirPlay 2 audio player

    This looks cool. I'm not sure if they are intending to go all the way to room correction but it can really do wonders. A good while back my music setup used filters calculated by an open source FIR tool with playback driven by an older version of Shairport (emulating an AirPort express) using BruteFIR as a convolver. Fiddly to set up but it sounded really good.

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • AutoEq

    Automatic headphone equalization from frequency responses

    Yes, but no, but yes.

    AutoEq (https://github.com/jaakkopasanen/AutoEq/) does something like this so... yes?

    But targets various HRTF curves which aren't neutral or flat, and they usually aim for a Harman target of sorts, so no...

    But there are some neutral-sounding curves that seek to just emulate pinna gain, so they have a ~3KHz peak which is required to 'emulate' the natural resonance of your ear, which you don't get naturally when you jam a driver all the way into it.

    There's no AutoEq preset for the AS06s. Here's a representative sample targeting the 2019 Harman in-ear target for the KZ AS10s for funsies though: https://github.com/jaakkopasanen/AutoEq/tree/master/results/...
