Bypass compatibliity check if shown Not supportedI worked on adding a new design system, based on Material 3 for the users who don’t like Apple’s design system/Liquid Glass.
I also added a Recorder which uses AAC-ELD (received over AACP*).
This is of much higher quality than the mSBC or CVSD codecs available over Headset/Handsfree Profile where both directions of streams are of poor quality.
This also allows users to use A2DP while recording, meaning high quality playback as well.
I also spent a lot of time digging through AOSP code to understand how the audio system works, so that I can make the AAC-ELD microphone stream available to all apps and calls, and not just for recording from the app.
I also reverse-engineered and implemented the Equalizer that was announced in WWDC26
