Awwdio is the name of FrooxEngine's audio system.
Etymology
The name “Awwdio” was revealed by Frooxius during The Resonance EP14.[1]
The inside of the human cochlea has about 3,500 tiny hair cells that sense vibrations and send electrical impulses to the brain. In order to hear, your ears literally have to be furry on the inside—hence the “aww” in “Awwdio.”[2]
Implementation
Awwdio is responsible for mixing audio sources, and directly integrates Steam Audio for spatialization.[3] It also integrates Zita Reverb for reverb effects.[4]
The system is heavily multi-threaded, and makes use of lock-free concurrent audio mixing, which means it's very performant.[4]
You can change the output buffer size and simulation buffer size on-the-fly, which allows for finding a balance between latency and audio-stability (fewer crackles).
