 To that end we start with features supported by popular Rust audio engines like *Kira* & *Rodio*. Requests of those engines also point to needed use-cases. Finally we hope to learn from looking at large projects using audio like *Bevy* and *Fyrox*.
 
 ### Supported by Kira

 - Smoothly adjusting properties of sounds without pops (via [tween](https://docs.rs/kira/latest/kira/struct.Tween.html))

+- Have (partial) functionality on `no_std` targets. Such as capable embedded hardware. The targets need to at least:
+    - Can supports 32 bit floating points through [libm](https://crates.io/crates/libm).
+    - Has 32 bit float atomics via [portable-atomics](https://crates.io/crates/portable-atomic).
+  This would allow applications such as: 
+    - (battery operated) Alarm clocks
+    - Light portable audio players
+  We might make this a soft requirement, meaning we attempt to achieve this if it does not take too much extra effort.
