# Aerials Audio System

A `miniaudio` binding for `Defold Engine`.

Only APIs used in `Aerials` are implemented. **Refer to** `api/acaudio.script_api` **for API usages.**

***Note**: If you want to bundle a `Windows Application` with this extension, you may need to put a valid `MSVCRT.lib` file into the `lib/x86_64-win32` directory.*

---

### Example

You should implement your HitSound system **with a Unit Pool** like this:

```lua
local CreateUnit = AcAudio.CreateUnit
local PlayUnit = AcAudio.PlayUnit

-- Create the HitSound Unit Pool (some_src is created from AcAudio.CreateSource)
--
local HitSoundUnits, UnitCount
local FirstUnit, UnitLen = CreateUnit(some_src)
if FirstUnit then
HitSoundUnits = {FirstUnit}
--
-- Choose a reasonable filter interval,
-- And set the UnitCount according to it.
--
UnitCount = math.ceil(UnitLen / 50) -- Filter Interval: 50ms
UnitCount = (UnitCount>1) and UnitCount or 2 -- Use at least 2 Units
for i=2, UnitCount do
local u, l = CreateUnit(some_buf)
if u then
HitSoundUnits[#HitSoundUnits+1] = u
end
end
UnitCount = #HitSoundUnits
end

-- Encapsule the Playing Method with the Unit Pool Created above
--
local Which = 1
local function hit()
PlayUnit(HitSoundUnits[Which], false) -- Play the HintSound only once
Which = (Which==UnitCount) and 1 or (Which+1) -- Update the counter
StopUnit(HitSoundUnits[Which], true) -- Let the next Unit rewind to start
end
```
