This adds SPDX license headers to all source code files, following the REUSE[1] specification. This does not include any asset files (such as generated JSON files, or textures). While REUSE does support doing so with ".license" files, for now we define these licences using the .reuse/dep5 file. [1]: https://reuse.software/

## Return Values
|
|
1. @{string}: The event name.
|
|
2. @{string}: The name of the speaker which is available to play more audio.
|
|
|
|
|
|
## Example
|
|
This uses @{io.lines} to read audio data in blocks of 16KiB from "example_song.dfpwm", and then attempts to play it
|
|
using @{speaker.playAudio}. If the speaker's buffer is full, it waits for an event and tries again.
|
|
|
|
```lua {data-peripheral=speaker}
|
|
local dfpwm = require("cc.audio.dfpwm")
|
|
local speaker = peripheral.find("speaker")
|
|
|
|
local decoder = dfpwm.make_decoder()
|
|
for chunk in io.lines("data/example.dfpwm", 16 * 1024) do
|
|
local buffer = decoder(chunk)
|
|
|
|
while not speaker.playAudio(buffer) do
|
|
os.pullEvent("speaker_audio_empty")
|
|
end
|
|
end
|
|
```
