@ -14,7 +14,7 @@ This function takes in the binary data from a WAV file, and outputs a more
usable table format with all the metadata and file audio inside. It also has a
[`readWAVFile`] function to simplify reading from a single file.
@see cc.audio.play To play the chunk decoded by this module.
@see speaker.playAudio To play the chunks decoded by this module.
@since 1.113.0
@usage Reads "data/example.wav" into a table, prints its codec, sample rate,
and length in seconds, and plays the audio on a speaker.
