+As mentioned above, [`speaker.playAudio`] accepts at most 128×1024 samples in one go. DFPWM uses a single bit for each
 sample, which means we want to process our audio in chunks of 16×1024 bytes (16KiB). In order to do this, we use
 [`io.lines`], which provides a nice way to loop over chunks of a file. You can of course just use [`fs.open`] and
 [`fs.ReadHandle.read`] if you prefer.
