-/// The new hot thing: this represents audio in any format. You can open any file and make this thing with the file's bytes.
-/// You can then modify its bytes and see what it gives. Maybe it won't work anymore.
-/// You can also decode it to raw samples and play with it freely without corrupting anything.
+/// Audio, unlike DynamicImage, isn't directly bendable
+/// because its underlying data format isn't decided automatically
+/// so you have to attribute it yourself by turning it into a [RawSamples] struct
+/// with your chosen sample format.
