 If you choose to implement `loadstreaming` and `savestreaming` in your package,
 you can easily add `save` and `load` methods in the form of:
 
-```julia
+```jl
 function save(q::Formatted{format"WAV"}, data, args...; kwargs...)
-    savestreaming(args...; kwargs...) do stream
+    savestreaming(q, args...; kwargs...) do stream
         write(stream, data)
     end
 end
 
 function load(q::Formatted{format"WAV"}, args...; kwargs...)
-    savestreaming(args...; kwargs...) do stream
-        readall(stream)
+    savestreaming(q, args...; kwargs...) do stream
+        read(stream)
     end
 end
 ```
