 PortAudio.jl is a wrapper for [libportaudio](http://www.portaudio.com/), which gives cross-platform access to audio devices. It is compatible with the types defined in [SampledSignals.jl](https://github.com/JuliaAudio/SampledSignals.jl). It provides a `PortAudioStream` type, which can be read from and written to.
 
+#### NOTE: This package currently requires the master branch of the `Compat` package.

 ## Opening a stream
 
 The easiest way to open a source or sink is with the default `PortAudioStream()` constructor, which will open a 0-in, 2-out stream to your system's default device(s). The constructor can also take the input and output channel counts as positional arguments, or a variety of other keyword arguments.
