How to play an audio in Julia?

While LibSndFile has been updated for 1.3, PortAudio is still in-progress. There are a number of issues with binary packaging that I’ve been working through, but haven’t had time to get it fully wrapped up. It should more-or-less work on the julia1 branch (do pkg> add PortAudio#julia1 but it’s been in-progress for a while.

If you use the Atom editor with Juno (which I recommend in general because it’s a really nice experience for editing/running julia code), then LibSndFile will display as playable audio:

I think you should get something similar if you use Jupyter, though I haven’t tested.

On Linux and OSX, WAV.jl has some functionality to do playback, but I haven’t used it.

If I add “using MFCC” below then I no longer see the sound player, does its use of WAV internally somehow override? I am able to convert to a sampleBuf and then I see the player but I cannot play anything lower than at 3k samplerate, not sure this is a bug or a limitation of the OSX audio engine player through juno.
