[ANN] WaveFlow.jl: Audio engine in Julia

[Gesee]

Hello guys.
I present my new package WaveFlow.jl, a complet audio engine.
I’m not an audio engineer but I think it’s pretty good
Here are the available features:

• File loading: Waves can load a wide variety of format such as ogg, wav, mpeg and soon mp3
• Streaming: Waves use a circular buffer to let you play long audio without comsuming too much memory and processing power.
• Groups and Bus: Waves let you create sound groups and sound bus for more granular control over you sounds
• Mixing: You are not limited to one sound at a time.
• Configurable: You can manage volume, panning, pitch, speed as you want.
• Effects: Add reverb, equalizer, compressor or even you custom effect on your sounds!
• Metrics: Track CPU usage, signal peaks, and more — updated in real-time
• Real-time audio: Powered by PortAudio for low-latency playback

Hope you will enjoy using it.
The package is being registered but you can still take it as a development version

Thanks @Gesee ,
Great to see some new activity on the audio front!

A few friendly comments from an initial testing:

• It looks like you changed the interface since writing the documentation:
  This line gives an error:
  sine = generate_sine_wave(frequency=440.0, duration=3.0, amplitude=0.5)
  but this works: sine = generate_sine_wave(440.0, 3.0). I think you should just go with the keyword arguments as in the docs.

• Could you please add an option to choose the device in WaveFlow.jl/src/core.jl at 75c6fb77e7d7c2450db3c227835c5c2ef3b0ceee · Gesee-y/WaveFlow.jl · GitHub.
  I’m not getting any sound out of device 1.

Looking forward to doing some more testing!
