## How to build?

Please install [CocoaPods](https://cocoapods.org/) dependency manager on your Mac.

```
git clone https://github.com/romankisil/eqMac2.git
cd eqMac2/

open eqMac2.xcworkspace
```
And then ⌘R

## How it works

I basically took Apple's [CAPlayThrough example](https://developer.apple.com/library/content/samplecode/CAPlayThrough/Introduction/Intro.html) and modified the AUGraph to have an EQ node. Combined it with [SoundFlower Audio Driver](https://github.com/mattingalls/Soundflower) and it just worked.
