 ### Usage
 
 1. Import `SimplyCoreAudio`
-	```swift
-	import SimplyCoreAudio
-	```
+    ```swift
+    import SimplyCoreAudio
+    ```
 
 2. Instantiate `SimplyCoreAudio`
-	```swift
-	let simplyCA = SimplyCoreAudio()
-	```
+    ```swift
+    let simplyCA = SimplyCoreAudio()
+    ```
 
 3. Interact with `SimplyCoreAudio`
-	```swift
-	// Get the default output device
-	let device = simplyCA.defaultOutputDevice
-
-	// Get preferred output channels
-	if let stereoPair = device.preferredChannelsForStereo(scope: .output) {
-		let leftChannel = stereoPair.left
-		let rightChannel = stereoPair.right
-		// Use channels...
-	}
-
-	// Get device samplerate
-	if let sampleRate = device.nominalSampleRate {
-		// Use samplerate...
-	}
-
-	// Get device virtual master volume
-	if let outVolume = device.virtualMasterVolume(scope: .output) {
-		// Use output volume...
-	}
-	```
+    ```swift
+    // Get the default output device
+    let device = simplyCA.defaultOutputDevice
