iOS Audio Waveform Rendering using the Accelerate Framework

This is a presentation that I gave in August 2017 to the Tokyo iOS MeetUp Group.

The code shown here is Objective-C and I have since re-written this in Swift 4.0. While doing so, I also changed and refined a lot of the code with the intent of speeding up the code even further.

The outcome of that effort will be posted here in the very near future.

I have not written up a new presentation yet so I will make some notes on my email to you on anything important that has changed.
