SwiftAudioPlayer

Swift-based audio player with AVAudioEngine as its base. Allows for: streaming online audio, playing local file, changing audio speed (3.5X, 4X, 32X), pitch, and real-time audio manipulation using custom audio enhancements.

This player was built for podcasting. We originally used AVPlayer for playing audio but we wanted to manipulate audio that was being streamed. We set up AVAudioEngine at first just to play a file saved on the phone and it worked great, but AVAudioEngine on its own doesn’t support streaming audio as easily as AVPlayer.
