You've probably used React-Mic before, an awesome React component for recording sound from a user's microphone while displaying a visualization.  However React-Mic only runs on browsers that support the Media Recorder API and the WebM audio format.  

With React-Mic-Plus you get everything in React-Mic, but your audio is created in the WAV audio format which means you can record audio in ANY grade A browser, including mobile & desktop Safari.  Think about this.  Now you can create voice-activated or audio recording Web applications that run in all major browsers and devices - including iOS and Android.  One codebase, every device.
