How to generate waveform images from audio files

So what do you display when you need something to uniquely and visually represent an audio file? A useful solution is to display a waveform image, which is a visual representation of the audio file and is presented as a graph of the sound amplitude against time.

Cloudinary's media management service has support for uploading, manipulating and managing all kinds of media files, including images, videos and audio files. You can create waveform thumbnails of audio files just as easily as you can create thumbnails for images and videos, with fine control over the look & feel of the generated waveform image to match your graphic design and the responsive layouts of all devices and browsers.
