Lightweight Audio Waveform Viewer

Question

I'm doing a large amount of music library updating and de-duplicating and evaluating, and I would like a piece of software that would allow me to quickly be able to view a waveform of a selected audio file.

I currently use Fission for editing, but it loads slower than I would like, and I have no need for the actual editing aspect of the software. Additionally, Garageband is antagonistically slow and too hard to examine the waveform like I would like.

Is there software, or maybe something like a QuickLook plugin, that would allow me to select an audio file, and quickly get a rendered version of the waveform data within the file?

Loudness levels labels are appreciated, but not required.
