Nice, I've been using spek for non-realtime recording checks.

Ffmpeg's multimedia filters can go a long way for visual feedback on live audio. I've been usingffmpeg CLI commands that record audio/video while also displaying a preview with audio overlay for monitoring.

I've only really used audacity for any sort of audio work before.

Is there a short list of the differences between this tool and audacity. Like when would I want to use this tool over importing the audio into audacity.

Genuinely curious, bit of a noob when it comes to audio analysis.
