Not very useful to me.

I can’t get it to accept a file input, and it won’t go when I have an audio playing from a background app.

nice

Its v v useful for voice training or for taking in an audio input into the screen por xeample if i need to encode a raw values into a livn feed i can hook it to a speaker & play it here plus i can more easily see frequencies and their oscillation such as the doppler effect in higher frequencies its very nice <3

Terrific, accurate and tunable spectrogram. So glad I found this one. Nice use of open source library Gaborator.
