Increase Spectrogram Scroll Accuracy

Problem

When going up to 40Hz, 30 seconds pass and the data does not hit the 30 second mark.

Expected

30 seconds pass and data always hits 30 second marker in 40Hz, and similar results across sample rates.

Hopefully, we can use something like Java TimerTask to fetch new data from FFT and shift pixel array to the left by one step in a separate thread.
