Same with ambient audio noise?
If a particular band of the GDFT hasn't gone below a certain value in 30 seconds, that should automatically become the noise floor.
I like the idea of "automatic baseline calibration" but I think it's important to address the use case where some music contains prolonged sections of content at a certain volume (or for audio where there is desirable background noise, such as talking in an outdoor environment).
I've just pushed a commit to the 1.1 branch that implements automated background noise removal with this method if you're curious to try it! Essentially:
If Emotiscope hears a note for more than about 10 seconds without the note changing, it grows a small "blind spot" where that bin is, which goes away with about 10 more seconds without exposure to that frequency. Constant hums like traffic outside, A/C units, or microwaves get filtered away even while music is playing, no user interaction needed.
Touch via moving averages has been pushed to 1.1 for anyone curious
If so, touch inputs should be ignored for the first 5 seconds the unit is on to build up the moving average.
