NE555 pi audio

[liudengyuan]

When we use NE555 as the pulse detector audio generator, its frequency rise is very small. From the beginning of the critical sound to a relatively large frequency, this process needs to raise a very high voltage, so is there a way to make its frequency rise quickly What?

See the Hammerhead project (either 1 or 2) for an example of how to do this.

NE555 need to improve the 10mV voltage, its frequency can improve the subtle rise, there is no way to improve 1mV voltage, its output frequency changes? Please keep the problem
