https://www.sciencedirect.com/topics/engineering/audio-signal-processing
Audio processing covers many diverse fields, all involved in presenting sound to human listeners. Three areas are prominent: (1) high fidelity music reproduction, such as in audio compact discs, (2) voice telecommunications, another name for telephone networks, and (3) synthetic speech, where computers generate and recognize human voice patterns. While these applications have …

However, if you find yourself looking at a cable that’s not labelled, and you’re not 100% sure which type of cable it is, just unscrew the end of the cable and take a look inside. An entry-level audio interface, like the Focusrite Scarlett 2i2, will allow you to record mic, instrument, and line level signals. If you're looking for a more robust recording solution, consider taking a …

amplified audio signal to a small 1.5v - 6v DC motor. It needs to be able. to speed up when the sound is louder, slow down when there is less sound. and stop if no sound. It needs some type of regulator or something to cut. the voltage to a max of 6V DC.
Arduino Audio Input : 8 Steps (with Pictures) - Instructables

The following equation describes the relative amplitudes of the signal before and after the non-inverting amplifier: Vout =~ Vin * (1 + R2/R1) or Vout/Vin =~ 1 + R2/R1 where R2 is the feedback resistor (between the output and non inverting input), R1 is the resistor to ground, Vout is the amplitude of the outgoing signal (the output from the amplifier), and Vin is the amplitude of the …

If you divide your audio signal into sub-bands of much less than one octave width (which obviously requires a low frequency limit for a finite number of bands), then the weighted sum of the instantaneous amplitudes from all the complex signal plus Hilbert transforms of all the sub-bands seems to approach something that looks like an instantaneous amplitude of the …
