This transistor is low-cost, widely available and sufficiently robust to be of use by experimenters and electronics hobbyists. Maybe you should try to make the supply voltage 5V.
See this page for more info on two stage, and 2n304 transistor amplification. This could be read by the ADC easily into ‘sound level’ without much work at all. Have a look at this. That means it will go to 1V and come back to 0V.

First of all the part with the microphone. Wouldn’t the capacitor do just that, if I then somehow reversed the negative portion of the wave and then smoothed it some? Ehryk 4 11 An AC signal will be centred on the DC bias point. I realize I could easily correct for this in software, but it just seems backward to me in a way and I cannot find any examples of a non-inverting output with a PNP transistor.
The 2N is a common NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications. If it was fully ON, it would be saturated. We have blocked the DC portion of the voltage on the electret microphone.
This is because of tranisstor capacitors.

If this is not the case, can you please explain “I’m not looking for transistof logicthe Arduino’s analog inputs have a bit ADC that gives for 0V-5V, respectively” in this context.
Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site the association bonus does not count. There is no reason tgansistor invert the signal at all. If this is the case you need to state it clearly.
Also, wouldn’t the peak detector vary between Think of a sine wave. I’m looking to simply read the generic sound level from an Electret Microphone. It will generate an AC voltage. Yes, but a diode will drop 0.
2nn3094, notice that there is no more an output capacitor. I understand most of that, thank you. What if we combine the two circuits mentioned above.
But remember, we had some biasing to it which is a DC voltage. You can do this with minor changes to the schematic you have. In order to solve your final question anyway, you have to rectify even with a single diode the output transsitor apply the result to a load traneistor resistor would be fine and feed this to the arduino analog input.
Experiment with different sound levels, for example clap, talk, shout, be quiet, whisper, and see the analog reading changing. If you do not, try lighting an LED if the analog read is higher than, for example,
