process audio with an LM393 : harder than it seems ...
https://forum.arduino.cc/t/process-audio-with-an-lm393-harder-than-it-seems/18186
Hi all, I'm trying to use an LM393 as a "positive detector" on two audio signals. I mean that when the audio signal from the pre-amp is above 0 volts the LM393 should produce an arduino-compatible "1" (or "0"). the audiosignal is produced by the pre-amp using a 2.2uF cap in series, so what I get is a pure ac wave without DC bias.

1 Answer Active Oldest Votes 0 The answer is No. Because lm393 can only be used as a sound sensor, it needs an amplifier in order to be able to stream sound. answered Jan 13 '17 at 17:08 subharb 3,152 8 35 69 Add a comment Your Answer Post Your Answer

Audio Amplifiers LM393 R5 resistor construction allows it to adjust the threshold comparator operation – sensitivity. Thus at the exit scheme, we get two logical signal – from right and left of microphones. Also, there is an opportunity to process an analog signal directly from the amplifier through the ADC. J1.
Sound Sensor Switch Circuit Using LM393N Dual …

The heart of this circuit is an LM393N comparator IC. In this circuit, we have used only one out of the two comparators. First, the audio input is taken from the electret microphone. Here a 120nF capacitor blocks the DC component of the audio, allowing only AC to flow to the transistor (2N4401).

LM393 Detex audio class D amp. hi all. it work but have very low power. and + rail mosfet get warmer. i need your helps to solve these problems and power up it to 400w/4R. is this sch better than upper sch? i don't like to use irs2092 because i can't find original ic.2092 expensive. i just like to make class d amp with 494 or 3525 or with op amp.

The LM393 Is a type of comparator IC which is used for making sensors. This IC compares two voltages and currents and gives a digital output of the quantity which is larger.
Can a comparator (LM393) be used as an amplifier ...
https://electronics.stackexchange.com/questions/253109/can-a-comparator-lm393-be-used-as-an-amplifier
An LM393 IS an amplifier but it is designed to be used as a comparator and it therefore is designed to have a very high gain and an open collector output. You could load the open collector output with a resistor to supply and apply feedback (to reduce the gain) so that it becomes a linear amplifier.
