The I2S is a small, low cost MEMS mic with a range of about 50Hz - 15KHz, good for just about all general audio recording/detection. The output of a PDM (pulse density modulation) microphone is a 1-bit high sample rate data stream that is the direct output of the Sigma-Delta modulator that's in the mic. Soft rising or falling ramp and analog squelch for 120dB squelch SNR with no pops. In comparison, the ESP32 has way more GPIO, plenty of analog inputs, two analog outputs, multiple extra peripherals (like a spare UART), two cores so you don't have to yield to the WiFi manager, much higher-speed processor, etc. But is also important to point that NO. You can select whether you want it to be on the Left or Right channel by connecting the Select pin to power or ground. MEMs microphone is used which outputs digital I2S signal. I'm trying to get I2S audio working with an ESP32 and WM8978 codec, using the TTGO TAudio dev board. As you can see in the AudioBit pinout, a typical codec will have an I2S bus for audio data and I2C bus for control inputs such as setting I2S data format or configuring the mixing of sound tracks, audio volume… and a LOT of things. ESP32-A1S internal circuit is highly. Developers must then configure the SDK, set the callbacks and also set the I2S audio driver to receive audio data from the digital MEMS microphone. This is hardly new but it allows me to test-run some concepts I want to use in a later project and might help you to get deeper into these concepts as well.
