Can I get audio input through the GPIO - Raspberry Pi ...
https://raspberrypi.stackexchange.com/questions/4341/can-i-get-audio-input-through-the-gpio
The Peripherals datasheet for the BCM2835, used on the Raspberry Pi, gives you the answer in Chapter 8. I quote: "The PCM audio interface is an APB peripheral providing input and output of telephony or high quality serial audio streams. It supports many classic PCM formats including I2S." 20 pages of information on this subject alone.

Forwarding audio signal through GPIO - Raspberry Pi Stack ...
https://raspberrypi.stackexchange.com/questions/44296/forwarding-audio-signal-through-gpio
The GPIO (general purpos input/output) pins are digital only. That is, they either read digital values (low or high at certain voltage levels) or output such. Audio signals (at least what I read from the question) are on the other hand analogous. The GPIO pins can neither input nor output* such signals in a useful way.
Raspberry Pi - GPIO Connector
https://www.tutorialspoint.com/raspberry_pi/raspberry_pi_gpio_connector.htm
A GPIO pin can be designated as an input pin. The pin set as input pin can be read as 3V3 (high) or 0V (low). You can use internal pull-up or pull-down resistors. You can see in the above diagram, GPIO2 and GPIO3 pins have fixed pull-up resistors but for the other pins, you can configure it …
Raspberry Pi 3 audio input? - Raspberry Pi Stack Exchange
https://raspberrypi.stackexchange.com/questions/43320/raspberry-pi-3-audio-input
To get audio input, the Pi would have to have a dedicated audio codec, which it doesn't. A lot of people mention USB sound cards which can readily be used with the Pi systems. There are other GPIO based sound cards which can also provide input audio lines ... check here for a non comprehensive list. Some of them also have microphones built in or microphone …

Adding Basic Audio Ouput to Raspberry Pi Zero
https://cdn-learn.adafruit.com/downloads/pdf/adding-basic-audio-ouput-to-raspberry-pi-zero.pdf
There is a much simpler way to configure the Pi GPIO pins for PWM audio. Simply adding the following line to your /boot/config.txt will reconfigure the pins at boot without any external software or services: dtoverlay=pwm-2chan,pin=18,func=2,pin2=13,func2=4. Or, you can craft your own DTO 1.
Raspberry Pi Zero Audio Circuit – othermod
https://othermod.com/raspberry-pi-zero-audio-circuit/
The Raspberry Pi is able to create audio using a pair of GPIO pins. The problem is that the audio is badly distorted. The low notes are too low and cause the speaker to rumble and sound blown, and the high notes have lots of unwanted noise. To assist with removing these noises, this audio filter circuit was added to the original Raspberry Pi. An audio filter serves to …
