analog audio in to PWM audio out - Audio - Arduino Forum
https://forum.arduino.cc/t/analog-audio-in-to-pwm-audio-out/139411
it takes in audio on ADC0 and uses a dual pwm to create 16b audio out. you can process the audio in-between and make a low-fi effects pedal. it can be used for just analog out as well, and is much higher quality than using analogwrite (although more complicated too). there is a much more in-depth tutorial on pwm in general up here:

https://electronics.stackexchange.com/questions/257958/how-to-use-pwm-with-an-arduino
I bought a trrs audio jack breakout and i tried to use this using arduino. I connected the tip to an analog output (I made a pwm to analog converter), I created program on arduino that send 10% voltage in the pwm and I heared a sound but it didn't changed when i changed the voltage(for 10% to 9%, 11% etc).

Arduino Audio Output: Generate sound or output analog voltages with an Arduino. This Instructable will show you how to set up a really basic digital to analog converter so you can start generating analog waves of all shapes and sizes from a few digital pins on an Arduin…
TOPIC: Configure Arduino UNO PWM outputs to play audio.
https://www.electrosmash.com/forum/pedalshield-uno/111-configure-arduino-uno-pwm-outputs-to-play-audio
In a nutshell, this is what do you need to know/do to configure the Arduino Uno PWM output to play analogue signals or audio: Combining PWM outputs: In Arduino UNO each PWM output has a resolution of up to 8 bits, so you can use one, two or even three PWM outputs to generate the output signal. pros: higher bit resolution and lower noise floor.

PWM stands for Pulse Width Modulation and it is a technique used in controlling the brightness of LED, speed control of DC motor, controlling a servo motor or where you have to get analog output with digital means. The Arduino digital pins either gives us 5V (when turned HIGH) or 0V (when turned LOW) and the output is a square wave signal.
Line level audio output from PWM? : arduino
https://www.reddit.com/r/arduino/comments/bnk6bg/line_level_audio_output_from_pwm/
Line level audio output from PWM? As with my last few posts here, I'm working on a homebrew computer conversion for the Mega 2560. Looking at Secrets of Arduino PWM, it seems that some of the PWM modes can natively work as sound chips, without screwing around with analog filters or resistor DACs. Set the COMxA bit to 0 instead of 1 and you can ...
Arduino PWM output and its uses - The definitive guide
https://technobyte.org/arduino-pwm-output-uses-generation-control/
Is the Arduino PWM output analog? The Arduino doesn’t have a built-in digital-to-analog converter (DAC). The ‘analog signals’ are, in reality, pulse width modulated digital signals. You can use the inbuilt function, analogWrite(pin, value), to give a PWM output signal.
Smoothing PWM output - Arduino
https://forum.arduino.cc/t/smoothing-pwm-output/3529
A friend and I are working on an amp, DIY LM3886 Chip Amplifier (Gainclone) Kit this is it. It is 6 channels, and obviously all channels having to have the same value for Rin so I suggested using a similar approach to a lightspeed attenuator except having the LEDs pulsed by the PWM output on the Arduino and having the PWM output smoothed with some caps, has …
PWM Output Problem - Project Guidance - Arduino Forum
https://forum.arduino.cc/t/pwm-output-problem/304298
system April 12, 2015, 3:46pm #1. Hello Arduino forum, I am running a basic servo sweep function (the one provided on the website) and pin 9 of my Arduino Uno isn’t outputting a PWM signal. I hooked it up to an oscilloscope and found that it is outputting a constant 3.3V. All of the other PWM pins on the Uno are working properly.
