STR7/STR9 audio generation with PWM Introduction The purpose of this application note is to provide a hardware and firmware solution to STR7 and STR9 microcontroller users for audio playback of a .WAV file. The approach is optimized in that it uses a minimal number of components external to the
audio - Microcontroller PWM output volume - Electrical ...
https://electronics.stackexchange.com/questions/404199/microcontroller-pwm-output-volume
So I am designing a cheap and simple sound device using the Atmega32U4 uC and stumbled across one problem. I am using the 10-bit PWM output of the uC to output audio and I want the user to be able to control the output volume using buttons, not a discrete potentiometer.

PWM has many use cases in digital signal processing. For our purposes, we will use PWM to vary the average voltage supplied to our Active Buzzer or Speaker. Wiring Up. The circuit to connect a speaker or Active buzzer to your microcontroller is a fairly simple one.
Pulse-width Modulation (PWM) Timers in …
https://www.allaboutcircuits.com/technical-articles/introduction-to-microcontroller-timers-pwm-timers/
This article is the second of a series on microcontroller timers. The first article describes major features of most types of timers and covers periodic timers.. This article describes a more complex timer called the PWM or pulse-width modulation timer. If you are not familiar with the general operation of microcontroller timers, I recommend reading the first article before this one.

2.2 Pulse width modulation (PWM) The PWM modulation transforms the audio input signal interface into digital signals which control the gate of the MOSFET in the power stage at a frequency of about 400 kHz for audio application. The PWM can be implemented either using analog or a digital cells.
PIC sound player (PCM to PWM converter) using PIC18F1320
https://pic-microcontroller.com/pic-sound-player-pcm-to-pwm-converter-using-pic18f1320/
This project makes a PIC microcontroller play audio PCM sounds using PWM modulation! Pulse-code modulation (PCM) is a digital representation of an analog signal where the magnitude of the signal is sampled regularly at uniform intervals, then quantized to a series of symbols in a digital (usually binary) code []. Pulse-width modulation (PWM) of a signal or …
Wave audio player using PIC16F887 microcontroller
https://pic-microcontroller.com/wave-audio-player-using-pic16f887-microcontroller/
The microcontroller generates audio using PWM technique, if the wave audio file is mono (1 channel) the microcontroller will generate only 1 PWM signal (PWM1) and hence we will hear the sound from 1 speaker only. If the wave …
