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.
STR7/STR9 audio generation with PWM
https://www.st.com/resource/en/application_note/an2394-str7str9-audio-generation-with-pwm-stmicroelectronics.pdf
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
16-bit Audio PWM by Dual 8-bit PWM with Auto …

Bei PWM-Signalen müssen hierbei jedoch sehr hohe Frequenzen gewählt werden, um Audiosignale in akzeptabler Qualität zu repräsentieren. Auch muss das Signal entsprechend nichtlinear vorverzerrt werden, um zu einem letzlich linearen Verhalten des Verbrauchers zu führen. Siehe 1-Bit-Audio.
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.

Possible problems: 1) you "cut" your sound at wrong place. Make fade-out for your PCM audio using some sound-editing software. 2) you switch off PWM. - Don't! To avoid pop you shall run it continuously at 50% duty cycle ("play silence" PCM audio data) …
