From dimming LEDs to controlling motor speed, PWM is the go-to solution for power-efficient analog control. This guide explains how PWM works, the relationship between frequency and duty cycle, how to configure it on real MCUs, and practical applications you’ll encounter in production designs.https://toorun.dev/posts/pwm-audio-synthesis-voice-generation-embedded-systems/Mon, 17 Aug 2026 10:00:00 +0000https://toorun.dev/posts/pwm-audio-synthesis-voice-generation-embedded-systems/PWM Audio Synthesis: How to Generate Sound and Voice in Embedded Systems Using Pulse Width Modulation If you have worked with PWM (Pulse Width Modulation), you probably know it for motor control, LED dimming, or switching regulators. But PWM can also generate audio signals: beeps, tones, melodies, and even human voice playback. This technique is common in cost-sensitive embedded products where a dedicated DAC (Digital-to-Analog Converter) is too expensive, too power-hungry, or simply unnecessary.
