PWM with AtTiny85 - Audio - Arduino Forum
https://forum.arduino.cc/t/pwm-with-attiny85/182466
scswift: Supposedly the sound quality is higher that it would be with a typical Arduino because the AtTiny has faster PWM. I'm afraid the ATTiny AVR is no faster than an Arduino (which uses the Atmega AVR). If I understand correctly, this is because the AtTiny can do PWM at 64mhz. If you mean millihertz, then sure, that's pretty slow.

Tiny basic PWM. The ATtiny85 microcontroller allows us to generate an analog output using PWM. The ATtiny85 microcontroller has two timers that can be used to generate PWM signals. The first is Timer 0, an 8-bit timer capable of phase-correct and fast PWM used for functions such as delay() and millis().
Technoblogy - Four PWM Outputs from the ATtiny85

Four PWM Outputs from the ATtiny85. 7th July 2014. The ATtiny processors allow you to generate an analogue output using Pulse Width Modulation (PWM). One or more counters in the chip allow you to generate a constant-frequency square wave and specify the proportion of the time it's off and on.

Pulse width modulation aka PWM is a popular digital modulation mostly used in controlling motors, lights, power supplies, heating devices etc. ATtiny85 has in built feature to generate PWM signal of variable frequency and duty cycle. This PWM generation by ATtiny85 is possible using timer (tutorial here ) and compare match module (tutorial here).
