To get audio from the digital microcontroller [Mike] built his own R2R digital to analog converter. The resistor ladder is built from sixteen resistors, which feed a rail-to-rail amplifier.

R2R DAC for Oscilloscope Graphics – Ted Myers

0/30/2002If there is more bits in the R2R DAC (like 10?) than bits per sample (like 8?) you could do linear interpolation between samples and increase the sampling rate because then the steps will be smaller and they will happen more often.

High-accuracy 16 bit DAC for Arduino shaduzLABS

This is an R2R (resistor ladder) DAC designed to plug directly onto a cheap Arduino Nano breakout board, and includes a 3W amplifier (using a $1 PAM8403 board) with both headphone and speaker outputs. This is an R2R (resistor ladder) DAC designed to …

Soekris R-2R: Interfacing to an Arduino - Dimdim's Blog

Arduino Audio DAC Options. I compare the 8-Bit PWM DAC with the R2R DAC at various numbers of bits. You might be surprised at how well a 4-bit DAC sounds. As mentioned before DAC is a common short name for Digital to Analog Converter. Basically a binary/digital value is converted to an analog/voltage value. An 8-Bit DAC would convert a
