ZL2PD DDS Audio Function Generator
https://zl2pd.com/ddsFcnGen.html
ZL2PD DDS Audio Function Generator This powerful low-distortion audio function generator covers from 1 Hz to above 65 kHz. It produces four different waveforms at low distortion with output levels adjustable from a few millivolts to 5 volts p-p. It's all done with a cheap ATtiny2313 microprocessor and a cheap CMOS 4015 IC. Introduction
DDS Function Generator - Electronics-Lab.com
https://www.electronics-lab.com/project/dds-function-generator/
This is a new implementation of the AVR DDS signal generator v2.0, already published in scienceprog.com. It is obvious that full credit for the original schematic and the firmware goes to its original creator. Presented here is a different PCB that is compact, single sided with only through-hole components for easy construction.

DDS chips are usually aimed at providing a precise low noise frequency source for RF purposes, such as receiver local oscillators. Distortion is a secondary consideration because the output can always be filtered or processed through a PLL.

Audio Sinewave generator DDS using PIC 18F1320
https://www.romanblack.com/onesec/SineDDS.htm
The PIC 18F1320 uses a 10MHz xtal, and generates the sinewave mathematically using a fast 32-bit DDS function. The PIC generates the sine using the internal PWM module. "half bridge" so it actually generates 2 sinewaves (the other is a complimentary opposite sinewave). The PWM sine is filtered using a crude RC filter to become an audio

An Almost Pure DDS Sine Wave Tone Generator - Analog …
https://www.analog.com/en/technical-articles/an-almost-pure-dds-sine-wave-tone-generator.html
The most critical component is the sine wave generator (single or multitone) and here a software-based direct digital synthesizer (DDS) can provide full flexibility with extremely fine frequency resolution and clock synchronization with the data acquisition system to perform coherent sampling to avoid leakage and FFT window filtering.
