Arduino has a built-in function for generating tones, and there's a library on GitHub that allows users to expand the number of simultaneous tones that can be played from one to three. However, since the Arduino doesn't come with DACs to generate truly analog signals, both the built-in function and add-on libraries use square waves to generate tones.

Select the Arduino you have connected to your PC in the “Serial Port” drop-down list Then select VirtualMIDISynth in the “MIDI Out” drop-down list If you enable the MIDI Debug messages, you should see the notes played and their velocities scrolling. If the audio output of your computer is activated, you will hear musical notes. N.B.:
Generate Real-time Audio on the Arduino using Pulse Code ...
https://www.maxpierson.me/2009/05/29/generate-real-time-audio-on-the-arduino-using-pulse-code-modulation/
Analog output: The Arduino isn’ t capable of outputting a true analog 0-5V signal. So we’re going to use Pulse Width Modulation, which was intended for dimming LEDs. Now, the default Arduino PWM frequency is 500Hz, which is useless for audio output because it’s much slower than most of the frequencies we want to generate.
The Arduino as a Native Sound Generator – OpenProcessLab
http://bauhausinteraction.org/opl/the-arduino-as-a-native-sound-generator/
Mozzi is another library to generate sounds on the Arduino. It can also be used for sample playback at surprisingly high quality and is even capable of some basic audio processing. The library comes with a variety of examples that demonstrate its potential as a standalone (digital) synth-engine, sampler, DSP or whatever use you can imagine.

Connect power and ground on your breadboard to the Arduino. In the image below, the red (power) and black (ground) wires connect to the two long vertical rows on the breadboard, providing access to 3.3V and ground. Connect a wire from digital pin 2 to one leg of a pushbutton.
Generating high frequency tones - Audio - Arduino Forum
https://forum.arduino.cc/t/generating-high-frequency-tones/103938
void setup () { pinMode (13, OUTPUT); } void loop () { digitalWrite (13, HIGH); // add microdelay or delay here digitalWrite (13, LOW); // and here } by using direct port manipulation and/or timers you can even go higher. If you are talking about generating sinewaves then you need to look at how audio sampling works.
Arduino Sinewave Generator - Arduino Project Hub
https://create.arduino.cc/projecthub/olearyds/arduino-sinewave-generator-10377a
A signal generator usually has various signals that is can generate, such as Sine, Square and triangle. Others have a sweep function and an arbitrary waveform. These are useful tools in the workshop. They can be used to test out audio circuits, op amp circuits and testing circuit response.
tone() - Arduino Reference
https://www.arduino.cc/reference/en/language/functions/advanced-io/tone/
Description. Generates a square wave of the specified frequency (and 50% duty cycle) on a pin. A duration can be specified, otherwise the wave continues until a call to noTone (). The pin can be connected to a piezo buzzer or other speaker to play tones. Only one tone can be generated at a time.
