Introduction. 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 …

Arduino Code. The 010_BCD_SigGen.c code is implemented using Atmel Studio 6.0. The c-code implements a 24-Bit phase_accumulator of which the higher order 7-Bits are used as an address to a 128 step waveform table containing 6-Bit waveform data with values from 0x00 to 0x1F Hex. Use the 010_BCD_SigGen.Hex to program the Arduino Uno using Avrdude.

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.

https://makezine.com/projects/advanced-arduino-sound-synthesis/
The Arduino is an amazing platform for all kinds of projects, but when it comes to generating sound, many users struggle to get beyond simple beeps. With a deeper understanding of the hardware, you can use Arduino to generate any waveform you can imagine, and manipulate it in real time. Basic Sound Output
Generating high frequency tones - Audio - Arduino Forum
https://forum.arduino.cc/t/generating-high-frequency-tones/103938
If you wanted +/-5V then you need to amplify that signal, or buffer (or amplify) the signal with a part that is powered from +/-5V. system June 4, 2012, 9:25pm #7. So to get 20 kHz we need 40 kHz samples (CDs BTW sample at 44.1 kHz). That is, a sample every 25 mS. Ahem! nickgammon June 4, 2012, 9:50pm #8.
tone() - Arduino Reference
https://www.arduino.cc/reference/en/language/functions/advanced-io/tone/
The pin can be connected to a piezo buzzer or other speaker to play tones. Only one tone can be generated at a time. If a tone is already playing on a different pin, the call to tone () will have no effect. If the tone is playing on the same pin, the call will set its frequency. Use of the tone () function will interfere with PWM output on pins ...
