How to change buzzer tone

[hitsato]

I am using nRF 5 SDK v 14.2.0.

I'd like to change the tone of the buzzer, how can I do it?

I'd like to make the following three settings.
Treble (+ 1 kHz), normal (+0), bass (-1 kHz)

Thank you, everyone.
We will check with the PWM library.
Thank you for your answer.
