You could never do this on an Apple II. The Apple II hardware was limited to a one-bit click of the speaker (in part due to a dispute between Apple Computer and Apple Records?).
But there was a modem for the Apple II, the Novation Apple-Cat II that contained a tone synthesizer and could be used to play music out over the line. To this day, I think that modem is one of the neatest peripherals ever made:

- Someone 9y agoYou’ll be surprised how far one can push that. https://www.kansasfest.org/wp-content/uploads/Beyond-the-Beep.ppt https://www.kansasfest.org/wp-content/uploads/Beyond-the-Bee... mentions 22 kHz sounds, http://eightbitsoundandfury.ld8.org/software.html http://eightbitsoundandfury.ld8.org/software.html even mentions 44 kHz. It references SAM, a software speech synthesizer that could run on that one-bit click speaker (“with the addition of much distortion”, as Wikipedia says)
- dfox 9y agoFor what it's worth in early 90's people were playing PCM audio on PC speaker, which is single bit DAC that is in turn controlled by programmable interval counter and thus effectively cannot even directly produce single bit PCM. Norton Commander (5 or so) even included PC-speaker WAV player. Edit: also having only one bit can be offset by larger sampling rate. In fact this is how probably every non-audiophile audio DAC manufactured in last 25 years works.
