| Pretty impressive given the limitations, but not very pleasant
| compared to e.g. the C64 SID.

| It sounded similar to this tune:

| nothing else.

| In high school, I built a 1-bit sound board for the Sinclair

| interference as sounds corresponding to program execution.
| Highlight was getting it to play "Yankee Doodle" for a science
| fair. Think I still have it in a box somewhere, will look.

| I also had friends who owned a C64. Someday, a friend let me

| diskdrive!
|
| I was really flabbergasted by that hack!

| Glad to see this topic getting attention on HN! I just finished a
| post about 1-bit music a few days ago:

| boasting about their zx-spectrum with audio, one just don't take
| that sitting down.

| Love the idea of this ... Please lead with the music and then
| explain it. You lost me after the 7th paragraph.

| It's not only the cheapo Sinclair Spectrum that had to make do

| have better sound hardware "out of the box" either:

| The 8088MPH demo also sounds surprisingly good.

| jitter clocks already made for digital electronics.
|
| If you have a multi-bit DAC, it's difficult to made it linear.
| With a 1-bit DAC, it's much easier, because you only have two
| possible output values. And if you run it fast enough, you can
| apply a simple analog low-pass filter to the output and convert
| speed to bit-depth.
