Dear Andy, Bill, LF Group,

...>In fact, any sigma-delta  converter is doing exactly this.  And all
codecs in soundcards are SD type.  A sigma delta converter in its
simplest form is a one bit D/A  runing at a very fast sampling rate.

Reminds me of the old DOS era, pre- sound card "Hamcomm" data modes software with its interface, which applied the audio input to a simple zero-crossing comparator, the output of which toggled a handshake line on an RS232 port. In spite of the lack of bits, it managed to generate a reasonable spectrum display, etc.
