16F84A One Bit Sound Generation

I found this topic that uses Microchip PIC16F84A Microcontroller as a One Bit Sound recorder and reproducer.

The sound is recorded and regenerated using BTc (Binary Time Constant) algorithm.

The algorithm is designed to be Microcontroller friendly with the minimum Software and Hardware resources.

It's really impressive how you can use only one bit to reproduce digitally recorded sound using simple hardware with small Microcontroller such as PIC16F84A or any other Microcontroller.
