OBC (One Bit Converter) is an hardware emulation inspired by the Motorola MC3518, single bit converters family. It converts digital signal to digital signal by using the single bit conversion emulation.
Principle of single bit conversion
The converter tries to follow an input signal (sample values) by adding or subtracting fixed values.
If the current output sample value is lower than the next input sample value, then an increment value is added to the next output value.
If the current output sample value is higher than the next input sample value, then a decrement value is subtracted to the next output value.
And so on for the next input signal samples.
OBC adds a lot of parameters to precisely drive the converter.
The result of this conversion may sound from a slight frequency exciter to a bit crushed and distorted wave.
