Decrease data usage with Blue hardware
#18
Delta encoding is also simple and no signal is lost Blush 

Example signal from my station:
First row is the raw signal, second row the delta, third row the delta-delta. After the first two samples, 4 bits per sample are enough in this case (not just in this cutout, but in the entire signal). Plus you can still run it through zlib afterwards.


Code:
101        
98    -3    
97    -1    2
96    -1    0
98     2    3
101    3    1
