The truth about bit-depth (and digital audio ‘resolution’)

[Etienne1973]

Does binary keeps information partially intact when truncated instead decimal looses info completely?

For Example:

24Bit word truncated to 16Bit

1011 1111 0101 1101 1010 0110
____ ____ 0101 1101 1010 0110

decimal number truncated

1'200'377
120'037

"truncated decimal" would rather be 200377, not 120037. truncation starts from the top.

When I look at my example I can see a portion in binary looks still the same (so intact partially) but in decimal the number is a completely different after shortening.

that's because you did the truncation wrongly. you truncated binary from the top, but you've truncated decimal from the bottom. if you truncate it from the top, just like you do with binary, you'll keep "a portion of the information".

what you did:

1'200'377
120'037

what you should have done:

1'200'377
'200'377
