If a signal with an amplitude of less than or equal to the maximum permissible value is bitshifted by one to the left (i.e. multiplied by two) then the resulting signal has no (further) added noise. This will have a side effect of making all of the lowest significant bits equal to zero.

QUOTE (Nick.C @ Jul 10 2008, 10:12)  If a signal with an amplitude of less than or equal to the maximum permissible value is bitshifted by one to the left (i.e. multiplied by two) then the resulting signal has no (further) added noise. This will have a side effect of making all of the lowest significant bits equal to zero. My ignorance is a LOT deeper than AndyH-ha's. So I ask: Does this mean that if you have a 24-bit recording, with the "top" 8 bits unused (because it's been left for headroom, or whatever), you can losslessy convert it into a 16-bit recording, using all the bits? If the question in itself betrays hopeless ignorance, please be gentle and just refer me to the right part of the Wiki or whatever; I only ask because I think it relates to what's at issue after ccryder's posts. |
