64bit?
So does it do 64 bit maths in general or just for addition?
ie if I set a gain slider to -3.012db will it use 64bit logarithms to convert that to a 64bit ratio to multiply the signal by before adding it to other signals?
Just wondering.

by summing I take that to mean addition/subtraction, not multiplication, division, logarithmic calculations.nolus wrote:So does it do 64 bit maths in general or just for addition?

could be interesting to take a sine wave in track 1 and have a bunch of tracks get their input from track 1. bounce all that to 1 track.
Spectrum in track 1 should look like Spectrum in the bounced track, just a spike.
do that in Live 6, take the result into Live 7, compare.

I'm just wondering what the point is of adding signals with 64 bit accuracy if the magnitude of the signal is not accurate to 64 bits in the first place.

plus I'm trying to work out an idea for a mixing system where instead of summing at every point where signals merge, you would just feed forward the gain structure with the original signal and do all the math at the final stage. that way you just add the gain values in db all the way through the chain, and do one log and multiply at the end before summing the result with other signals.

It's bound to have some hit on a 32 bit architecture, but my guess would be that it's negligable compared to the fancy DSP code needed for high quality alias free synthesis and effects. not to mention real-time time streching and complex mode warping.beatpoet wrote:64bit processing is not a addition in L7 that will make me upgrade (like drum racks for instance) but I'm just wondering what kind of a cpu hit does the extra processing give, if any ?
