hi all

can someone double check my math here on this memory size problem.

i am storing sampled data into memory. the memory is 8M X16 bits.

i am not using all of this memory only from address 0 to 3FFFFF =(4194303)

now i am storing my data in memory unitl it is full. Using a stop watch i timmed 81 seconds until it indicated it was full. However doing the math i am out by a good 14 seconds or so. Just wondering if i am doing something wrong.

4194303 * 16 = 67108848 bits

67108848 / (16 * 44.1khz) = 95.1 seconds.

anyone see an error here?

formula i am using is

memory size = audio seconds * sample rate * no bits used *
 

check my math

Your math looks correct. At a sample rate of 44100 Hz, it takes 95.1 seconds to fill 4 megawords of RAM.
 

Re: check my math

Ur math is coorect
Plz chk that if u have left some memory space as a safe margin for ur full signal,might be due to that u r out of time.
