Hi all,
I am Mynampati Kuldeep Kumar. I am working on MPEG-2 AAC Low Delay Filter Bank. In this it has an algorithmic delay of 20 ms. The reason is as follows

elvi...@hotmail.com - Oct 24 2005
I just tried to use MATLAB to calculate the THD of a generated sine. I found quite a lot of problems.
The sampling rate is chosen at 44.1kHz as same as CD.

Hello,
I have a short question for you.
I am working with blocks of audiosamples which will be calculated like this.

Hi,
I am a new member to this group. I greet every one of you.
I want to find the filter impulse response from the power spectral

Hello All,
Can anyone please help me in writing a C code for dividing a 32 bit fixed
point number by another 32 bit number? I already have a code which works

HI ,
YOu can just follow the Newton Raphson implementation . Just use a small look up and you will be able to do it in 3 iterations.
The equation is x(n+1) = x(n)(3-a*x(n)^2)*0...
