Fast 1D DCT Implementation in C/C++

[Soumyadip Rakshit]

Hi,

Could anyone direct me to a very good 1D DCT Implementation in C/C++

My data is in sets of 8 numbers.

Thanks a ton,
Soumyadip.

I suggest you search diligently for a newsgroup that deals with the
"C/C++" language. After you find such (nobody here ever heard of
it, and I know of no ISO standard for it) check whether that
languages standard mentions anything like a "1D DCT
Implementation".

This group deals only with the C language, as described by the
various ISO standards and their predecessors.

"Very good"? Does that mean "very fast"?

If so my recommendation is
