.NET, C#, Signal Processing, and add FFT (HP,LP,BP or BE filter)

We have a project that uses the FT (which works fine, but is slow) and takes in an array from a WAV file and outputs the same array(16 bit) as a filtered WAV file (HP, LP, BP or BE). This is in C# and can be provided. We want a new routine (with the same IO as the existing one, and so can be used in its place) that uses a good FFT. The FFTW is a free download and would be suitable.

Also we would like software that would produce an envelope output from the same WAV file and output it as a WAV file but at a lower sample rate. It should have the same IO as the above FFT.

Later there could be additional filter related requirements.
