title: Implementation of FIR filter in C#
body: <p>at the moment im trying to implement a FIR lowpass filter on a wave file. The FIR coefficients where obtained using MATLAB using a 40 order. Now i need to implement the FIR algorithm in C# and im finding it difficult to implement it.</p>
  
  <p>Any help?</p>
  
  <p>Thanks</p>
