How to obtain Mel Filterbank?












-1















What is the logic behind the calculation of Mel filterbank? Is there any good example for it ? I could not find any good example on internet.

You can find a really nice tutorial on how to obtain Mel filter banks here.



In general, we use Mel filter banks for two main reasons.




  • The Mel scale aim to mimic non-linear human ear perception of sound. Human ears are more discriminative at lower frequencies and less discriminative at higher frequencies. Mel filter banks do exactly that by giving a better resolution at low frequencies and less at high.

  • Triangular filter banks help to capture the energy at each critical frequency band and roughly approximates the spectrum shape. This also helps to smooth the harmonic structure.
