|
|
MEL filters are represented as 3 arrays to encode a sparse matrix.
|
|
|
|
.. autofunction:: cmsisdsp.mfcc.melFilterMatrix
|
|
|
|
The API is returning a tuple::
|
|
|
|
(filterLength,filterPos,PackedCoefficients)
|
|
|
|
The first argument is the list of MEL filter lengths.
|
|
|
|
The second argument is the position of the first coefficient of the filter in the list of coefficients,
|
|
|
|
The last argument is the concatenated list of all filter coefficients.
