Hello List,
I have this quick question to ask about mapping from frequency to bark =
=3D
domain. Suppose I have values of a function(say some transfer function =
=3D
of a filter) which are at different frequency samples. I now need to =3D
find the equivalent values in bark scale. I know the conversion of =3D
frequency to Bark scale(used the Traunm=3DFCller equation) but then how =
do =3D
I map these values which I have in frequency domain to bark domain? =3D
Should I just take the average of those values(i.e values which I have =
=3D
in the freq domain) that correspond to each interval in the bark domain( =
=3D
I have taken intervals of 0.2 bark on the z domain i.e one or more =3D
frequency domain values will give me a single value for each interval) ?
Any help in this will be appreciated.
Thanks a lot,
With Best Regards,
Vivek Srivastava
