Subject: Freq to bark domain From: Vivek Srivastava <vivs(at)VT.EDU> Date: Thu, 30 May 2002 10:47:47 -0400This is a multi-part message in MIME format. ------=_NextPart_000_000B_01C207C7.700E8000 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable 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 ************************************************* Graduate Research Assistant Alexandria Research Institute,Virginia Tech 703-535-3445(Office) 703-582-9456(Mobile) vivs(at)vt.edu ************************************************* ------=_NextPart_000_000B_01C207C7.700E8000 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=3DContent-Type content=3D"text/html; = charset=3Diso-8859-1"> <META content=3D"MSHTML 6.00.2716.2200" name=3DGENERATOR> <STYLE></STYLE> </HEAD> <BODY bgColor=3D#ffffff> <DIV><FONT face=3DArial size=3D2>Hello List,<BR>I have this quick = question to ask=20 about mapping from frequency to bark =3D<BR>domain.
