References for the BARK/MEL stuff
Could someone point me to the BARK/MEL tables that these macros (from vorbis/scales.h) are trying to approximate?
#define toBARK(f) (13.1*atan(.00074*(f))+2.24*atan((f)*(f)*1.85e-8)+1e-4*(f))
#define fromBARK(z) (102.*(z)-2.*pow(z,2.)+.4*pow(z,3)+pow(1.46,z)-1.)
#define toMEL(f) (log(1.+(f)*.001)*1442.695)
#define fromMEL(m) (1000.*exp((m)/1442.695)-1000.)
I was wondering if I could come
