NAME Lutherie::FretCalc SYNOPSIS use Lutherie::FretCalc; my $fretcalc = Lutherie::FretCalc->new($scale_length); $fretcalc->in_units('in'); $fretcalc->out_units('in'); my $fret = $fretcalc->fret($fret_num); my @chart = fretcalc($num_frets); CONSTRUCTOR new ( SCALE_LENGTH ); This is the constructor for a new Lutherie::FretCalc object. SCALE_LENGTH is the numeric value for the scale length to be used for the calculation. The default value for scale length is 25. The unit can be set with the in_units() and out_units() methods. The default is 'in' (inches). METHODS scale ( [ SCALE_LENGTH ] ) If SCALE_LENGTH is passed, this method will set the scale length. The default value is 25. The scale length is returned. num_frets ( [ NUM_FRETS ] ) If NUM_FRETS is passed, this method will set the number of frets. The default value is 24. The number of frets is returned. fret_num ( [ FRET_NUM ] ) If FRET_NUM is passed, this method will set the fret number. The default value is 12. The fret number is returned. in_units ( [ IN_UNITS ] ) If IN_UNITS is passed, this method will set the in units. The default is 'in' (inches). The in unit is returned. 'in' - Inches, 'mm' - Millimeters out_units ( [ OUT_UNITS ] ) If OUT_UNITS is passed, this method will set the out units. The default is 'in' (inches). The out unit is returned. 'in' - Inches, 'mm' - Millimeters calc_method ( [ CALC_METHOD ] ) If CALC_METHOD is passed, this method will set the calc method. The default is 't' (tempered). The calc method is returned. 't': tempered - power of $i/$tet (default), 'ec': classic - 17.817, 'es': Sloane - 17.835, 'ep': Primative - 18 tet ( [ TET ] ) If TET is passed, this method will set the tones per ocatave. The default is 12. The number of tones per ocatave is returned. This value is only valid when using calc_method = 't'. half_fret ( [ FRET_NUM ] ) If FRET_NUM is passed, this method will calculate the half fret for this fret number. Valid values are 1, 6, 8 and 13. Only used with dulc_calc(). A comma separated list of half frets is returned. fret ( [ FRET_NUM ] ) Calculate the distance from the nut to the fret number. A scalar containing fret location for FRET_NUM is returned. fretcalc ( [ NUM_FRETS ] ) Calculate fret locations for given scale length, number of frets, calc type and tet. An ordered array containing fret locations from 1 to NUM_FRETS is returned. dulc_calc ( ) Calculate fret locations for mountain dulcimer. Number of frets is set at :w14. Half frets may be added by using half_fret() function. Valid half frets are 1+, 6+, 8+ and 13+. num_frets() will be ignored when using dulc_calc(). A hash containing fret locations from 1 to 14 is returned. Please let me know of any bugs you find or if you have any other routines you would like to contribute.
