gbr.wind= Apply a window to an incoming frame, grain or wave
Applies a chosen (and parametrized) window to the incomming fmat (column by column). The user can chose among various window types (see help patch).
arguments: <sym: function> [<any: parameters> ...] - window function and parameters ['hann']
attributes: none
messages: set <sym: function> [<any: parameters> ...] - set window function and parameters
inlets: 1 <fmat|fvec: vector> - input vector to be windowed
2 [<any: parameters> ...] - set window parameters
outlets: 1 <fmat|fvec: vector> - output incoming vector with applied window
gbr.yin Fundamentatal frequency estimation after de Cheveigné and Kawahara
Estimates fundamental frequency and outputs energy, periodicity factor, and auto correlation coefficients.
arguments: 1 <num: min freq> - lowest estimated frequency in Hz [50.]
2 - quality/periodicity threshold [0.68]
attributes: down <num: factor> - down sampling factor of incoming frames [1]
threshold <num: threshold> - quality/periodicity threshold
minfreq <num: min freq> - lowest estimated frequency in Hz
messages: down <num: factor> - down sampling factor of incoming frames [1]
threshold <num: threshold> - quality/periodicity threshold
minfreq <num: min freq> - lowest estimated frequency in Hz
inlets: 1 - signal frame (fmat or fvec
outlets: 1 <num: freq> - estimated frequency in Hz
2 <num: energy> - energy factor
3 <num: perodicity> - quality/periodicity factor
4 <num: ac1> - 2nd autocorrelation coefficient (ac1)
5 <fmat: acf> - vector of autocorrelation coefficients
