| gbr.addenv | Additive synthesis: generate partials with a given envelope | |||||||||||
| Adds partials with a spectral envolope (given as a vector or list) to an incoming spectrum using the FFT-1 technique. The output is typically connected to gbr.ifft (in real mode) or another gbr.addenv or gbr.addpartials module. | ||||||||||||
|
| gbr.addpartials | Additive synthesis: generate partials with given frequencies and amplitudes | |||||||||||
| Adds partials (given as a vector or list) to an incoming spectrum using the FFT-1 technique. The output is typically connected to gbr.ifft (in real mode) or another gbr.addpartials or gbr.addenv module. Frequencies and amplitudes can be given by separated vectors with separated inputs (input format 'vec') or as a single matrix to the first inlet. The input format (attribute @format) determines the interpretation of the columns of the incoming matrix: 'fa' requires 2 columns with frequencies and amplitudes, 'ifa' requires 3 columns with partial indices, frequencies and amplitudes. | ||||||||||||

|
| gbr.bands | FFT filter bands | |||||||||||
| Calculate filter bands from FFT spectrum. | ||||||||||||
|
| gbr.bq | Constant Q | |||||||||||
| Calculates a constant Q transform on an incoming spectrum [J.Brown, M.Puckette 1992]. Its input is typically connected to gbr.fft (in real mode). | ||||||||||||
|
| gbr.copy | Copy vector (fmat) out of a delay line or an fmat or fvec | |||||||||||

| Estimates frequencies (interpolated and scaled indices) and amplitudes of harmonics in an incoming vector. Harmonics are defined as peaks around the multiple of a given value (fundamental frequency) with a given tolerance. The estimation of harmonics in a spectrum works best when a logarthimic amplitude spectrum is provided as input. | ||||||||||||

| Calculates LPC coefficients from incoming sinal frame. | ||||||||||||
|
| gbr.mask | Partial masking using critical band width | |||||||||||
| Calculates and applies masking to incoming vector of partials.
