jamie@25: #X text 24 19 ________;
jamie@25: #X text 22 52 [xtract~] provides a wrapper for the feature extraction
jamie@25: library: LibXtract. Please refer to the documentation at libxtract.sourceforge.net
jamie@25: \, for a full explanation of the library and the functions it provides.
jamie@25: Only the operation of the PD external will be explained here along
jamie@25: with a few use case scenarios.;
jamie@25: #X text 20 148 [xtract~] must always be called with one argument \,
jamie@25: in the following form: [xtract~ <feature>] \, where <feature> is a
jamie@25: feature supported by the LibXtract library. A complete list of features
jamie@25: may be obtained by sending the external a |help( message:;
jamie@25: #X obj 27 262 xtract~;
jamie@25: #X msg 27 233 help;
jamie@25: #X text 26 298 Other than this help message \, the data sent to the
jamie@25: left inlet should always be a 'signal' (i.e. audio rate). This is the
jamie@25: data from a which a given feature will be extracted.;

jamie@25: #X text 39 641 Below are some possible use cases (click to open):;
jamie@25: #X text 26 352 The outlet may be a scalar (control rate) \, or a vector
jamie@25: (audio rate) \, depending on the nature of the feature that is being
jamie@25: extracted.;

jamie@62: #X text 27 405 Any additional arguments that need to be passed to the
jamie@62: feature extraction function must be provided as a list to the right
jamie@62: inlet \, e.g.;
jamie@25: #X connect 5 0 4 0;
jamie@62: #X connect 7 0 9 0;
jamie@62: #X connect 7 0 10 0;
jamie@62: #X connect 10 0 11 1;
jamie@62: #X connect 11 0 8 0;
jamie@62: #X connect 12 0 7 0;
