示例1: file

{
bool fileLoaded = false;
if ( bodyfile != "" ) {
try {
FileWvIn file( bodyfile );
// Fill the StkFrames variable with the (possibly interpolated)
// file data.
excitation_.resize( (unsigned long) ( 0.5 + ( file.getSize() * Stk::sampleRate() / file.getFileRate() ) ) );
file.tick( excitation_ );
fileLoaded = true;
}
catch ( StkError &error ) {
oStream_ << "Guitar::setBodyFile: file error (" << error.getMessage() << ") ... using noise excitation.";
handleError( StkError::WARNING );
}
}
if ( !fileLoaded ) {
unsigned int M = 200; // arbitrary value
excitation_.resize( M );
Noise noise;
noise.tick( excitation_ );
// Smooth the start and end of the noise.
unsigned int N = (unsigned int) M * 0.2; // arbitrary value
for ( unsigned int n=0; n<N; n++ ) {
StkFloat weight = 0.5 * ( 1.0 - cos( n * PI / (N-1) ) );
excitation_[n] *= weight;

}
}
// Filter the excitation to simulate pick hardness
pickFilter_.tick( excitation_ );
// Compute file mean and remove (to avoid DC bias).
StkFloat mean = 0.0;
for ( unsigned int i=0; i<excitation_.frames(); i++ )
mean += excitation_[i];
mean /= excitation_.frames();
for ( unsigned int i=0; i<excitation_.frames(); i++ )
excitation_[i] -= mean;
// Reset all the file pointers.
