示例1: ResamplePitch

/*
 * Resample voiced parts of pitch to match a given mean fundamential frequency.
 * The length of voiced segments is preserved to avoid loss of synchronization
 * between pitch and corresponding signal
 *
 * @param   idPitch     Source data instance containing original pitch
 * @param   idNewPitch  Target data instance containing new pitch
 * @param   nFFreq      Target fundamential frequency (mean over voiced parts)
