Correction dynamique et adaptative de la justesse en voix chantée
Résumé
This study presents the application of PitchWarping and Tuning (PWT) method to correct pitch from audio signalson real time. PWT use the dynamic pitch warping (DPW) method over fo of an incoming audio signal. Througha pitch velocity condition, the correction is released and adapted to the constantly changing pitch values, in thatway the curve of pitch is continuously adapted to the entry. At the end fo a soft curve on real time is generatedand the audio from incoming signal is forced to follow this curve. Several tests have been done using sinusoidalsignals and singing voice audio on real time, these results show a significant difference with the traditional pitchcorrection systems. Our proposal shows a soft variation of pitch that is released over a pitch’s velocity conditionwith an adaptive continuous modification
