1-3 ウェーブレット変換を用いた単一音信号の音高推定法(第1部門 音声処理・セキュリティ)

抄録

We suggest a method for estimating the pitch of any single-tone signals, such as a voice and various instruments. Wavelet Transform can detect the reliable pitch in audio signals by the octave division. Experimental results show that our method is effective for estimating the pitch of real-world single-tone signals.
