| Abstract(in English) | This paper proposes a new regularization term of non-negative matrix factorization(NMF) for estimating pitch and onset time of electric bass. Both of them are indispensable information for automatic music transcription. However, it is difficult to estimate them from the electric bass performance because of trade-off problem between time resolution and frequency resolution. Applying the NMF simply to the electric bass performance, the correct note and its semitone are sometime detected simultaneously. The proposed regularization term avoiding such miss detection based on the performance characteristic ofthe electric bass, that is, two notes are not generally played simultaneously. |
