Synthesis of the Dan Trahn Based on a Parameter Extraction System

Analysis and synthesis processes for the dan tranh, a Vietnamese plucked string instrument, are described. In the analysis part, parameters are extracted from the decay region of recorded tones by using partial decay estimation and short-time Fourier transforms. The parameters of the string model are estimated, and the excitation signals for the model are extracted from recorded tones. The quality of synthesized tones is also studied based on different recorded data, numerous analyzed partials, and amplitude normalization. The results are compared with the Korean gayageum with silk strings and the acoustic guitar with steel strings. The quality of the synthesized sounds is verified by a multiple stimulus with hidden reference and anchor (MUSHRA) test. The average score was about 87, based on 100.
