Download Parametric Synthesis of Glissando Note Transitions - A user Study in a Real-Time Application
This paper investigates the applicability of different mathematical models for the parametric synthesis of fundamental frequency trajectories in glissando note transitions. Hyperbolic tangent, cubic splines and Bézier curves were implemented in a realtime synthesis system. Within a user study, test subjects were presented two-note sequences with glissando transitions, which had to be re-synthesized using the three different trajectory models, employing a pure sine wave synthesizer. Resulting modeling errors and user feedback on the models were evaluated, indicating a significant disadvantage of the hyperbolic tangent in the modeling accuracy. Its reduced complexity and low number of parameters were however not rated to increase the usability.
Download TU-Note Violin Sample Library – A Database of Violin Sounds with Segmentation Ground Truth
The presented sample library of violin sounds is designed as a tool for the research, development and testing of sound analysis/synthesis algorithms. The library features single sounds which cover the entire frequency range of the instrument in four dynamic levels, two-note sequences for the study of note transitions and vibrato, as well as solo pieces for performance analysis. All parts come with a hand-labeled segmentation ground truth which mark attack, release and transition/transient segments. Additional relevant information on the samples’ properties is provided for single sounds and two-note sequences. Recordings took place in an anechoic chamber with a professional violinist and a recording engineer, using two microphone positions. This document describes the content and the recording setup in detail, alongside basic statistical properties of the data.
