TLDR
A bilinear transformation is applied to the linear prediction model on synthesis, using a recently described algorithm, which yields a computationally efficient way to generate a virtual string orchestra, with violin-, viola-, violoncello-, and bass-like timbres.
Abstract
A central problem in the production of music by computer is how to generate sounds with similar but different timbres; that is, how to synthesize a "family" of instruments that are perceived as distinguishable but similar in timbre. This paper describes a method for synthesizing a family of string-like instruments that proceeds as follows: First, a few actual violin notes are analyzed using linear prediction. Second, a bilinear transformation is applied to the linear prediction model on synthesis, using a recently described algorithm. This yields a computationally efficient way to generate a virtual string orchestra, with violin-, viola-, violoncello-, and bass-like timbres. A realization of a 4.7-minute piece composed by P. Lansky will be played.

Perceptual Synthesis Engine: An Audio-Driven Timbre Generator

Tristan Jehan
TL;DR: The thesis describes the modeling sequence including the analysis of natural sounds, the inference step that finds the mapping between control and output parameters, the timbre prediction step, and the sound synthesis.

NBody: Interactive Multidirectional Musical Instrument Body Radiation Simulators, and a Database of Measured Impulse Responses

Perry R. Cook, +1 more
TL;DR: Directional impulse responses were collected from stringed instruments, including guitar, mandolin, violin, and hardanger (Norwegian folk) fiddle, allowing sound to be projected in a performance space using the measured (or modified) transfer functions.

Toward the Perfect Audio Morph? Singing Voice Synthesis and Processing

TL;DR: A review of the popular methods and models used for the synthesis of the singing voice, discussing strengths and weaknesses of each technique, is given in this article, where a brief review is given of research on cross-modal visual/auditory perception of the human voice.

Structured encoding of the singing voice using prior knowledge of the musical score

TL;DR: This approach advances the singing voice closer towards a structured audio model in which musical parameters such as pitch, duration, and phonemes are represented orthogonally to the synthesis technique and can be modified prior to re-synthesis.

Roundoff noise in digital filters: Frequency transformations and invariants

TL;DR: The family of filters generated from a prototype filter H(z) is shown to possess certain common properties which are coordinate-free quantities which are invariant under frequency transformation, which is significant in the design of low-noise fixed-point digital filter structures.

Input Generators for Digital Sound Synthesis

TL;DR: In this paper, a fast method for generating a periodic discrete-time signal with harmonics of equal amplitude and a fundamental frequency which is not necessarily an integral fraction of the sampling frequency was described.
