A Spatial Sampling Approach to Wave Field Synthesis: PBAP and Huygens Arrays

Autor: Smith III, Julius O.

A simple approach to microphone- and speaker-arrays is described in which the microphone array is regarded as a sampling grid for the acoustic field, and the corresponding speaker-array is treated as a "spatial digital to analog converter" that recon

Efficient Synthesis of Room Acoustics via Scattering Delay Networks

Autor: De Sena, Enzo, Hacihabiboglu, Huseyin, Cvetkovic, Zoran, Smith III, Julius O.

Publikováno v: IEEE/ACM Transactions on Audio, Speech, and Language Processing, Vol. 23, No. 9, September 2015

An acoustic reverberator consisting of a network of delay lines connected via scattering junctions is proposed. All parameters of the reverberator are derived from physical properties of the enclosure it simulates. It allows for simulation of unequal

Estimating a Signal from a Magnitude Spectrogram via Convex Optimization

Autor: Sun, Dennis L., Smith III, Julius O.

The problem of recovering a signal from the magnitude of its short-time Fourier transform (STFT) is a longstanding one in audio signal processing. Existing approaches rely on heuristics that often perform poorly because of the nonconvexity of the pro

On the Equivalence of the Digital Waveguide and Finite Difference Time Domain Schemes

Autor: Smith III, Julius O.

It is known that the digital waveguide (DW) method for solving the wave equation numerically on a grid can be manipulated into the form of the standard finite-difference time-domain (FDTD) method (also known as the ``leapfrog'' recursion). This paper
