Description

This is a MATLAB code repository for the manuscript below.

Taewoong Lee, Liming Shi, Jesper Kjær Nielsen, and Mads Græsbøll Christensen, ''Fast Generation of Sound Zones Using Variable Span Trade-Off Filters in the DFT-Domain,'' IEEE/ACM Transactions on Audio, Speech, and Language Processing, Nov. 2020, accepted for publication. IEEE Xplore

Note

Since the room impulse responses (RIRs) used in the manuscript is not able to be shared, simulated RIRs are used to reproduce the results described in the manuscript. Therefore, the results are similar but different from those in the manuscript.

The simulated RIRs were generated by using rir_generator, which can be downloaded from the following links: https://www.audiolabs-erlangen.de/fau/professor/habets/software/rir-generator

https://github.com/ehabets/RIR-Generator

Please run each section individually. Each section produces specific figures depicted in the paper. The same interpretation holds for the results from this repository, although different RIRs from those in the paper are found here.
