Abstract

This chapter takes a different approach to signal enhancement using spherical microphone arrays: a physically-motivated parametric representation of the sound field is introduced. It is shown that the sound field can be manipulated to achieve noise reduction or dereverberation by applying a time- and frequency-dependent gain to a reference signal. The gain is a simple function of the sound field parameters, which can be estimated using the methods presented in Chap. 5.

Notes

  1. 1.

    If the real SHT is applied instead of the complex SHT, the complex spherical harmonics \(Y_{lm}\) used throughout this chapter should be replaced with the real spherical harmonics \(R_{lm}\), as defined in Sect. 3.3.
