Abstract
Equipment (10) for reconstructing a recorded sound field includes a sensing arrangement (12) for measuring the sound field to obtain recorded data. A signal processing module (14) is in communication with the sensing arrangement (12) and processes the recorded data for the purposes of at least one of (a) estimating the sparsity of the recorded sound field and (b) obtaining plane-wave signals to enable the recorded sound field to be reconstructed.

1-89. (canceled)
A method of reconstructing a recorded sound field, the method including
- analysing recorded data in a sparse domain using one of a time domain technique and a frequency domain technique;
- and
- obtaining plane-wave signals and their associated source directions generated from the selected technique to enable the recorded sound field to be reconstructed.
