# Sound Source Localization
Classical algorithms of sound source localization with beamforming, TDOA and high-resolution spectral estimation.

## Usage
```bash
matlab -nodesktop -nosplash –r matlabfile (name of .m)
```

## Algorithm Interpretation
* Beamforming: a spatial filtering method, is a signal processing technique used in sensor arrays for directional signal transmission or reception.
* MUSIC: Multiple Signal Classification
* ESPRIT: Estimation of Signal Parameters via Rotational Invariance Technique
* MVDR: Minimum Variance Distortionless Response
* GCC-PHAT: Generalized Cross Correlation - Phase Transform (TDOA estimation)
* SRP-PHAT: Steered Response Power - Phase Transform
