beamforming #201

Closed sagyHarpaz closed 3 years ago

sagyHarpaz commented 3 years ago

Hi all.

I have multichannel signal and I want to use beamforming on it. The signal recorded with single source with unknown position so I estimated the doa to get the directions but how can I perform delay and sum beamforming without knowing the position of the source?

thank.

If you just want to perform beamforming, it is not necessary to know the position of the source position but you should have the information of time delay. However, the doa estimation method proposed in pyroomacoustics search with azimuth rather than time delay.
