A FIR-based delay-and-sum beamformer with SIMD support.

Clone this project

git clone https://github.com/Irreq/neural-beamformer.git

Go to the directory

cd neural-beamformer

To use the delay functions, one must compile the code. If AVX instructions are available the user can use simd_delay instead of naive_delay which is oftentimes 100x faster than python3 numpy.convolve().

Compile using make

make

A shared object has now been created inside lib/ known as libdelay.so which can be used to delay signals.
