webrtc-beamforming's Introduction

webrtc-beamforming

整理出来的webrtc波束模块

步骤

mkdir build

cd build && cmake .. && make

注意:CMakeList中的目录路径可能需要自己替换,/build目录中已经有了编译好的可执行文件

使用说明

若输入的语音是几通道,那么麦克风的坐标就写几个

./webrtc-bf -i input.wav -mic_positions "x1 y1 z1 x2 y2 z2" -o output.wav

webrtc-beamforming's Issues

不工作

我用了10个mic的圆阵,发现出来变直线了

beamforming target

what is the angle of beam-forming target? Or, how can I configure my mic array to enhance people speak in the front of me?
Thank you in advance.

坐标原点是什么位置

你好,请问运行下面这行代码需要输入坐标
./webrtc-bf -i input.wav -mic_positions "x1 y1 z1 x2 y2 z2" -o output.wav
请问坐标的原点是什么呢?

output channel number

nice job!
In nonlinear_beamformer_test.cc
WavWriter out_file(FLAGS_o, in_file.sample_rate(), 1);
The output channel number needs to be the same as in_file.num_channels(). Otherwise the output signal would be interleaved.
correct me if I am wrong
