sound-source-localization-algorithm_doa_estimation's Issues

srppaht其实是gccphat？

srp一般是多通道的gcc相加，这里只看见2通道的实现。希望能看到更新多通道的情况

ioa_stftCompute函数没有找到

老师您好，sound-source-localization-algorithm_DOA_estimation/ssl_tools/doa_mvdr.m 文件中第33行的ioa_stftCompute函数

我没有找到，请问我该如何解决？
可以使用spectrogram函数替换吗？

Are there references for several algorithms implemented in the code? For example, SRP-PHAT, nonlinear SRP-PHAT, MUSIC,

Are there references for several algorithms implemented in the code? For example, SRP-PHAT, nonlinear SRP-PHAT, MUSIC。
It helps me a lot to use the algorithm code that you completed. Can you give me the papers from which these algorithms came
在代码中实现的几个算法是否有参考?例如，SRP-PHAT，非线性SRP-PHAT, MUSIC。使用了您完成的算法代码这对我帮助很大，您能给出这些算法出自哪些论文吗

两个bug

有两个问题：
1.在music算法中 设定俯仰角范围为0 插值就会报错
2.SNR中 没有ioa_stftCompute函数

关于算法的适用性

老师您好，请问例子中的example.m, 对采集数据是否有要求？ 我使用的天线是任意面阵，四通道采集，数据带宽140MHz~300MHz，采样率1G。
