Can you upload both the P and M files in the Algorithm file at the same time?

HauLiang commented 2 months ago

Okay, I have uploaded the .m files to the source_code folder. Please take a look and let me know if there's anything else you need.

Hello, I am very interested in your publicly available code. Do these localization algorithms have any requirements for sound source frequency? I converted the WAV recorded by the array to H5, ran the program, and the sound source was displayed in the center position. Is there any error？Can you add a contact information to inquire about some doubts？I am looking forward to your reply

Hello, thank you for your interest in our code. These algorithms are generally applicable to a wide range of frequency bands. However, when using your own data for beamforming, you may need to adjust some user-specific parameters in the code, such as:

fs (sampling frequency, important parameter)
z_source (z-axis distance)
scan_freq (the range of scanning frequency, important parameter)
scan_x and scan_y (the range of the scanning plane )

If you have any further questions, feel free to contact me. I look forward to your continued feedback!

In practical situations, the distance between the noise source and the microphone array is usually unknown. Under these conditions, how can we adjust the steerVector?
