I am using Nucleo f401-Re board with X-Nucleo-CCA02M1 board. I am experiencing with the sample Acoustic Sound Location code. I successfully uploaded and experienced with 4 microphone configuration. Now I am trying to work with 2 channel in 180 degree configuration. However, the angles are not accurate as much as 4 microphone configuration. Is there any suggestion about it? I changed the channel number in here : libSoundSourceLoc_Handler_Instance.channel_number = 2; and also here : libSoundSourceLoc_Handler_Instance.ptr_M1_channels = 2;
libSoundSourceLoc_Handler_Instance.ptr_M2_channels = 2;
libSoundSourceLoc_Handler_Instance.ptr_M3_channels = 2;
libSoundSourceLoc_Handler_Instance.ptr_M4_channels = 2;
If I choose 0 for M3 and M4 channels the system does not give any angles so I am working with these configuration but the angles are not accurate.
Looking forward to hearing something from you guys.
Thank you in advance,
