Detailed Description
Library handler. It keeps track of the static parameters and it handles the internal state of the algorithm.
Field Documentation
| uint32_t algorithm |
Specifies the algorithm to be used between XCORR and GCC-PHAT. This parameter can be a value of Acoustic_SL_algorithm_type. Default value is ACOUSTIC_BF_TYPE_CARDIOID_BASIC
| uint32_t channel_number |
Specifies the number of channels, can be 2 for 180� estimation, 4 for 360� estimation. Default value is
| uint32_t internal_memory_size |
Keeps track of the amount of memory required for the current setup. It's filled by the AcousticSL_getMemorySize() function and must be used to allocate the right amount of RAM
| uint16_t M12_distance |
Distance between Mic1 and Mic2 in decimals of a millimeter. Deafult value is 150.
| uint16_t M34_distance |
Distance between Mic3 and Mic4 in decimals of a millimeter. Deafult value is 150.
| uint32_t* pInternalMemory |
Pointer to the memory allocated by the user
| uint8_t ptr_M1_channels |
Number of channels in the stream of Microphone 1. Deafult value is 1.
| uint8_t ptr_M2_channels |
Number of channels in the stream of Microphone 2. Deafult value is 1.
| uint8_t ptr_M3_channels |
Number of channels in the stream of Microphone 3. Deafult value is 1.
| uint8_t ptr_M4_channels |
Number of channels in the stream of Microphone 4. Deafult value is 1.
| int16_t samples_to_process |
Specifies the number of samples to be processed at a time
| uint32_t sampling_frequency |
Specifies the sampling frequency - for future use
