Detailed Description

Library handler. It keeps track of the static parameters and it handles the internal state of the algorithm.

Field Documentation

uint32_t internal_memory_size

Keeps track of the amount of memory required for the current setup. It's filled by the libSpeexAEC_getMemorySize() function and must be used to allocate the right amount of RAM

uint32_t* pInternalMemory

Pointer to the memory allocated by the user

uint32_t preprocess_init

Specifies the option for the preprocessor uinitialization. This parameter can be a value of Acoustic_EC_preprocessor.

uint16_t ptr_output_channels

Specifies the number of channel in the Output Stream. Default Value is 1.

uint16_t ptr_primary_channels

Specifies the number of channel in the Primary Stream. Default Value is 1.

uint16_t ptr_reference_channels

Specifies the number of channel in the Reference Stream. Default Value is 1.

uint16_t tail_length

Specifies the length of the filter tail. Default Value is 512.
