collect_single_register()

static void dpp::audio_mixer::collect_single_register ( int32_t *  data_in, int16_t *  data_out, float  current_gain, float  increment  )

inlinestatic

Collect a single register worth of data from data_in, apply gain and increment, and store the result in data_out. This version uses x64 instructions.

Parameters

data_in	Pointer to the input array of int32_t values.
data_out	Pointer to the output array of int16_t values.
current_gain	The gain to be applied to the elements.
increment	The increment value to be added to each element.

combine_samples()

static void dpp::audio_mixer::combine_samples ( int32_t *  up_sampled_vector, const int16_t *  decoded_data  )

inlinestatic

Combine a register worth of elements from decoded_data and store the result in up_sampled_vector. This version uses x64 instructions.

Parameters

up_sampled_vector	Pointer to the array of int32_t values.
decoded_data	Pointer to the array of int16_t values.
